+
+Ivan's description of the patch follows. Note that a few pieces like
+the GC_malloc(0) patch, were not applied since an alternate had been
+previously applied. A few differed stylistically from the rest of
+the code (mostly casts to void * instead of target type),
+or were classified as too minor to bother. Note that
+all of Ivan's static declarations which did not correct outright
+naming bugs (as a few did), where replaced by STATIC, which is
+ignored by default.
+
+- minor bug fixing (for FreeBSD, for THREAD_LOCAL_ALLOC and for
+GC_malloc(0));
+- addition of missing getter/setter functions for public variables
+(may be useful if compiled as Win32 DLL);
+- addition of missing GC_API for some exported functions;
+- addition of missing "static" declarator for internal functions
+and variables (where possible);
+- replacement of all remaining K&R-style definitions with ANSI
+C ones (__STDC__ macro is not used anymore);
+- addition of some Win32 macro definitions (that may be missing in
+the standard headers supplied with a compiler) for GWW_VDB mode;
+- elimination of most compiler warnings (except for
+"uninitialized data" warning);
+- several typos correction;
+- missing parenthesis addition in macros in some header files of
+"libatomic_ops" module.
+
+My highlights based on reading the patch:
+
+* allchblk.c: Remove GC_freehblk_ptr decl.

+GC_set_no_dls, GC_set_max_retries, GC_set_dont_precollect,
+GC_set_finalizer_notifier. Always define GC_win32_free_heap.

-
- Ivan's description of the patch follows. Note that a few pieces like
- the GC_malloc(0) patch, were not applied since an alternate had been
- previously applied. A few differed stylistically from the rest of
- the code (mostly casts to void * instead of target type),
- or were classified as too minor to bother. Note that
- all of Ivan's static declarations which did not correct outright
- naming bugs (as a few did), where replaced by STATIC, which is
- ignored by default.
-
- - minor bug fixing (for FreeBSD, for THREAD_LOCAL_ALLOC and for
- GC_malloc(0));
- - addition of missing getter/setter functions for public variables
- (may be useful if compiled as Win32 DLL);
- - addition of missing GC_API for some exported functions;
- - addition of missing "static" declarator for internal functions
- and variables (where possible);
- - replacement of all remaining K&R-style definitions with ANSI
- C ones (__STDC__ macro is not used anymore);
- - addition of some Win32 macro definitions (that may be missing in
- the standard headers supplied with a compiler) for GWW_VDB mode;
- - elimination of most compiler warnings (except for
- "uninitialized data" warning);
- - several typos correction;
- - missing parenthesis addition in macros in some header files of
- "libatomic_ops" module.
-
- My highlights based on reading the patch:
-
- * allchblk.c: Remove GC_freehblk_ptr decl.
- Make free_list_index_of() static.
- * include/gc.h: Use __int64 on win64, define GC_oom_func,
- GC_finalizer_notifier_proc, GC_finalizer_notifier_proc,
- add getter and setters: GC_get_gc_no, GC_get_parallel,
- GC_set_oom_fn, GC_set_finalize_on_demand,
- GC_set_java_finalization, GC_set_dont_expand,
- GC_set_no_dls, GC_set_max_retries, GC_set_dont_precollect,
- GC_set_finalizer_notifier. Always define GC_win32_free_heap.
- gc_config_macros.h: Define _REENTRANT after processing
- GC_THREADS.
- * include/gc_cpp.h: Improve GC_PLACEMENT_DELETE test,
- handling of operator new[] for old Windows compilers.
- * include/gc_inline.h (GC_MALLOC_FAST_GRANS): Add parentheses
- around arguments.
- * dbg_mlc.c, malloc.c, misc.c: Add many GC_API specs.
- * mark.c (GC_mark_and_push_stack): Fix source argument for
- blacklist printing.
- * misc.c: Fix log file naming based on environment variable
- for Windows. Make GC_set_warn_proc and GC_set_free_space_divisor
- just return current value with 0 argument. Add DONT_USE_USER32_DLL.
- Add various getters and setters as in gc.h.
- * os_dep.c: Remove no longer used GC_disable/enable_signals
- implementations. (GC_get_stack_base): Add pthread_attr_destroy
- call. No longer set GC_old_bus_handler in DARWIN workaround.
- * pthread_support.c: GC_register_my_thread must also
- call GC_init_thread_local.

+
+
+[7.0alpha7] 2006-09-19
+======================
+
+* More 6.7 changes.
+* Declare GC_dump() in gc.h.
+* Add --enable-large-config, which just defines the LARGE_CONFIG macro.
+* Make GlobalAlloc address alignment a bit more intuitive.
+* Use #elif in the definitions of GET_MEM.
+* Overhaul porting.html. Remove corresponding text from README.
+* Fix typo in DARWIN section of gcconfig.h.
+* Fix Darwin thread memory leak.
+* Update x86 AO_test_and_set implementation to use "=q".
+* Add $(EXEEXT) to many tests in tests/tests.am. (Corresponds to a
+6.7 fix, which no longer applied.)
+* Fix Darwin/PPC port.
+* Fix Cygwin/threads port.
+* Fix gcj malloc support.
+* For GNU-style make, don't build libatomic_ops unless threads are requested.
+This should allow single-threaded builds on platforms which do not
+currently support libatomic_ops.
+* Clean up and hopefully fix the CFLAGS calculation for GNU build.
+(Substantially improves things on HP/UX.)
+* Integrated Andrei Polushin's Visual C++ patches. These provide for
+stack traces, better C++ debug support, and better log file handling.
+Note that these change the location of the log file to a the path of the
+executable with a .log extension. To get the old behavior back, define
+OLD_WIN32_LOG_FILE. For the time being, I'm checking his project
+files and the like into a windows-untested subdirectory. They
+are almost certainly already out of date, but better than what we had
+before.
+* Fixed some win32 threads bugs, and added support for _beginthreadex.
+* Fix zero size thread local allocation so that explicit deallocation
+works correctly.
+* Removed serious bug in GC_malloc_uncollectable(large size).
+* Do not try to do thread-local gcj allocation in incremental mode. There
+are races in setting up the descriptor.
+* Add GC_INIT() to middle.c, fix some more GC_printfn calls.
+* Some assertions erroneously used I_HOLD_LOCK() negatively, even though
+it can now spuriously return TRUE.
+* Rename SUNOS5 macro and OS name to SOLARIS and SUNOS5DL to SOLARISDL.
+* On Linux and some Un*x variants, allocate memory by first trying sbrk,
+and then switching to mmap if that fails.
+* Fixed /proc/x/maps reading to deal with asynchronous deletions.
+* Fix REDIRECT_MALLOC with threads on Linux. It now usually seems to work
+with ugly hacks that include having calloc behave differently when it is
+called from ld.so or the pthreads library. A reasonable amount of
+infrastructure was added to support some of this.
+* Import various updated build scripts.
+* Add GC_register_has_static_roots_callback.
+* Fix serious bugs in GC_malloc_atomic_uncollectable().
+* Return GC_SUCCESS form GC_get_stack_base().
+* Fix several atomic_ops problems on IA64 with HP Compiler.
+* Update to atomic_ops-1.2.
+* Fix hb_n_marks description and reclaim.c assertion.
+* Various additional win32 threads fixes.
+* Enable GC_ASSERTIONS for Debug build with NT_THREADS_MAKEFILE.
+
+
+[7.0alpha5]
+===========
+
+* More 6.6, 6.7 changes.
+* Some Solaris fixes, including some more general changes in how
+the assembly pieces of mach_dep.c are handled.
+* Removed a lot of SOLARIS_THREADS-specific code that was only
+needed with the old implementation. This included many (mostly no-op)
+versions of GC_is_fresh.
+* Don't use atomic_ops in gc_locks.h unless we need threads.
+* Fixed USE_MARK_BITS, which is once again the default without PARALLEL_MARK.
+* Removed Solaris GC_INIT hack. It's a workaround for a long dead bug,
+and it seemed to be wrong anyway.
+* Changed win32_threads.c to require preprocessor-based interception
+of thread routines by default. A client call to GC_use_DllMain is
+now required to get the old behavior in which DllMain is used to implicitly
+register threads. This was done for uniformity with other platforms, and
+because the DllMain solution seemed to require very tricky code which,
+at least in the past, imposed hard bounds on the number of threads.
+* Many small changes to make thread support work again on Cygwin.
+* Moved definition of allocator lock etc. to pthread_support.c and
+win32_threads.c for those two cases.
+* Got rid of the FASTLOCK() machinery. It doesn't seem useful on modern
+platforms.
+* Cleaned up the uncollectable allocation routines, speeding up the
+slower paths. The code did enough unnecessary work off the critical path
+that the underlying logic was getting hard to extract.
+* No longer turn off THREAD_LOCAL_ALLOC with DBG_HDRS_ALL. Indications
+are it just works, and I think the reasons for it not working disappeared
+a while ago.
+* Fixed bugs in hb_n_marks calculation and assertion.
+* Don't use __builtin_expect for pre-3.0 gcc.
+* Define GWW_VDB only for recent Microsoft tool chains.
+* Add overview.html to doc directory.
+* Fix NT_STATIC_THREADS_MAKEFILE, various compiler warnings.
+* Made thread local allocation sort of work with Cygwin. The code should
+be there to deal with other Windows variants, But non-Cygwin Windows
+threads need more bug fixes.
+
+
+[7.0alpha4]
+===========
+
+* Various 6.5, 6.6 changes.
+* Removed GC_brief_async_signal_safe_sleep and used atomic_ops instead.
+* Integrated build patches from David Angelocola and Petter Urkedal.
+* Fix dynamic-linker-based pthread call redirection.
+* Renamed RS6000 to POWERPC/AIX.
+* Allow recovery from SIGSEGV in marker on Linux. This works around
+a race in thread stack marking if /proc is used to find roots. We do
+that by default with malloc redirection and threads. This involved
+moving some GC_find_limit and SETJMP related declarations to gc_priv.h.
+* Added doc/porting.html file.
+* Added ADD_HEAP_GUARD_PAGES for sbrk/*nix platforms to debug extreme
+memory overwrite errors.
+* Added trivial NO_INCREMENTAL flag to facilitate debugging.
+* Added GC_getattr_np-based GC_get_stack_base (untested).
+* Separated thread local allocation into a separate file and added the
+beginning of win32 support for that.
+
+
+[7.0alpha3]
+===========
+
+* Added support for dlopen-based interception of pthread functions.
+This is only half done. The gc.h redefinitions currently interfere.
+* Integrated major automake overhaul from Petter Urkedal.
+
+
+[7.0alpha2]
+===========
+
+* GC_bytes_allocd was incremented by a possibly uninitialized variable
+in GC_generic_malloc_inner. (Bug introduced in gc7.0alpha1.)
+* Win32 fixes.
+* Integrated Ben Hutchings' GetWriteWatch-based virtual dirty bit
+implementation for win32.
+* Removed pc_gc.tar and floppy targets in Makefile.direct. Removed
+pc_excludes file.
+* No longer include GC_bytes_wasted when evaluating allocation progress.
+Since we are now counting live memory, it no longer makes sense.
+* Applied Davide Angelocola's configure patch. There are now separate
+Makefile.am's in the cord and tests subdirectory, more tests, etc.
+* Renamed configure.in to configure.ac.
+* Merged a very small number of Nathanael Nerode's configure.ac
+cleanups from the gcc tree. Unfortunately, that file is a bit
+different from ours.
+* Changed EINTR handling in sem_wait slightly.
+* Restructure the root marking code. Remove all traces of
+USE_GENERIC_PUSH_REGS, and effectively make it the default.
+Make it easier to pass a context pointer to the mark routine, in
+case we ever want to do precise stack marking.
+* Replace GC_start_blocking() and GC_end_blocking() with GC_do_blocking().
+This remains undocumented, and only implemented for pthreads. But it
+removes an otherwise unavoidable race with stores of callee-save
+registers.
+* Fix GC_n_mark_bits for the default MARK_BIT_PER_GRANULE case. This
+resulted in bogus complaints in heap dumps.
+* Upgrade to libatomic_ops-1.0, and update build structure to match.
+* Remove SRC_M3 support. Clean up lock initialization code in misc.c.
+* Removed gc_local_alloc.h. If THREAD_LOCAL_ALLOC is defined, the
+thread local allocation routines are now called automatically.
+* Renamed gc_inl.h back to gc_inline.h. Changed the interface appreciably
+since locking has turned into a dominant issue, and in-line allocation
+only makes sense if it's no worse than thread-local allocation.
+Gc_inline.h is now also used to implement thread-local allocation.
+* Finished replacing stubborn allocation with manual write barrier.
+Untested.
+* Use thread-local allocation code by default.
+* Added GC_register_my_thread and friends for Posix and win32.
+* Patch for GWW_VDB from Ben Hutchings.
+* Removed explicit THREAD_LOCAL_ALLOC tests, since that now always
+redefines GC_malloc.
+* Removed now unused AIX memory allocation code.
+* Various minor fixes for bugs introduced in 7.0alpha1.
+
+
+[7.0alpha1]
+===========
+
+* Remove GC_PROTO, VOLATILE, GC_PTR, and GC_CONST. Assume ANSI C compiler
+and use ANSI constructs unconditionally.
+* Introduce #elif and #error in some of the appropriate places.
+* Remove GC_printf cruft. Use stdargs.
+* Remove separate Solaris threads support. Use the more generic Posix
+implementation.
+* Use atomic_ops for atomic operations and memory barriers.
+* Clean up MPROTECT_VDB implementation. Use SA_SIGINFO wherever
+possible.
+* Remove broken SIGNALS stuff.
+* Use size_t instead of word, where appropriate.
+* Add .S.o rule to Makefile.am.
+* Officially discontinue SunOS4, several old flavors of M68K (SunOS4,
+A/UX, HP), IBM PC/RTs and RISCOS/Irix4. (I doubt the old code worked.
+If anyone cares, these should be easy to resurrect.)
+* Add EXPECT() in some critical places.
+* Redefined hb_sz and hb_body to deal with bytes rather than words.
+This affected a great deal of code. I would like to consistently use
+byte offsets and sizes where there's not a convincing reason to do
+otherwise.
+* Redefined several other variables (GC_mem_found, GC_words_allocd)
+etc. to use units of bytes. Most of these were also renamed to
+reflect that fact.
+* Killed as many "register" declarations as possible.
+* Partially replaced stubborn allocation with manual write barrier.
+It's currently broken.
+* Restructured mark code, to allow mark bits to be kept either on
+a per allocation granule or per object basis. The emphasis is
+now on the -DUSE_MARK_BYTES option, since individual bits perform
+quite badly on hyper-threaded P4s, and are probably suboptimal on
+other architectures. -DUSE_MARK_BITS is currently broken, and may
+be resurrected only for the single-threaded case. This significantly
+reduced the cache footprint required by auxiliary GC data structures.
+It also reduces space overhead for small heaps. It probably slows
+things down slightly if interior pointers are very common.
+* As part of the above, we now maintain an approximate count of set
+mark bits in each heap block.
+* As part of the above, the semantics of hb_map changed drastically.
+For MARK_BIT_PER_OBJ, it doesn't exist. For MARK_BIT_PER_GRANULE,
+it is purely a way to replace a mod instruction with a table lookup.
+(Somewhat to my surprise, this still wins on modern hardware.)
+* Removed PRINTSTATS, GATHERSTATS, and SILENT macros. Everything is
+now controlled by GC_print_stats variable and GC_PRINT_STATS
+and new GC_PRINT_VERBOSE_STATS environment variables.
+* Add GC_log_printf and use it consistently for logging output.
+* Unconditionally count the objects we reclaim in the sweep phase.
+For thread local allocation, we need that anyway, and we expect
+that's increasingly the only case that matters. And it simplifies
+the code. In general expect minor performance hacks that benefit
+only the single-threaded case to disappear.
+* Remove GC_quiet from gc.h and elsewhere.
+* Changed the heap expansion heuristic, and the definition of
+GC_free_space_divisor, to refer to live data size, instead of total
+heap size. I believe this is much more robust. It wasn't previously
+possible, because we didn't have access to live data size.
+* Thread local allocation added the extra byte in twice: Once in
+thread_local_alloc, and once in malloc_many.
+* Removed GC_malloc_words_small and GC_gcj_fast_malloc. A new
+mechanism based on the thread local allocation data structures
+is expected to be added instead. This should allow inlined code
+that is both fast and doesn't rely on collector internals.
+* Changed both free lists and reclaim lists to be indexed by granules
+instead of words, norming halving their size.
+* MERGE_SIZE is now the only option, and the macro was removed.
+(Without it, we need a memory reference to GC_all_interior_pointers
+anyway. Thus it costs us nothing.)
+* Change GC_size_map to map to granules instead of words. Make sure
+that every possible size up to TINY_FREELISTS is present.
+* Split of macros need for fast inline allocation into gc_tiny_fl.h
+in anticipation of a new inline allocator that doesn't rely on GC
+internals.
+* Changed thread local allocation to use GRANULE_BYTES and TINY_FREELISTS
+in anticipation of a merge with the inline allocation code.
+* Removed ALIGN_DOUBLE. This is mostly handled by GRANULE_BYTES.
+* Make locking on most platforms conditional on GC_need_to_lock.
+
+
+[6.9]
+=====
+
+* Fix typo in PREFETCH implementation for X86_64.
+* Fix M68K LINUX port.
+* __GNUC__ was misspelled as __GNUC in new_gc_alloc.h.
+* Integrated Allan Hsu's patch for OS X VM deallocation problems.
+* Applied FreeBSD/X86_64 patch.
+
+
+[6.8]
+=====
+
+* Added some support for Dragonfly BSD.
+* Improvements to the HP/UX section of configure.in/configure.ac.
+* GC_unix_get_mem could neglect to release the malloc lock on Irix, under
+extremely unlikely circumstances.
+* Added support for kFreeBSD + glibc
+* Fix more MacOS threads memory leaks
+* Added initial Solaris/X86-64 support
+
+
+[6.7]
+=====
+
+* Add "int" to Solaris "end" and "etext" declaration in gc.h. Declared
+the symbols with underscores and as arrays, since that's what's actually
+used. Perhaps this could all just be removed.
+* Fixed ARM GC_test_and_set code.
+* Added casts for assignments to hb_last_reclaimed, which truncate the
+value. Added a cast to GC_adj_words_allocd. Use GetModuleHandleA
+when retrieving a handle to kernel32.dll under win32.
+* Added Tandem S-Series support.
+* Remove spurious gc:: qualifier for operator delete[] in gc_cpp.h.
+* Changed a test for LINUX in config_macros.h to one for __linux__.
+* Add prototypes for GC_finalizer_notifier and GC_thr_init.
+* Use ld instead of nonexistent ldz instruction in Darwin FindTopOfStack.
+* Add support for Darwin/X86.
+* Merge in some recent gcc fixes. Add ppc64 asm code.
+* Scan MEM_PRIVATE sections under Windows ME and predecessors.
+* Interior pointers with some largish offsets into large objects could
+be ignored, if GC_all_interior_pointers was set. (Oddly this worked
+correctly for stack references if it was not set. Otherwise it failed
+for both stack and heap references.)
+* Integrated Tatsuya Bizenn's NETBSD threads support, with some
+untested changes.
+* Added GC_strdup and friends to make leak detection work correctly
+for strdup clients. Fixed the existing strdup
+with malloc redirection to handle a null malloc return correctly.
+
+
+[6.6]
+=====
+
+* Fix CPU count detection for Irix and FreeBSD.
+* Integrate Dan Bonachea's patch for the IBM XLC compiler on Darwin.
+* Integrated Andreas Tobler's FreeBSD/PowerPC patch.
+* Don't access the GC thread structure from the restart handler. It's
+unsafe, since the handler may run too late.
+* Applied Christian Thalinger's patch to change comment syntax in
+alpha_mach_dep.S.
+* Added test for GC_no_dls in GC_dyld_image_add for DARWIN.
+* Use LINUX_STACKBOTTOM for Linux/SH and LINUX/ARM.
+* Rewrote GC_parse_map_entry. This assumed a fixed column layout of
+/proc/self/maps on Linux. This ceased to be true about 2 years ago.
+The old code is probably quite problematic with -DREDIRECT_MALLOC. It
+is also used by default for IA64, though I haven't seen actual failures
+there.
+* More consistently define HBLKSIZE to 4096 on 64 bit architectures with
+4K pages.
+* With win32 threads, GC_stop_world needs to acquire GC_write_cs.
+* Move up struct callinfo declaration to make gcc 4.0.2. happy.
+
+
+[6.5]
+=====
+
+* Integrated Paolo Molaro's patch to deal with EINTR in sem_wait.
+* Make GC_approx_sp() write to dummy location to ensure that stack
+is grown here, when sp looks reasonable, rather than later, when
+it might look like a bad memory reference. (Problem was never
+observed that I know of. But on rereading the code it seemed
+dubious.)
+* Separate out GC_with_callee_saves_pushed and sometimes call
+it from GC_suspend_handler in pthread_stop_world.c. Callee-save
+register values sometimes failed to get traced under HP/UX on
+PA-RISC. Linux/IA64 had the same problem, though non-stacked
+callee-save registers seem to be so rarely used there that nobody
+ever noticed.
+* Integrated an ancient Darwin powerpc_darwin_machine_dep.s patch
+from Andreas Tobler, which I had lost.
+* Fix compare_and_exchange implementation for gcc/IA64 to deal with
+pickier compiler versions.
+* Fixed Itanium 32-bit ABI support (HP/UX). In particular, the
+compare_and_exchange implementation didn't consider that possibility.
+* Undefine GC_pthread_detach in win32_threads.c.
+* Fixed inclusion of frame.h for NETBSD in os_dep.c.
+* Applied Dan Bonachea's patch to use mmap on AIX.
+* Several fixes to resurrect the Irix port on recent OS versions.
+* Change ALPHA to use LINUX_STACKBOTTOM.
+* Change SPARC64/LINUX to also use LINUX_STACKBOTTOM. Deal with potential
+bad values of __libc_stack_end on that platform.
+* Relax gctest to allow larger heap if ALIGN_DOUBLE isn't set.
+(Unnecessary in 7.0)
+* Force a define of __STDC__=0 for the IBM compiler on AIX, so that
+we get prototypes. (Unnecessary in 7.0)
+* GC_INIT definition for AIX and CYGWIN referred to DATASTART and DATAEND
+which are only defined in private include files.
+* Integrated some small gcconfig.h patches from Dan Bonachea. Also
+relaxed assertion about FreeBSD stack size in pthread_support.c.
+* Integrated Andrew Begel's darwin_stop_world.c patch for 64-bit
+support. This may need additional work.
+* Avoided potentially infinite recursion in GC_save_callers if
+the system backtrace calls malloc. The workaround currently requires
+__thread support if this code is used with threads.
+* Avoided another similar infinite recursion by conditionally
+invoking GC_save_callers in alloc.c.
+* Removed all traces of aix_irix_threads.c. AIX and Irix now use
+pthread_support.c and pthread_stop_world.c. The old code appeared
+to be unreliable for AIX, and was not regularly maintained.
+* On Irix, ignore segments with MA_FETCHOP or MA_NOTCACHED attributed;
+they're not always safe to read.
+* Fixed a previously vacuous assertion (diagnosed by the SGI compiler)
+in GC_remove_from_fl.
+* Fix stack_size assertion in GC_pthread_create.
+* Fix assertion in GC_steal_mark_stack.
+
+
+[6.4]
+=====
+
+* Merge gcconfig.h changes from gcc tree.
+* Unconditionally include gc_priv.h in solaris_pthreads.c, win32_threads.h,
+aix_irix_threads.c, and solaris_threads.c to get thread definitions.
+* Start marker threads in GC_thr_init, so that they get started even
+if no other threads are ever started. (Oddly enough, the parallel
+collector worked correctly, though not well, with no helper threads.)
+* Go ahead and split large blocks in GC_allochblk_nth if GC_dont_gc
+is set.
+* GC_PRINT_BACK_HEIGHT would deadlock with thread support.
+* Let in_progress_space in backgraph.s grow dynamically.
+* Fix README.solaris2. The GC_thr_init() hack doesn't work anymore.
+* Convert GC_finalizer_mem_freed to bytes in allchblk.c.
+* Add missing declaration for GC_generic_malloc_words_small_inner.
+Without it, s390x breaks.
+* Applied several MacOSX patches to support older tool chains.
+* Bug fix for NetBSD/amd64. Add NetBSD/sh3 support.
+* Fixed an uninitialized variable in cordprnt.c.
+* Eliminated some, but not all, gcc -Wall warnings.
+* Changed some old style casts to reinterpret_cast in new_gc_alloc.h.
+* GC_extend_size_map shouldn't adjust for GC_all_interior_pointers if
+GC_DONT_ADD_BYTE_AT_END is set.
+* Changed some (long) casts to (word) in preparation for win64.
+* Changed "int stack_size" declaration in pthread_support.c to use
+size_t. (Only mattered with GC_ASSERTIONS enabled.)
+* Added CRIS (etrax) support.
+* Removed GC_IGNORE_FB frame buffer recognition, and replaced
+it with a check that the mapping type is MEM_IMAGE.
+In theory, this should work much better, but it is a high
+risk change for win32.
+* GC_allochblk_nth incremented GC_words_wasted by bytes rather than
+words.
+* Consider GC_words_wasted in GC_adj_words_allocd only if it is within
+reason. (A hack to avoid some extremely unlikely scenarios in which
+we manage to allocate only "wasted" space. 7.0 has a better fix.)
+* Changed PowerPC GC_clear implementation to use lwsync instead of
+eieio, since the documentation recommends against eieio, and
+it seems to be incorrect if the preceding memory op is a load.
+* Fixed print_block_list to print the correct kind number for
+STUBBORN.
+* Have configure.in generate an error if it is asked to support
+pthreads, but doesn't know how to.
+* Added Kazuhiro Inaoka's patch for Renesas M32R support.
+* Have the GNU build mechanism link with -ldl. Rename THREADLIBS
+to THREADDLLIBS to reflect this.
+* Added Hannes Mehnert's patch for FreeBSD/SPARC support.
+* Merged some FreeBSD specific patches to threadlibs.c and dyn_load.c.
+* Define MPROTECT_VDB on MACOSX only if threads are being used, since the
+dirty page tracking mechanism uses threads. (This avoids an undefined
+reference to _GC_darwin_register_mach_handler_thread.)
+* By popular demand, use __libc symbols only if we are built with
+USE_LIBC_PRIVATES, which is off by default, and not otherwise documented.
+* Ignore GC_enable_incremental() requests when KEEP_BACK_PTRS is set.
+The GC itself will dirty lots of pages in this cases, probably making
+it counterproductive on all platforms. And the DARWIN port crashes.
+
+
+[6.3]
+=====
+
+* Compile test_cpp.cc with CXXCOMPILE instead of COMPILE.
+* Very large allocations could cause a collector hang. Correct
+calculation of GC_collect_at_heapsize.
+* GC_print_hblkfreelist printed some bogus results if USE_MUNMAP
+was defined.
+* Include gc_config_macros.h in threadlibs.c.
+* Correct MacOSX thread stop code.
+* SMALL_OBJ definition was off by one. This could cause crashes
+at startup.
+* Integrate Paolo Molara's patch to deal with a race in the Darwin
+thread stopping code.
+* Changed X86_64 implementation to use SA_SIGINFO in the MPROTECT_VDB
+implementation. The old approach appears to have been broken by
+recent kernels.
+* Added GC_ATTR_UNUSED to eliminate a warning in gc_allocator.h.
+* Fix GC_task_self declaration in os_dep.c.
+* Increase INITIAL_BUF_SZ in os_dep.c for Solaris /proc reads.
+
+
+[6.3alpha6]
+===========
+
+* Define USE_GENERIC_PUSH_REGS for NetBSD/M68K.
+* Fixed the X86_64 PREFETCH macros to correctly handle ia32e (which uses
+different prefetch instructions from AMD64).
+* GC_config_macros.h did not correctly define GC_WIN32_THREADS from
+GC_THREADS.
+* Added simple_example.html.
+* Merged Andrew Gray's patch to correctly restore signal handlers on
+FreeBSD.
+* Merged a patch from Andreas Jaeger to deal with prefetch-related warnings
+on x86-64. Added some other casts so that the PREFETCH macros
+always get a ptr_t argument. Removed some casts in the PREFETCH
+implementations.
+* Added a header guard for gc_allocator.h
+and changed GC_debug_free to clobber contents of deallocated object.
+* The signal masking code in pthread_stop_world.c contained some errors.
+In particular SIGSEGV was masked in the handler, in spite of the fact that
+it wrote to the heap. This could lead to an uncaught SIGSEGV, which
+apparently became much more likely in Linux 2.6. Also fixed some
+typos, and reduced code duplication in the same area.
+* Remove ltconfig, clean up configure messages for DGUX.
+* Integrated NetBSD/OpenBSD patches from Marc Recht and Matthias Drochner.
+
+
+[6.3alpha5]
+===========
+
+* Fix & vs && typo in GC_generic_malloc and
+GC_generic_malloc_ignore_off_page. (Propagated from the gcc tree.)
+* Removed SA_NODEFER hack from NetBSD and Solaris write-protect handler.
+(According to Christian Limpach, the NetBSD problem is fixed.
+Presumably so is the Solaris 2.3 problem.)
+* Removed placement delete from gc_cpp.h for the SGI compiler.
+* Changed semantics of the GC_IGNORE_FB environment variable.
+We still need help in identifying win32
+graphics memory mappings. The current "solution" is a hack.
+* Removed "MAKEOVERRIDES =" from Makefile.am and thus Makefile.in.
+It probably made more sense in the gcc context.
+* Explicitly ensure that NEED_FIND_LIMIT is defined for {Open,Net}BSD/ELF.
+* Replaced USE_HPUX_TLS macro by USE_COMPILER_TLS, since gcc often
+supports the same extension on various platforms.
+* Added some basic (completely untested) defines for win64, in support
+of future work.
+* Declared GC_jmp_buf in os_dep.s as JMP_BUF instead of jmp_buf, fixing
+a memory overwrite bug on Solaris and perhaps other platforms.
+* Added 0 != __libc_stack_end test to GC_linux_stack_base.
+Otherwise pre-linking could cause the collector to fail.
+* Changed default thread local storage implementation to USE_PTHREAD_SPECIFIC
+for HP/UX with gcc. The compiler-based implementation appears to work
+only with the vendor compiler.
+* Export GC_debug_header_size and GC_USR_PTR_FROM_BASE from gc_mark.h,
+making client mark code cleaner and less dependent on GC version.
+* Export several new procedures and GC_generic_malloc from gc_mark.h
+to support user-defined kinds. Use the new procedures to replace existing
+code in gcj_mlc.c and typd_mlc.c.
+* Added support for GC_BACKTRACES.
+* Fixed a remaining problem in CORD_str with signed characters.
+* Removed supposedly redundant, but very buggy, definitions of finalizer
+macros from javaxfc.h. Fortunately this file probably has no users.
+The correct declarations were already in gc.h.
+* Also need to set GC_in_thread_creation while waiting for GC during
+thread termination, since it is also possible to collect from an
+unregistered thread in that case.
+* Define NO_GETENV for Windows CE, since getenv doesn't appear to exist.
+Plus some other minor WinCE fixes.
+* Added GC_register_describe_type_fn.
+* Arrange for debugging finalizer registration to ignore non-heap
+registrations, since the regular version of the routine also behaves
+that way.
+* GC_gcj_malloc and friends need to check for finalizers waiting to be run.
+One of the more obscure allocation routines with missing a LOCK() call.
+* Fixed cvtres invocations in NT_MAKEFILE and NT_STATIC_THREADS_MAKEFILE
+to work with VS.NET.
+* Cleaned up GC_INIT calls in test. Updated gc.man to encourage GC_INIT
+use in portable code.
+* Taught the GC to use libunwind if --enable-full-debug is specified on
+IA64 and libunwind is present.
+* The USE_MUNMAP code could get confused about the age of a block and
+prematurely unmap it. GC_unmap_old had a bug related to wrapping of
+GC_gc_no. GC_freehblk and GC_merge_unmapped didn't maintain
+hb_last_reclaimed reasonably when blocks were merged. The code was
+fixed to reflect original intent, but that may not always be an
+improvement.
+
+
+[6.3alpha4]
+===========
+
+* USE_MMAP was broken by confusion in the code dealing with USE_MMAP_ANON.
+* Darwin support was broken in alpha3 as a result of my mis-integration of
+Andrew Begel's patches. Fixed with another patch from Andrew Begel.
+* A new sanity check in pthread_stop_world.c:GC_push_all_stacks() was
+overly aggressive. We may collect from an unregistered thread during
+thread creation. Fixed by explicitly checking for that case. (Added
+GC_in_thread_creation.)
+
+
+[6.3alpha3]
+===========
+
+* Removed -DSMALL_CONFIG from BCC_MAKEFILE.
+* Changed macros to test for an ARM processor (Patch from Richard Earnshaw.)
+* Mostly applied a DJGPP patch from Doug Kaufman. Especially Makefile.dj
+had suffered from serious bit rot.
+* Rewrote GC_apply_to_maps, eliminating an off-by-one subscript error,
+and a call to alloca (for lcc compatibility).
+* Changed USE_MUNMAP behavior on POSIX platforms to immediately remap
+the memory with PROT_NONE instead of unmapping it. The latter risks
+an intervening mmap grabbing the address space out from underneath us.
+Updated this code to reflect a cleaner patch from Ulrich Drepper.
+* Replaced _T with _Tp in new_gc_alloc.h to avoid a MACOS X conflict.
+(Patch from Andrew Begel.)
+* Dynamically choose whether or not lock should spin on win32.
+This may be a significant performance improvement for win32.
+* Fix Makefile.direct to actually include NT_STATIC_THREADS_MAKEFILE
+in the distribution.
+* Maybe_install_looping_handler() was accidentally exported, violating
+our name space convention.
+* Made os_dep.c use sigsetjmp and SA_NODEFER for NetBSD.
+* Integrated Andrew Begel's Darwin threads patch, adjusted according to
+some of Fergus Hendersons's comments. (Patch didn't apply cleanly,
+errors are possible.)
+* Added another test or two for the Intel 8.0 compiler to avoid
+confusing it with gcc. The single-threaded collector should now build
+with icc, at least on ia64.
+
+
+[6.3alpha2]
+===========
+
+* Re-enabled I_HOLD_LOCK assertion in aix_irix_threads.h.
+* Put back the WINABI qualifier for GC_CreateThread.
+* Sometimes explicitly define __private_extern__ before DARWIN dyld.h
+include.
+* Included signal.h from pthread_support.c. Removed GC_looping_handler,
+which was dead code.
+* GC_find_start was misdeclared by gc_pmark.h if PRINT_BLACK_LIST was
+defined.
+Changed GC_find_start to never just return 0. According to its
+comment it doesn't, and it's unclear that's correct.
+* GC_alloc_large had several largely compensating bugs in the
+computation of GC_words_wasted. (It was confused about bytes vs.
+words in two places.)
+* Integrated Slava Sysoltev's patch to support more recent versions of
+the Intel compiler on IA64/Linux.
+* Changed win32 spinlock initialization to conditionally set a spin count.
+(Emmanual Stumpf pointed out that enabling this makes a large performance
+difference on win32 multiprocessors.) Also cleaned up the win32 spinlock
+initialization code a bit.
+* Fixed thread support for HP/UX/IA64. The register backing store base for
+the main thread was sometimes not set correctly.
+* Added -DEMPTY_GETENV_RESULTS flag to work around Wine problem.
+* Declare GC_stack_alloc and GC_stack_free in solaris_threads.h to
+avoid 64-bit size mismatches.
+* Fixed GC_generic_push_regs to avoid a potential and very unfortunate
+tail call optimization. This could lead to prematurely reclaimed
+objects on configurations that used the generic routine and the new
+build infrastructure (which potentially optimizes mach_dep.c).
+This was a serious bug, but it's unclear whether it has resulted in
+any real failures.
+* Fixed CORD_str to deal with signed characters.
+* Merged a couple of NOSYS/ECOS tests into os_dep.c from gcj.
+* Partially merged a win32 patch from Ben Hutchings, and substantially
+revised other parts of win32_threads.c. It had several problems.
+Under MinGW with a statically linked library, the main thread was
+not registered. Cygwin detached threads leaked thread descriptors.
+There were several race conditions. For now, unfortunately the
+static threads limit remains, though we increased it, and made table
+traversal cost depend on the actual thread count.
+There is also still some code duplication with pthread_support.c.
+(Thread descriptors did become much smaller, since Ben Hutchings
+removed the thread context from them.)
+* Integrated a Solaris configure.in patch from Rainer Orth.
+* Added GC_IGNORE_FB and associated warning to very partially address
+the issue of the collector treating a mapped frame buffer as part
+of the root set.
+
+
+[6.3alpha1]
+===========
+
+* Integrated some NetBSD patches forwarded to me by Marc Recht. These
+were already in the NetBSD package.
+* GC_pthread_create waited for the semaphore even if pthread_create failed.
+Applied the analogous fix for aix_irix_threads.c.
+* Added Rainer Orth's Tru64 fixes.
+* The check for exceeding the thread table size in win32 threadDetach
+was incorrect.
+* Applied Andrew Begel's patch to correct some reentrancy issues
+with dynamic loading on Darwin.
+* GC_CreateThread() was neglecting to duplicate the thread handle in
+the table.
+* Pass +ESdbgasm only on PA-RISC machines with vendor compiler.
+* Applied more AIX threads patches from Scott Ananian.
+
+
+[6.2]
+=====
+
+* Integrated a second round of Irix/AIX patches from Dan Bonachea.
+Renamed mips_sgi_mach_dep.S back to mips_sgi_mach_dep.s, since it requires
+the Irix assembler to do the C preprocessing; gcc -E doesn't work.
+* Fixed Makefile.direct for DARWIN.
+* There was a race between GC_pthread_detach and thread exit that could
+result in a thread structure being deallocated by GC_pthread_detach
+even though it was still needed by the thread exit code.
+* Fixed version parsing for non-alpha versions in acinclude.m4 and
+version checking in version.h.
+
+
+[6.2alpha6]
+===========
+
+* There was an extra underscore in the name of GC_save_registers_in_stack
+for NetBSD/SPARC.
+* Integrated Brian Alliet's patch for Darwin. This restructured the
+linuxthreads/pthreads support to separate generic pthreads support
+from more the system-dependent thread-stopping code. I believe this
+should make it easier to eliminate the code duplication between
+pthreads platforms in the future. The patch included some other
+code cleanups.
+* Integrated Dan Bonachea's patch to support AIX threads. This required
+substantial manual integration, mostly due to conflicts with other
+recent threads changes. It may take another iteration to
+get it to work.
+* Removed HPUX/PA-RISC support from aix_irix_threads.c. It wasn't used
+anyway and it cluttered up the code. And anything we can do to migrate
+towards generic pthreads support is a good thing.
+* Added a more explicit test for tracing of function arguments to test.c.
+* Added Akira Tagoh's PowerPC64 patch.
+* Fixed some bit rot in the Cygwin port.
+gc.h now includes just windows.h, not winbase.h.
+* Declared GC_save_regs_in_stack() in gc_priv.h. Remove other declarations.
+* Changed --enable-cplusplus to use automake consistently. The old way
+confused libtool. "Make install" didn't work correctly for the old version.
+Previously --enable-cplusplus was broken on cygwin.
+* Changed the C version of GC_push_regs to fail at compile time if it is
+generated with an empty body. This seems to have been the cause of one
+or two subtle failures on unusual platforms. Those failures should
+now occur at build time and be easily fixable.
+
+
+[6.2alpha5]
+===========
+
+* GC_invoke_finalizers could, under rare conditions, set
+GC_finalizer_mem_freed to an essentially random value. This could
+possibly cause unbounded heap growth for long-running applications
+under some conditions. (The bug was introduced in 6.1alpha5, and
+is not in gcc3.3.)
+* Attempted to sanitize the various DLL macros. GC_USE_DLL disappeared.
+GC_DLL is used instead. All internal tests are now on GC_DLL.
+README.macros is now more precise about the intended meaning.
+* Include DllMain in the multithreaded win32 version only if the
+collector is actually built as a dll.
+* Hide the cygwin threadAttach/Detach functions. They were violating our
+namespace rules.
+* Fixed an assertion in GC_check_heap_proc. Added GC_STATIC_ASSERT.
+* Removed some obsolete definitions for Linux/PowerPC in gcconfig.h.
+* CORD_cat was not rebalancing unbalanced trees in some cases, violating
+a CORD invariant. Also tweaked the re-balancing rule for
+CORD_cat_char_star.
+* Added hand-coded structured exception handling support to mark.c.
+This should enable support of dynamic libraries under win32 with
+gcc-compiled code.
+Turned on dynamic library scanning for win32/gcc.
+* Removed some remnants of read wrapping.
+GC_USE_LD_WRAP ws probably broken in recent versions.
+* The build could fail on some platforms since gcconfig.h could include
+declarations mentioning ptr_t, which was not defined, e.g. when if_mach
+was built. Also
+cleaned up tests for GC_PRIVATE_H in gcconfig.h a bit.
+* The GC_LOOP_ON_ABORT environment variable interfered with incremental
+collection, since the write fault handler was erroneously overridden.
+Handlers are now set up in the correct order.
+* It used to be possible to call GC_mark_thread_local_free_lists() while
+the world was not stopped during an incremental GC. This was not safe.
+Fortunately, it was also unnecessary. Added GC_world_stopped flag
+to avoid it. (This caused occasional crashes in GC_set_fl_marks
+with thread local allocation and incremental GC. This probably happened
+primarily on old, slow multiprocessors.)
+* Allowed overriding of MAX_THREADS in win32_threads.c from the build
+command line.
+* Taught the IA64/linux code to determine the register backing store base from
+/proc/self/maps after checking the __libc symbol, but before guessing.
+(__libc symbols are on the endangered list, and the guess is likely to not
+always be right for 2.6 kernels.) Restructured the code to read and parse
+/proc/self/maps so it only exists in one place (all platforms).
+* The -DUSE_PROC_FOR_LIBRARIES code was broken on Linux. It claimed that it
+also registered the main data segment, but didn't actually do so. (I don't
+think anyone actually uses this configuration, but ...)
+* Made another attempt to get --enablecplusplus to do the right thing.
+Since there are unavoidable problems with C programs linking against a
+dynamic library that includes C++ code, I separated out the c++ code into
+libgccpp.
+
+
+[6.2alpha4]
+===========
+
+* Use LINUX_STACKBOTTOM for >= glibc2.2 on Linux/MIPS. (See Debian bug
+# 177204)
+* Integrated Jeff Sturm and Jesse Rosenstock's MACOSX threads patches.
+* Integrated Grzegorz Jakacki's substantial GNU build patch. "Make dist"
+should now work for the GNU build process. Documentation files
+are installed under share/gc.
+* Tweaked gc_cpp.h to again support the Borland compiler.
+* Updated BCC_MAKEFILE.
+* Added GC_ASSERT check for minimum thread stack size.
+* Added --enable-gc-assertions.
+* Added some web documentation to the distribution. Updated it in the
+process.
+* Separate gc_conf_macros.h from gc.h.
+* Added generic GC_THREADS client-defined macro to set the appropriate
+GC_XXX_THREADS internal macro. (gc_config_macros.h.)
+* Add debugging versions of _ignore_off_page allocation primitves.
+* Moved declarations of GC_make_closure and GC_debug_invoke_finalizer
+from gc.h to gc_priv.h.
+* Reset GC_fail_count even if only a small allocation succeeds.
+* Integrated Brian Alliet's patch for dynamic library support on Darwin.
+* gc_cpp.h's gc_cleanup destructor called GC_REGISTER_FINALIZER_IGNORE_SELF
+when it should have called the lower case version, since it was
+explicitly computing a base pointer.
+
+
+[6.2alpha3]
+===========
+
+* Don't include execinfo.h in os_dep.c when it's not needed, and may not
+exist.
+
+
+[6.2alpha2]
+===========
+
+* Fixed the completely broken FreeBSD code in 6.2alpha1.
+* Changed IRIX reference in dbg_mlc.c to IRIX5.
+* Attempted to work around the problems with .S filenames and the SGI
+compiler. (Untested.)
+* Worked around an HP/UX make issue with the GNU-style build process.
+* Fixed the --enable-cplusplus build machinery to allow builds without
+a C++ compiler. (That was always the intent ...)
+* Changed the debugging allocation macros to explicitly pass the return
+address for Linux and XXXBSD on hardware for which we can't get stack
+traces. Use __builtin_return_address(0) to generate it when possible.
+Some of the configuration work was cleaned up (good) and moved to gc.h
+(bad, but necessary). This should make leak detection more useful
+on a number of platforms.
+* Fixed compilation problems in dbg_mlc.c with GC_ADD_CALLER.
+* Bumped revision number for dynamic library.
+
+
+[6.2alpha1]
+===========
+
+* Guard the test for GC_DUMP_REGULARLY in misc.c with
+"#ifndef NO_DEBUGGING". Otherwise it fails to build with NO_DEBUGGING
+defined.
+* Message about retrying suspend signals was incorrectly generated even when
+flag was not set.
+* Cleaned up MACOSX/NEXT root registration code. There was apparently a
+separate ifdef case in GC_register_data_segments() for no reason.
+* Removed MPROTECT_VDB for MACOSX port, based on one negative report.
+* Arrange for gc.h and friends to be correctly installed with GNU-style
+"make install".
+* Enable the GNU-style build facility include C++ support in the library
+with --enable-cplusplus.
+* Mark from GC_thread_key in linux_threads.c, in case that's allocated
+from the garbage collected heap, as it is with our own thread-specific
+storage implementation.
+* Mark all free list header blocks if they are heap allocated. This avoids
+some unnecessary tracing. And it remains correct if we clear the
+root set.
+* Improved S390/Linux support. Add S390/Linux 64-bit support.
+* Corrected the spelling of GC_{M,C}ALLOC_EXPLICTLY_TYPED to
+GC_{M,C}ALLOC_EXPLICITLY_TYPED in gc_typed.h. This is technically
+an interface change. Based on the fact that nobody reported this,
+I suspect/hope there were no clients.
+* Cleaned up gc_typed.h so that (1) it adds an extern "C" declaration
+when appropriate, (2) doesn't generate references to undefined internal
+macros, and (3) allows easier manual construction of descriptors.
+* Close the file descriptor used by GC_print_address_map().
+* Set the "close-on-exec" bit for various file descriptors maintained
+for the collector's internal use.
+* Added a hack to find memory segments owned by the system allocator
+under win32. Based on my tests, this tends to eventually find all
+segments, though it may take a while. There appear to be cleaner,
+but slower solutions under NT/XP. But they rely on an API that's
+unsupported under 9X.
+* Changed Linux PowerPC stack finding to LINUX_STACKBOTTOM.
+* Added GC_set_free_space_divisor to avoid some Windows dll issues.
+* Added FIXUP_POINTER, POINTER_SHIFT, POINTER_MASK to allow preprocessing
+of candidate pointers for tagging, etc.
+* Always lock around GC_notify_full_gc(). Simplified code for
+invoking GC_notify_full_gc().
+* Changed the way DATASTART is defined on FreeBSD to be robust against
+an unmapped page after etext.
+* Made GC_enable() and GC_disable() official. Deprecated direct update
+of GC_dont_gc. Changed GC_gcollect to be a noop when garbage collection
+is disabled.
+* Call GC_register_dynamic_libraries before stopping the world on Linux,
+in order to avoid a potential deadlock due to the dl_iterate_phdr lock.
+* Introduced a more general mechanism for platform-dependent code to
+decide whether the main data segment should be handled separately
+from dynamic libraries, or registered by GC_register_dynamic_libraries.
+The latter is more reliable and easier on Linux with dl_iterate_phdr.
+
+
+[6.1]
+=====
+
+* Added GC_MAXIMUM_HEAP_SIZE environment variable.
+* Fix configure.in for MIPS/LINUX.
+* Double page hash table size for -DLARGE_CONFIG.
+* Integrated Bo Thorsen's X86-64 support.
+* STACKBOTTOM definition for LINUX/MIPS was partially changed back.
+* Replaced all occurrences of LINUX_DATA_START in gcconfig.h with
+SEARCH_FOR_DATA_START. It doesn't hurt to falll back to a search.
+And __data_start doesn't seem to get defined correctly of the GC
+library is loaded with LD_PRELOAD, e.g. for leak detection.
+* If the GC_find_leak environment variable is set, do a
+atexit(GC_gcollect) to give us at least one chance to detect leaks.
+This may report some very benign leaks, but ...
+* Addeded REDIRECT_FREE. It's necessary if we want leak detection with
+LD_PRELOAD.
+* Defer printing of leaked objects, as for smashed objects.
+* Fixed process and descriptor leak in GC_print_callers. Try for
+line number even if we got function name.)
+* Ported parallel GC support and thread local allocation to Alpha.
+Not yet well-tested.
+* Added GC_DUMP_REGULARLY and added finalization statistics to GC_dump().
+* Fixed Makefile.am to mention alpha_mach_dep.S instead of the defunct
+alpha_mach_dep.s.
+* Incorporated a change to new_gc_alloc.h,
+which should make it work with gcc3.1.
+* Use alpha_mach_dep.S only on Linux. (It's not clear that this is
+optimal, but it otherwise didn't build on Tru64.)
+* Added ifdef to guard free() in os_dep.c. Otherwise we get a
+compilation error on Irix.
+* Added an experimental version of GC_memalign to mallocx.c. This can't
+always work, since we don't handle alignment requests in the hblk-level
+allocator, and we can't handle arbitrary pointer displacements unless
+GC_all_interior_pointers is enabled. But it should work for alignment
+requests up to HBLKSIZE. This is not yet documented in the standard
+places.
+* Finally debugged the OSF1/Tru64 thread support. This needs more testing,
+since I needed to add a somewhat unconvincing workaround for signal
+delivery issues that I don't yet completely understand. But it does
+pass my tests, even in parallel GC mode. Incremental GC support is
+disabled if thread support is enabled, due to the signal issues.
+* Eliminated name-space-incorrect definition of _cdecl from gc_cpp.h.
+* Added GC_debug_malloc_replacement and GC_debug_realloc_replacement
+declarations to gc.h. On IA64, this is required for REDIRECT_MALLOC
+to work correctly with these.
+* Fixed Linux USE_PROC_FOR_LIBRARIES to work with a 64-bit /proc format.
+
+
+[6.1alpha5]
+===========
+
+* Added GC_finalizer_mem_freed, and changed some of the code that
+decided on heap expansion to look at it. Memory explicitly
+deallocated by finalizers essentially needs to be counted as reclaimed
+by the GC. Otherwise there are cases in which the heap can grow
+infinitely.
+* Integrated Adam Megacz patches to not scan dynamic libraries if
+we are compiling with gcc on win32. Otherwise we need structured
+exception handling to deal with asynchronously unmapped root
+segments, and gcc doesn't directly support that.
+* Integrated Anthony Green's patch to support Wine.
+* GC_OPERATOR_NEW_ARRAY was misspelled OPERATOR_NEW_ARRAY in several
+places, including gc_cpp.cc.
+* Integrated Loren James Rittle's Alpha FreeBSD patches. These also
+changed the declarations of symbols like _end on many platforms to
+that they wouldn't mistakenly be declared as short data symbols.
+* Integrated changes from the Debian distribution.
+Fix C++ comments in POWERPC port. Add ARM32
+incremental GC support. Get rid of USE_GENERIC_PUSH_REGS for alpha/Linux,
+this time for real. Use va_copy to get rid of cord printf problems
+(finally).
+* Close file descriptor used to count cpus.
+* Don't just drop gcj free lists in GC_start_reclaim, since that can
+eventually cause the marker to see a bogus mark descriptor in the
+dropped objects. The usual symptom was a very intermittent segmentation
+fault in the marker. This mattered only if one of the GC_gcj_malloc
+variants was used.
+* Fixed Linux and Solaris/64 SPARC configuration.
+* Fixed a typo in strdup definition.
+* Changed Makefile.direct to invoke $(CC) to assemble alpha_mach_dep.S.
+This is needed on Linux. I'm not sure whether it's better or worse
+on Tru64.
+* Changed gc_cpp.h once more to declare operator new and friends only in
+a Microsoft environment. This may need further fine tuning.
+* Don't ever override strdup if it's already macro defined.
+* Changed gc_cpp.h yet again to also overload placement new. Due to the
+C++ overloading rules, the other overloaded new operations otherwise hide
+placement new, which causes many STL uses to break.
+* Integrated cygwin pthreads support from Dan Bonachea.
+* Turn on DYNAMIC_LOADING for NetBSD.
+* Changed printing code to print more complete GC times.
+* Applied Mark Mitchell's Irix patch to correct some bitrot.
+* Clarified which object-printing routines in dbg_mlc.c should hold
+the allocation lock. Restructured the code to allow reasonable object
+printing with -DREDIRECT_MALLOC.
+* Fix the Linux mmap code to always start with 0x1000 as the initial hint.
+Minor patches for 64-bit AIX, particularly to STACKBOTTOM.
+* Renamed "SUSPENDED" flag for Solaris threads support to avoid a conflict
+with a system header.
+* Cause win32_threads.c to handle an out of range stack pointer correctly,
+though currently with a warning.
+
+
+[6.1alpha4]
+===========
+
+* Fixed typo in sparc_mach_dep.S, preventing the 64-bit version from
+building. Increased 64-bit heap size limit in test.c slightly, since
+a functional SPARC collector seems to slightly exceed the old limits.
+* Use NPRGREG in solaris_threads.c, thus printing all registers if things
+go wrong.
+* Added GC_MARKERS environment variable to allow use of a single marker
+thread on an MP without confusing the lock implementation.
+* Collect much less aggressively in incremental mode with GC_TIME_UNLIMITED.
+This is really a purely generational mode, and we can afford to
+postpone the collection until the heap is (nearly) full.
+* Remove read() wrapper for MPROTECT_VDB. It was causing more harm than
+good. It is often no longer needed if system calls avoid writing to
+pointerfull heap objects.
+* Fix MACOSX test in gcconfig.h.
+* Change GC_test_and_set so that it consistently has one argument.
+Add spaces to ::: in powerpc assembly code in gc_locks.h.
+* Fixed a formatting error in dbg_mlc.c. Added prototype to GC_abort()
+declaration.
+* Removed "source" argument to GC_find_start(). Eliminate GC_FIND_START().
+* Added win32 recognition code in configure.in. Changed some of the
+dllimport/export defines in gc.h.
+* GC_malloc_many didn't set hb_last_reclaimed when it called
+GC_reclaim_generic. (I'm not sure this matters much, but ...)
+* Allocating uncollectable objects with debug information sometimes
+allocated objects that were one byte too small, since uncollectable
+objects don't have the extra byte added at the end.
+* Added a bit more assertion checking to make sure that gcj objects
+on free lists never have a nonzero second word.
+* Replaced BCC_MAKEFILE with an up-to-date one.
+* Upgraded libtool, cinfigure.in and some related files to hopefully
+support NetBSD/SPARC. Unfortunately,
+libtool 1.4.2 seemed to be buggy due to missing quotes in several
+"test" invocations. Fixed those in the ltmain.sh script.
+* Some win32-specific patches, including the introduction of
+GC_CreateThread.
+* Merged in gcj changes from Anthony Green to support embedded systems.
+* Tried to consistently rename preprocessed assembly files with a capital
+.S extension.
+* Use alpha_mach_dep.S on ALPHA again. It doesn't really matter, but this
+makes our distribution consistent with the gcc one, avoiding future merge
+problems.
+* Move GET_MEM definition into gcconfig.h. Include gcconfig.h slightly
+later in gc_priv.h to avoid forward references to ptr_t.
+* Add some testing of local allocation to test.c.
+* Change definition of INVALID_QTID in specific.h. The -1 value was used
+inconsistently, and too likely to collide with a valid stack address.
+Some general clean-up of specific.[ch]. Added assertions.
+* On Pthread systems it was not safe to call GC_malloc() between fork()
+and exec(). According to the applicable standards, it doesn't appear
+to be safe to call malloc() or many other libc functions either, thus
+it's not clear this is fixable. Added experimental support for
+-DHANDLE_FORK in linux_threads.c which tries to support it. It may
+succeed if libc does the right thing. I'm not sure whether it does.
+* Documented thread local allocation primitives to require an
+explicit GC_init call. GC_init_parallel is no longer declared to
+be a constructor function, since that isn't portable and often
+seems to lead to initialization order problems.
+* Changed gc_cpp.cc and gc_cpp.h in one more attempt to make them
+compatible with Visual C++ 6.
+* Some more patches for Linux on HP PA-RISC.
+* Added include/gc_allocator.h. It implements (hopefully) standard
+conforming (as opposed to SGI-style) allocators that allocate
+collectable (gc_allocator) or GC-traceable, but not collectable
+(traceable_allocator) objects. This borrows heavily from libstc++,
+which borrows heavily from the SGI implementation, this part of
+which was written by Matt Austern. Changed test_cpp.cc to very
+minimally test this.
+* On Linux/X86, retry mmap with a different start argument. That should
+allow the collector to use more (closer to 3GB) of the address space.
+* Force 64 bit alignment with GCJ support.
+* Refined the choice of sa_handler vs. sa_sigaction in GC_dirty_init
+to accommodate some glibc5 systems.
+* Compensated for the fact that current versions of glibc set
+__libc_stack_end incorrectly on Linux/IA64 while initialization code
+is running. This could cause the collector to miss 16 bytes of
+the memory stack if GC_malloc or friends where called before main().
+* Mostly integrated Takis Psarogiannakopoulos' port to DG/UX Inix 86.
+This will probably take another iteration to work, since his
+patch conflicted with the libtool upgrade.
+* Added README.arm.cross containing some information about cross-
+compiling to an ARM processor from Margaret Fleck.
+
+
+[6.1alpha3]
+===========
+
+* Minor cleanup on the gcconfig.h section for SPARC.
+* Minor fix to support Intel compiler for I386/Linux.
+* Added SPARC V9 (64-bit) support.
+* Restructured the way in which we determine whether or not to keep
+call stacks for debug allocation. By default SAVE_CALL_COUNT is
+now zero on all platforms. Added SAVE_CALL_NARGS parameters.
+If possible, use execinfo.h to capture call stack. (This should
+add support for a number of new platforms, though often at
+considerable runtime expense.)
+* Try to print symbolic information for call stacks. On Linux, we
+do this with a combination of execinfo.h and running addr2line in
+a separate process. This is both much more expensive and much more
+useful. Amazingly, it seems to be fast enough for most purposes.
+* Redefined strdup if -DREDIRECT_MALLOC is given.
+* Changed incremental collector and MPROTECT_VDB implementation so that,
+under favorable conditions, pointer-free objects are not protected.
+Added GC_incremental_protection_needs() to determine ahead of time whether
+pointer-free objects may be protected. Replaced GC_write_hint() with
+GC_remove_protection().
+* Added test for GC_ENABLE_INCREMENTAL environment variable.
+* Made GC_time_limit runtime configurable. Added GC_PAUSE_TIME_TARGET
+environment variable.
+* Eliminated GC_page_sz, a duplicate of GC_page_size.
+* Caused the Solaris and Irix thread creation primitives to call
+GC_init_inner().
+
+
+[6.1alpha2]
+===========
+
+* No longer wrap read by default in multi-threaded applications. It was
+pointed out on the libgcj list that this holds the allocation lock for
+way too long if the read blocks. For now, reads into the heap are
+broken with incremental collection. It's possible to turn this back on
+if you make sure that read calls don't block (e.g. by calling select
+first).
+* Fix ifdef in Solaris_threads.h to refer to GC_SOLARIS_THREADS.
+* Added check for environment variable GC_IGNORE_GCJ_INFO.
+* Added printing of stop-the-world GC times if GC_PRINT_STATS environment
+variable is set.
+* The calloc definition in leak_detector.h was missing parentheses, and
+realloc was missing a second argument to GC_REALLOC.
+* Added GC_PRINT_BACK_HEIGHT environment variable and associated
+code, mostly in the new file backgraph.c. See doc/README.environment.
+* Added -DUSE_GLOBAL_ALLOC to work around a Windows NT issue.
+* Integrated port to NEC EWS4800 (MIPS-based workstation, with somewhat
+different address-space layout). This may help for other machines with
+holes in the data segment.
+* Changed the order in which GC_push_roots and friends push things onto
+the mark stack. GC_push_all calls need to come first, since we can't
+necessarily recover if those overflow the mark stack.
+* Some minor cleanups to mostly support the Intel compiler on Linux/IA64.
+
+
+[6.1alpha1]
+===========
+
+* Non-debug, atomic allocations could result in bogus smashed object
+reports with debugging on.
+* Fixed GC_get_register_stack_base (Itanium only) to work around a glibc
+2.2.4 bug.
+* Initial port to HP/UX on Itanium. Thread support and both 32 and 64
+bit ABIs appear to work. Parallel mark support doesn't yet, due to
+some inline assembly code issues. Thread local allocation does appear
+to work.
+* ifdef'ed out glibc2.1/Itanium workaround. I suspect nobody is using
+that combination anymore.
+* Added a patch to make new_gc_alloc.h usable with gcc3.0.
+* Debugged 64-bit support on HP/UX PA-RISC.
+* Turned on dynamic loading support for FreeBSD/ELF.
+* Unregistering of finalizers with debugging allocation was broken.
+* Old finalizers were not returned correctly from GC_debug_register_finalizer.
+* Disabled MPROTECT_VDB for Linux/M68K based on a report that it doesn't work.
+* Cleaned up some statistics gathering code in reclaim.c.
+* Added some support for OpenBSD/ELF/Linux.
+* Added Jakub Jelinek's patch to use dl_iterate_phdr for dynamic library
+traversal to dyn_load.c. Changed it to weakly reference dl_iterate_phdr,
+so that the old code is stilll used with old versions of glibc.
+* Cleaned up feature test macros for various threads packages and
+integrated (partially functional) FreeBSD threads code from Loren Rittle.
+It's likely that the cleanup broke something, since it touched lots of
+code. It's also likelly that it fixed some unreported bugs in the
+less common thread implementations, since some of the original code
+didn't stand up to close scrutiny. Support for the next pthreads
+implementation should be easier to add.
+
+
+[6.0]
+=====
+
+* Two more bug fixes for KEEP_BACK_PTRS and DBG_HDRS_ALL.
+* Fixed a stack clearing problem that resulted in SIGILL with a
+misaligned stack pointer for multi-threaded SPARC builds.
+* Integrated another HURD patch.
+
+
+[6.0alpha9]
+===========
+
+* added README.macros.
+* Made gc.mak a symbolic link to work around winzip's tendency to ignore
+hard links.
+* Simplified the setting of NEED_FIND_LIMIT in os_dep.c, possibly breaking
+it on untested platforms.
+* Integrated initial GNU HURD port.
+* A few more fixes for Digital Mars compiler (Walter Bright).
+* Fixed gcc version recognition. Renamed OPERATOR_NEW_ARRAY to
+GC_OPERATOR_NEW_ARRAY. Changed GC_OPERATOR_NEW_ARRAY to be the default.
+It can be overridden with -DGC_NO_OPERATOR_NEW_ARRAY.
+* Changed the byte size to free-list mapping in thread local allocation
+so that size 0 allocations are handled correctly.
+* Fixed Linux/MIPS stackbottom for new toolchain.
+* Changed finalization registration to invoke GC_oom_fn when it runs out
+of memory.
+* Removed lvalue cast in finalize.c. This caused some debug configurations
+not to build with some non-gcc compilers.
+
+
+[6.0alpha8]
+===========
+
+* Changed GC_debug_malloc_replacement and GC_debug_realloc_replacement
+so that they compile under Irix.
+* Updated powerpc_macosx_mach_dep.s so that it works if the collector
+is in a dynamic library.
+* Transformed README.debugging into debugging.html, updating and
+expanding it in the process. Added gcdescr.html and tree.html
+from the web site to the GC distribution.
+* Fixed several problems related to PRINT_BLACK_LIST. This involved
+restructuring some of the marker macros.
+* Fixed some problems with the sizing of objects with debug information.
+Finalization was broken KEEP_BACK_PTRS or PRINT_BLACK_LIST. Reduced the
+object size with SHORT_DEBUG_HDRS by another word.
+* The "Needed to allocate blacklisted ..." warning had inadvertently
+been turned off by default, due to a buggy test in allchblk.c. Turned
+it back on.
+* Removed the marker macros to deal with 2 pointers in interleaved fashion.
+They were messy and the performance improvement seemed minimal. We'll
+leave such scheduling issues to the compiler.
+* Changed Linux/PowerPC test to also check for __powerpc__ in response
+to a discussion on the gcc mailing list.
+* Removed the "static" from the jmp_buf
+declaration in GC_generic_push_regs. This was causing problems in
+systems that register all of their own roots. It looks far more correct
+to me without the "static" anyway.
+* Fixed several problems with thread local allocation of pointer-free or
+typed objects. The collector was reclaiming thread-local free lists, since
+it wasn't following the link fields.
+* There was apparently a long-standing race condition related to
+multi-threaded incremental collection. A collection could be started and
+a thread stopped between the memory unprotect system call and the setting of
+the corresponding dirt bit. I believe this did not affect Solaris or PCR,
+which use a different dirty-bit implementation. Fixed this by installing
+signal handlers with sigaction instead of signal, and disabling the thread
+suspend signal while in the write-protect handler. (It is unclear
+whether this scenario ever actually occurred. I found it while tracking
+down the following:)
+* Incremental collection did not cooperate correctly with the PARALLEL_MARK
+implementation of GC_malloc_many or the local_malloc primitives. It still
+doesn't work well, but it shouldn't lose memory anymore.
+* Integrated some changes from the gcc source tree that I had previously
+missed.
+* Added Makefile.direct as a copy of the default Makefile, which would
+normally be overwritten if configure is run.
+* Changed the gc.tar target in Makefile.direct to embed the version number
+in the gc directory name. This will affect future tar file distributions.
+* Changed the Irix dynamic library finding code to no longer try to
+eliminate writable text segments under Irix6.x, since that is probably no
+longer necessary, and can apparently be unsafe on occasion.
+* GC_cleanup with GC_DEBUG enabled passed a real object base address to
+GC_debug_register_finalizer_ignore_self, which expected a pointer past the
+debug header. Call GC_register_finalizer_ignore_self instead, even with
+debugging enabled.
+* The collector didn't build with call chain saving enabled but NARGS=0.
+* Fixed up the GNU-style build files enough so that they work in some
+obvious cases.
+* Added initial port to Digital Mars compiler for win32.
+
+
+[6.0alpha7]
+===========
+
+* Added GC_finalizer_notifier. Fixed GC_finalize_on_demand. (The variable
+actually wasn't being tested at the right points. The build-time flag
+was.)
+* Added Tom Tromey's S390 Linux patch.
+* Added code to push GC_finalize_now in GC_push_finalizer_structures.
+* Added GC_push_gc_structures() to push all GC internal roots.
+* Integrated some FreeBSD changes from Matthew Flatt.
+* It looks like USRSTACK is not always correctly defined under Solaris.
+Hacked gcconfig.h to attempt to work around the problem. The result
+is not well tested.
+* Added Ji-Yong Chung's win32 threads and C++ fixes.
+* Arranged for hpux_test_and_clear.s to no longer be needed or built.
+It was causing build problems with gas, and it's not clear this is
+better than the pthreads alternative on this platform.
+* Some MINGW32 fixes from Hubert Garavel.
+* Added Initial Hitachi SH4 port from Kaz Kojima.
+* Ported thread-local allocation and parallel mark code to HP/UX on PA_RISC.
+* Made include/gc_mark.h more public and separated out the really private
+pieces. This is probably still not quite sufficient for clients that
+want to supply their own kind of type information. But it's a start.
+This involved lots of identifier renaming to make it namespace clean.
+* Added GC_dont_precollect for clients that need complete control over
+the root set.
+* GC_is_visible didn't do the right thing with gcj objects. (Not that
+many people are likely to care, but ...)
+* Don't redefine read with GC_USE_LD_WRAP.
+* Initial port to LINUX/HP_PA. Incremental collection and threads are not
+yet supported. (Incremental collection should work if you have the
+right kernel. Threads may work with a sufficiently patched pthread
+library.)
+* Changed gcconfig.h to recognize __i386__ as an alternative to i386 in
+many places.
+* Made win32_threads.c more tolerant of detaching a thread that it didn't
+know about.
+* Added Makefile.am and configure.in from gcc to the distribution, with
+minimal changes. For the moment, those are just placeholders. In the
+future, we're planning to switch to a GNU-style build environment for
+Un*x-like systems, though the old Makefile will remain as a backup.
+* Turned off STUBBORN_ALLOC by default, and added it back as a Makefile
+option.
+* Redistributed some functions between malloc.c and mallocx.c, so that
+simple statically linked apps no longer pull in mallocx.o.
+* Changed large object allocation to clear the first and last few words
+of each block before releasing the lock. Otherwise the marker could see
+objects with nonsensical type descriptors.
+* Fixed a couple of subtle problems that could result in not recognizing
+interior pointers from the stack. (I believe these were introduced
+in 6.0alpha6.)
+* GC_debug_free_inner called GC_free, which tried to reacquire the
+allocator lock, and hence deadlocked. (DBG_HDRS_ALL probably never worked
+with threads.)
+* Fixed several problems with back traces. Accidental references to a free
+list could cause the free list pointer to be overwritten by a back pointer.
+There seemed to be some problems with the encoding of root and finalizer
+references.
+
+
+[6.0alpha6]
+===========
+
+* Changed the definition of DATASTART on ALPHA and IA64, where data_start
+and __data_start are not defined by earlier versions of glibc. This might
+need to be fixed on other platforms as well.
+* Changed the way the stack base and backing store base are found on IA64.
+This should now remain reliable on future kernels. But since it relies
+on /proc, it will no longer work in the simulated NUE environment.
+* Made the call to random() in dbg_mlc.c with -DKEEP_BACK_PTRS dependent
+on the OS. On non-Unix systems, rand() should be used instead. Handled
+small RAND_MAX.
+* Fixed the cord make rules to create the cord subdirectory, if necessary.
+* Changed fo_object_size calculation in finalize.c. Turned finalization
+of non-heap object into a no-op. Removed anachronism from GC_size()
+implementation.
+* Changed GC_push_dirty call in solaris_threads.c to GC_push_selected.
+It was missed in a previous renaming.
+* Arranged to not not mask SIGABRT in linux_threads.c.
+* Added GC_no_dls hook for applications that want to register their own
+roots.
+* Integrated Kjetil Matheussen's Amiga changes.
+* Added FREEBSD_STACKBOTTOM. Changed the X86/FreeBSD port to use it.
+* Added pthread_detach interception for platforms supported by linux_threads.c
+and irix_threads.c.
+* Changed the USE_MMAP code to check for the case in which we got the
+high end of the address space, i.e. mem_ptr + mem_sz == 0. It appears
+that this can happen under Solaris 7. It seems to be allowed by what
+I would claim is an oversight in the mmap specification.
+* Cleanup of linux_threads.c. Some code was originally cloned from
+irix_threads.c and now unnecessary. Some comments were obviously wrong.
+* (Mostly) fixed a longstanding problem with setting of dirty bits from
+a signal handler. In the presence of threads, dirty bits could get lost,
+since the etting of a bit in the bit vector was not atomic with respect
+to other updates. The fix is 100% correct only for platforms for which
+GC_test_and_set is defined. The goal is to make that all platforms with
+thread support. Matters only if incremental GC and threads are both
+enabled.
+* made GC_all_interior_pointers (a.k.a. ALL_INTERIOR_POINTERS) an
+initialization time, instead of build-time option. This is a
+nontrivial, high risk change. It should slow down the code measurably
+only if MERGE_SIZES is not defined, which is a very nonstandard
+configuration.
+* Added doc/README.environment, and implemented what it describes. This
+allows a number of additional configuration options to be set through
+the environment. It documents a few previously undocumented options.
+* Integrated Eric Benson's leak testing improvements.
+* Removed the option to throw away the beginning of each page (DISCARD_WORDS).
+This became less and less useful as processors enforce stricter alignment.
+And it hadn't been tested in ages, and was thus probably broken anyway.
+
+
+[6.0alpha5]
+===========
+
+* Changed the definition of GC_pause in linux_threads.c to use a volatile
+asm. Some versions of gcc apparently optimize away writes to local volatile
+variables. This caused poor locking behavior starting at about
+4 processors.
+* Added GC_start_blocking(), GC_end_blocking() calls and wrapper for sleep
+to linux_threads.c.
+The first two calls could be used to generally avoid sending GC signals to
+blocked threads, avoiding both premature wakeups and unnecessary overhead.
+* Fixed a serious bug in thread-local allocation. At thread termination,
+GC_free could get called on small integers. Changed the code for thread
+termination to more efficiently return left-over free-lists.
+* Integrated Kjetil Matheussen's BeOS support.
+* Rearranged the directory structure to create the doc and tests
+subdirectories.
+* Sort of integrated Eric Benson's patch for OSF1. This provided basic
+OSF1 thread support by suitably extending hpux_irix_threads.c. Based
+on earlier email conversations with David Butenhof, I suspect that it
+will be more reliable in the long run to base this on linux_threads.c
+instead. Thus I attempted to patch up linux_threads.c based on Eric's code.
+The result is almost certainly broken, but hopefully close enough that
+someone with access to a machine can pick it up.
+* Integrated lots of minor changes from the NetBSD distribution. (These
+were supplied by David Brownlee. I'm not sure about the original
+authors.)
+* Hacked a bit more on the HP/UX thread-support in linux_threads.c. It
+now appears to work in the absence of incremental collection. Renamed
+hpux_irix_threads.c back to irix_threads.c, and removed the attempt to
+support HPUX there.
+* Changed gc.h to define _REENTRANT in cases in which it should already
+have been defined. It is still safer to also define it on the command
+line.
+
+
+[6.0alpha4]
+===========
+
+* Moved up the detection of mostly full blocks to the initiation of the
+sweep phase. This eliminates some lock contention in the PARALLEL_MARK case,
+as multiple threads try to look at mostly full blocks concurrently.
+* Restored the code in GC_malloc_many that grabs a prefix of the global
+free list. This avoids the case in which every GC_malloc_many call
+tries and fails to allocate a new heap block, and the returns a single
+object from the global free list.
+* Some minor fixes in new_hblk.c. (Attempted to build free lists in order
+of increasing addresses instead of decreasing addresses for cache performance
+reasons. But this seems to be only a very minor gain with -DEAGER_SWEEP,
+and a loss in other cases. So the change was backed out.)
+* Fixed some of the documentation.
+* Fixed the Linux USE_PROC_FOR_LIBRARIES code to deal with apps that perform
+large numbers of mmaps. Also fixed that code to
+deal with short reads.
+* Added GC_get_total_bytes().
+* Fixed leak detection mode to avoid spurious messages under linuxthreads.
+(This should also now be easy for the other supported threads packages.
+But the code is tricky enough that I'm hesitant to do it without being able
+to test. Everything allocated in the GC thread support itself should be
+explicitly deallocated.)
+* Made it possible (with luck) to redirect malloc to GC_local_malloc.
+
+
+[6.0alpha3]
+===========
+
+* Fixed the /proc/self/maps code to not seek, since that apparently is not
+reliable across all interesting kernels.
+* Fixed some compilation problems in the absence of PARALLEL_MARK
+(introduced in alpha2).
+* Fixed an algorithmic problem with PARALLEL_MARK. If work needs to
+be given back to the main mark "stack", the BOTTOM entries of the local
+stack should be given away, not the top ones. This has substantial
+performance impact, especially for > 2 processors, from what I can tell.
+* Extracted gc_lock.h from gc_priv.h. This should eventually make it a
+bit easier to avoid including gc_priv.h in clients.
+* Moved all include files to include/ and removed duplicate links to the
+same file. The old scheme was a bad idea because it was too easy to get the
+copies out of sync, and many systems don't support hard links.
+Unfortunately, it's likely that I broke some of the non-Unix Makefiles in
+the process, although I tried to update them appropriately.
+* Removed the partial support for a copied nursery. It's not clear that
+this would be a tremendous win, since we don't consistently lose to
+generational copying collectors. And it would significantly complicate
+many things. May be reintroduced if/when it really turns out to win.
+* Removed references to IRIX_JDK_THREADS, since I believe there never
+were and never will be any clients.
+* Added some code to linux_threads.c to possibly support HPUX threads
+using the Linux code. Unfortunately, it doesn't work yet, and is
+currently disabled.
+* Added support under Linux/X86 for saving the call chain, both in (debug)
+objects for client debugging, and in GC_arrays._last_stack for GC
+debugging. This was previously supported only under Solaris. It is
+not enabled by default under X86, since it requires that code be compiled
+to explicitly gave frame pointers on the call stack. (With gcc this
+currently happens by default, but is often turned off explicitly.)
+To turn it on, define SAVE_CALL_CHAIN.

+* Added USE_MARK_BYTES to reduce the need for compare-and-swap on platforms
+for which that's expensive.
+* Fixed a locking bug ib GC_gcj_malloc and some locking assertion problems.
+* Added a missing volatile to OR_WORD and renamed the parameter to
+GC_compare_and_swap so it's not a C++ reserved word.
+* Changed Linux dynamic library registration code to look at /proc/self/maps
+instead of the rld data structures when REDIRECT_MALLOC is defined.
+Otherwise some of the rld data data structures may be prematurely garbage
+collected.
+* Fixed USE_LD_WRAP a bit more, so it should now work without threads.
+* Renamed XXX_THREADS macros to GC_XXX_THREADS for namespace correctness.
+Temporarily added some backward compatibility definitions. Renamed
+USE_LD_WRAP to GC_USE_LD_WRAP.
+* Many MACOSX POWERPC changes, some additions to the gctest output, and
+a few minor generic bug fixes.
+
+
+[6.0alpha1]
+===========
+
+* Added HP/PA prefetch support.
+* Added -DDBG_HDRS_ALL and -DSHORT_DBG_HDRS to reduce the cost and improve
+the reliability of generating pointer backtrace information, e.g. in
+the Bigloo environment.
+* Added parallel marking support (-DPARALLEL_MARK). This currently
+works only under IA32 and IA64 Linux, but it shouldn't be hard to adapt
+to other platforms. This is intended to be a lighter-weight (less
+new code, probably not as scalable) solution than the work by Toshio Endo
+et al, at the University of Tokyo. A number of their ideas were
+reused, though the code wasn't, and the underlying data structure
+is significantly different. In particular, we keep the global mark
+stack as a single shared data structure, but most of the work is done
+on smaller thread-local mark stacks.
+* Changed GC_malloc_many to be cheaper, and to require less mutual exclusion
+with -DPARALLEL_MARK.
+* Added full support for thread local allocation under Linux
+(-DTHREAD_LOCAL_ALLOC). This is a thin veneer on GC_malloc_many, and
+should be easily portable to other platforms, especially those that
+support pthreads.
+* CLEAR_DOUBLE was not always getting invoked when it should have been.
+* GC_gcj_malloc and friends used different out of memory handling than
+everything else, probably because I forgot about one when I implemented
+the other. They now both call GC_oom_fn(), not GC_oom_action().
+* Integrated Jakub Jelinek's fixes for Linux/SPARC.
+* Moved GC_objfreelist, GC_aobjfreelist, and GC_words_allocd out of
+GC_arrays, and separately registered the first two as excluded roots.
+This makes code compiled with gc_inl.h less dependent on the
+collector version. (It would be nice to remove the inclusion of
+gc_priv.h by gc_inl.h completely, but we're not there yet. The
+locking definitions in gc_priv.h are still referenced.)
+This change was later conditioned on SEPARATE_GLOBALS, which
+is not defined by default, since it involves a performance hit.
+* Register GC_obj_kinds separately as an excluded root region. The
+attempt to register it with GC_arrays was usually failing. (This wasn't
+serious, but seemed to generate some confusion.)
+* Moved backptr.h to gc_backptr.h.
+
+
+[5.4]
+=====
+
+* Fixed a typo that prevented compilation with -DUSE_3DNOW_PREFETCH.
+* Fixed GC_is_thread_stack in solaris_threads.c. It forgot to return a value
+in the common case.
+* Fixed another silly syntax problem in GC_double_descr.
+* Fixed a GC_gcj_malloc bug: It tended to release the allocator lock twice.
+
+
+[5.3]
+=====
+
+* Fixed _end declaration for OSF1.
+* There were lots of spurious leak reports in leak detection mode, caused
+by the fact that some pages were not being swept, and hence unmarked
+objects weren't making it onto free lists. (This bug dated back to 5.0.)
+* Fixed a typo in the liblinuxgc.so Makefile rule.
+* Added the GetExitCodeThread to Win32 GC_stop_world to (mostly) work
+around a Windows 95 GetOpenFileName problem.
+
+
+[5.2]
+=====
+
+* dyn_load.c declared GC_scratch_last_end_ptr as an extern even if it
+was defined as a macro. This prevented the collector from building on
+Irix.
+* We quietly assumed that indirect mark descriptors were never 0.
+Our own typed allocation interface violated that. This could result
+in segmentation faults in the marker with typed allocation.
+* Fixed a _DUSE_MUNMAP bug in the heap block allocation code.
+* Taught the collector about VC++ handling array operator new.
+* The two copies of gc_hdrs.h had diverged. Made one a link to the other
+again.
+
+
+[5.1]
+=====
+
+* Fixed a gc.h header bug which showed up under Irix.
+* Fixed a typo in GC_double_descr in typd_mlc.c.
+This probably could result in objects described by array descriptors not
+getting traced correctly.
+* The block nearly full tests in reclaim.c were not correct for 64 bit
+environments. This could result in unnecessary heap growth under unlikely
+conditions.
+
+
+[5.0]
+=====
+
+* Fixed threadlibs.c for linux threads. -DUSE_LD_WRAP was broken and
+-ldl was omitted. Fixed Linux stack finding code to handle
+-DUSE_LD_WRAP correctly.
+* Added MSWIN32 exception handler around marker, so that the collector
+can recover from root segments that are unmapped during the collection.
+This caused occasional failures under Windows 98, and may also be
+an issue under Windows NT/2000.
+
+
+[5.0alpha7]
+===========
+
+* -DREDIRECT_MALLOC was broken in alpha6. Fixed.
+* Cleaned up gc_ccp.h slightly, thus also causing the HP C++ compiler to
+accept it.
+* Removed accidental reference to dbg_mlc.c, which caused dbg_mlc.o to be
+linked into every executable.
+* Added PREFETCH to bitmap marker. Changed it to use the header cache.
+* GC_push_marked sometimes pushed one object too many, resulting in a
+segmentation fault in GC_mark_from_mark_stack. This was probably an old
+bug. It finally showed up in gctest on win32.
+* Gc_priv.h erroneously #defined GC_incremental to be TRUE instead of FALSE
+when SMALL_CONFIG was defined. This was no doubt a major performance bug for
+the default win32 configuration.
+* Removed -DSMALL_CONFIG from NT_MAKEFILE. It seemed like an anachronism now
+that the average PC has 64MB or so.
+* Integrated Bryce McKinley's patches for linux threads and dynamic loading
+from the libgcj tree. Turned on dynamic loading support for Linux/PPC.
+* Changed the stack finding code to use environ on HP/UX. This should
+probably be done on other platforms, too. Since I can't test those, that'll
+wait until after 5.0.
+
+
+[5.0alpha6]
+===========
+
+* GC_malloc_explicitly_typed and friends sometimes failed to
+initialize first word.
+* Added allocation routines and support in the marker for mark descriptors
+in a type structure referenced by the first word of an object. This was
+introduced to support gcj, but hopefully in a way that makes it
+generically useful.
+* Added GC_requested_heapsize, and inhibited collections in non-incremental
+mode if the actual used heap size is less than what was explicitly
+requested.
+* The Solaris pthreads version of GC_pthread_create didn't handle a NULL
+attribute pointer. Solaris thread support used the wrong default thread
+stack size.
+* Changed PUSH_CONTENTS macro to no longer modify first parameter.
+This usually doesn't matter, but it was certainly an accident waiting
+to happen ...
+* Added GC_register_finalizer_no_order and friends to gc.h. They're
+needed by Java implementations.
+* Integrated a fix for a win32 deadlock resulting from clock() calling
+malloc.
+* Integrated Hiroshi Kawashima's port to Linux/MIPS. This was designed
+for a handheld platform, and may or may not be sufficient for other
+machines.
+* Fixed a va_arg problem with the %c specifier in cordprnt.c. It appears
+that this was always broken, but recent versions of gcc are the first to
+report the (statically detectable) bug.
+* Added an attempt at a more general solution to dlopen races/deadlocks.
+GC_dlopen now temporarily disables collection. Still not ideal, but ...
+* Added -DUSE_I686_PREFETCH, -DUSE_3DNOW_PREFETCH, and support for IA64
+prefetch instructions. May improve performance measurably, but I'm not
+sure the code will run correctly on processors that don't support the
+instruction. Won't build except with very recent gcc.
+* Added caching for header lookups in the marker. This seems to result
+in a barely measurable performance gain. Added support for interleaved
+lookups of two pointers, but unconfigured that since the performance
+gain is currently near zero, and it adds to code size.
+* Changed Linux DATA_START definition to check both data_start and
+__data_start, since nothing else seems to be portable.
+* Added -DUSE_LD_WRAP to optionally take advantage of the GNU ld function
+wrapping mechanism. Probably currently useful only on Linux.
+* Moved some variables for the scratch allocator into GC_arrays.
+* Fixed a win32 threads bug that caused the collector to not look for
+interior pointers from one of the thread stacks without
+ALL_INTERIOR_POINTERS.
+* Added Mingw32 support.
+* Changed the alpha port to use the generic register scanning code instead
+of alpha_mach_dep.s. Alpha_mach_dep.s doesn't look for pointers in fp
+registers, but gcc sometimes spills pointers there. Changed the IA64 code to
+do something similar for similar reasons.
+
+
+[5.0alpha4]
+===========
+
+* Added protection fault handling patch for Linux/M68K from Fergus
+Henderson and Roman Hodek.
+* Removed the tests for SGI_SOURCE in new_gc_alloc.h. This was causing that
+interface to fail on nonSGI platforms.
+* Changed the Linux stack finding code to use /proc, after changing it
+to use HEURISTIC1.
+* Added HP/UX incremental GC support and HP/UX 11 thread support.
+Thread support is currently still flakey.
+* Added basic Linux/IA64 support.
+* Integrated Anthony Green's PicoJava support.
+* Integrated Scott Ananian's StrongARM/NetBSD support.
+* Fixed some fairly serious performance bugs in the incremental
+collector. These have probably been there essentially forever.
+(Mark bits were sometimes set before scanning dirty pages.
+The reclaim phase unnecessarily dirtied full small object pages.)
+* Changed the reclaim phase to ignore nearly full pages to avoid
+touching them.
+* Limited GC_black_list_spacing to roughly the heap growth increment.
+* Changed full collection triggering heuristic to decrease full GC
+frequency by default, but to explicitly trigger full GCs during
+heap growth. This doesn't always improve things, but on average it's
+probably a win.
+* GC_debug_free(0, ...) failed.
+
+
+[5.0alpha3]
+===========
+
+* Added some highly incomplete code to support a copied young generation.
+Comments on nursery.h are appreciated.
+* Changed -DFIND_LEAK, -DJAVA_FINALIZATION, and -DFINALIZE_ON_DEMAND,
+so the same effect could be obtained with a runtime switch. This is
+a step towards standardizing on a single dynamic GC library.
+* Significantly changed the way leak detection is handled, as a consequence
+of the above.
+
+
+[5.0alpha2]
+===========
+
+* Fixed bugs introduced in alpha1 (OpenBSD & large block initialization).
+* Added -DKEEP_BACK_PTRS and backptr.h interface. (The implementation
+idea came from Al Demers.)
+
+
+[5.0alpha1]
+===========
+
+* Reworked large block allocator. Now uses multiple doubly linked free
+lists to approximate best fit.
+* Changed heap expansion heuristic. Entirely free blocks are no longer
+counted towards the heap size. This seems to have a major impact on
+heap size stability; the old version could expand the heap way too
+much in the presence of large block fragmentation.
+* added -DGC_ASSERTIONS and some simple assertions inside the collector.
+This is mainlyt for collector debugging.
+* added -DUSE_MUNMAP to allow the heap to shrink. Supported on only
+a few UNIX-like platforms for now.
+* added GC_dump_regions() for debugging of fragmentation issues.
+* Changed PowerPC pointer alignment under Linux to 4.
+* Changed the Linux/Alpha port to walk the data segment backwards until
+it encounters a SIGSEGV. The old way to find the start of the data
+segment broke with a recent release.
+* cordxtra.c needed to call GC_REGISTER_FINALIZER instead of
+GC_register_finalizer, so that it would continue to work with GC_DEBUG.
+* allochblk sometimes cleared the wrong block for debugging purposes
+when it dropped blacklisted blocks. This could result in spurious
+error reports with GC_DEBUG.
+* added MACOS X Server support.
+* Changed the Solaris threads code to ignore stack limits > 8 MB with
+a warning. Empirically, it is not safe to access arbitrary pages
+in such large stacks. And the dirty bit implementation does not
+guarantee that none of them will be accessed.
+* Integrated Martin Tauchmann's Amiga changes.
+* Integrated James Dominy's OpenBSD/SPARC port.
+
+
+[4.14]
+======
+
+* changed STACKBOTTOM for DJGPP.
+
+
+[4.14alpha2]
+============
+
+* -DSMALL_CONFIG did not work reliably with large (> 4K) pages.
+Recycling the mark stack during expansion could result in a size
+zero heap segment, which confused things. (This was probably also an
+issue with the normal config and huge pages.)
+* Did more work to make sure that callee-save registers were scanned
+completely, even with the setjmp-based code. Added USE_GENERIC_PUSH_REGS
+macro to facilitate testing on machines I have access to.
+* Added code to explicitly push register contents for win32 threads.
+This seems to be necessary.
+
+
+[4.14alpha1]
+============
+
+* Fixed GC_print_source_ptr to not use a prototype.
+* generalized CYGWIN test.
+* gc::new did the wrong thing with PointerFreeGC placement.
+* In the ALL_INTERIOR_POINTERS (default) case, some callee-save register
+values could fail to be scanned if the register was saved and
+reused in a GC frame. This showed up in verbose mode with gctest
+compiled with an unreleased SGI compiler. I vaguely recall an old
+bug report that may have been related. The bug was probably quite old.
+(The problem was that the stack scanning could be deferred until
+after the relevant frame was overwritten, and the new save location
+might be outside the scanned area. Fixed by more eager stack scanning.)
+* PRINT_BLACK_LIST had some problems. A few source addresses were garbage.
+* Replaced Makefile.dj and added -I flags to cord make targets.
+* GC_try_to_collect was broken with the non-incremental collector.
+* gc_cleanup destructors could pass the wrong address to
+GC_register_finalizer_ignore_self in the presence of multiple
+inheritance.
+* Changed PowerPC Linux stack finding code.
+
+
+[4.13]
+======
+
+* Fixed a crucial bug in the Watcom port. There was a redundant declaration
+of GC_push_one in gc_priv.h.
+* Added FINALIZE_ON_DEMAND.
+* Fixed some pre-ANSI cc problems in test.c.
+* Removed getpagesize() use for Solaris. It seems to be missing in one
+or two versions.
+* Fixed bool handling for SPARCCompiler version 4.2.
+* Fixed some files in include that had gotten unlinked from the main
+copy.
+* Some RS/6000 fixes (missing casts).
+* Fixed several problems in GC_debug_realloc, affecting mostly the
+FIND_LEAK case.
+* GC_exclude_static_roots contained a buggy unsigned comparison to
+terminate a loop.
+* CORD_str failed if the substring occurred at the last possible position.
+(Only affects cord users.)
+* Fixed Linux code to deal with RedHat 5.0 and integrated Peter Bigot's
+os_dep.c code for dealing with various Linux versions.
+* Added workaround for Irix pthreads sigaction bug and possible signal
+misdirection problems.
+Since alpha1:
+* Changed RS6000 STACKBOTTOM.
+* Integrated Patrick Beard's Mac changes.
+* Alpha1 didn't compile on Irix m.n, m < 6.
+* Replaced Makefile.dj with a new one from Gary Leavens.
+* Added Andrew Stitcher's changes to support SCO OpenServer.
+* Added PRINT_BLACK_LIST, to allow debugging of high densities of false
+pointers.
+* Added code to debug allocator to keep track of return address
+in GC_malloc caller, thus giving a bit more context.
+* Changed default behavior of large block allocator to more
+aggressively avoid fragmentation. This is likely to slow down the
+collector when it succeeds at reducing space cost.
+* Integrated Fergus Henderson's CYGWIN32 changes. They are untested,
+but needed for newer versions.
+* USE_MMAP had some serious bugs. This caused the collector to fail
+consistently on Solaris with -DSMALL_CONFIG.
+* Added Linux threads support.
+* Fixed more Linux threads problems.
+* Changed default GC_free_space_divisor to 3 with new large block allocation.
+* More CYGWIN32 fixes.
+* Integrated Tyson-Dowd's Linux-M68K port.
+* Minor HP PA and DEC UNIX fixes from Fergus Henderson.
+* Integrated Christoffe Raffali's Linux-SPARC changes.
+* Allowed for one more GC fixup iteration after a full GC in incremental
+mode. Some quick measurements suggested that this significantly
+reduces pause times even with smaller GC_RATE values.
+* Moved some more GC data structures into GC_arrays. This decreases
+pause times and GC overhead, but makes debugging slightly less convenient.
+* Fixed namespace pollution problem ("excl_table").
+* Made GC_incremental a constant for -DSMALL_CONFIG, hopefully shrinking
+that slightly.
+* Added some win32 threads fixes.
+* Integrated Ivan Demakov and David Stes' Watcom fixes.
+* Various other minor fixes contributed by many people.
+* Renamed config.h to gcconfig.h, since config.h tends to be used for
+many other things.
+* Integrated Matthew Flatt's support for 68K MacOS "far globals".
+* Fixed up some of the dynamic library Makefile targets for consistency
+across platforms.
+* Fixed a USE_MMAP typo that caused out-of-memory handling to fail
+on Solaris.
+* Added code to test.c to test thread creation a bit more.
+* Integrated GC_win32_free_heap.
+* Fixed Solaris 2.7 stack base finding problem. (This may actually
+have been done in an earlier alpha release.)
+Since alpha3:
+* Fixed MSWIN32 recognition test, which interfered with cygwin.
+* Removed unnecessary gc_watcom.asm from distribution. Removed
+some obsolete README.win32 text.
+* Added Alpha Linux incremental GC support.
+Changed Linux signal handler context argument to be a pointer.
+* Took care of some new warnings generated by the 7.3 SGI compiler.
+* Integrated Phillip Musumeci's FreeBSD/ELF fixes.
+* -DIRIX_THREADS was broken with the -o32 ABI (typo in gc_priv.h>
+
+
+[4.12]
+======
+
+* Fixed ElfW definition in dyn_load.c.
+This prevented the dynamic library support from compiling on some
+older ELF Linux systems.
+* Fixed UTS4 port (which I apparently mangled during the integration)
+* "Make C++" failed on Suns with SC4.0, due to a problem with "bool".
+Fixed in gc_priv.h.
+* Added more pieces for GNU win32.
+The current state of things should suffice for at least some
+applications.
+* Changed the out of memory retry count handling. (This matters only
+if GC_max_retries > 0, which is no longer the default.)
+* If a /proc read failed repeatedly, GC_written_pages was not updated
+correctly.
+* Under unlikely circumstances, the allocator could infinite loop in
+an out of memory situation.
+* Fixed a syntactic error in the DJGPP code. Also fixed a test program
+problem with DJGPP.
+* Atomic uncollectable objects were not treated correctly by the
+incremental collector. This resulted in weird log statistics and
+occasional performance problems.
+* Fixed some problems resulting from compilers that don't define
+__STDC__. In this case void * and char * were used inconsistently
+in some cases. (Void * should not have been used at all. If
+you have an ANSI superset compiler that does not define __STDC__,
+please compile with -D__STDC__=0.)
+* Fixed a compilation problem on Irix with -n32 and -DIRIX_THREADS.
+Also fixed some other IRIX_THREADS problems which may or may not have
+had observable symptoms.
+* Fixed an HP PA compilation problem in dyn_load.c.
+* SEGV fault handlers sometimes did not get reset correctly.
+* Added a fix for SOLARIS_THREADS on Intel.
+This probably needs more work to become functional.
+* Fixed struct sigcontext_struct in os_dep.c for compilation under
+Linux 2.1.X.
+* Changed the DJGPP STACKBOTTOM and DATASTART values to those ones suggested.
+These may still not be right, but it is
+it is likely to work more often than what was there before. They may
+even be exactly right.
+* Added a #include <string.h> to test_cpp.cc. This appears to help
+with HP/UX and gcc.
+* Version 4.11 failed to run in incremental mode on recent 64-bit Irix
+kernels. This was a problem related to page unaligned heap segments.
+Changed the code to page align heap sections on all platforms.
+(I had mistakenly identified this as a kernel problem earlier.
+It was not.)
+* Version 4.11 did not make allocated storage executable, except on
+one or two platforms, due to a bug in a #if test.
+* Added sparc_sunos4_mach_dep.s to support Sun's compilers under SunOS4.
+* Added GC_exclude_static_roots.
+* Fixed the object size mapping algorithm. This shouldn't matter,
+but the old code was ugly.
+* Heap checking code could die if one of the allocated objects was
+larger than its base address. (Unsigned underflow problem.)
+* Added RS6000 (AIX) dynamic library support and fixed STACK_BOTTOM.
+* Added Fergus Henderson's patches for improved robustness with large
+heaps and lots of blacklisting.
+* Added Peter Chubb's changes to support Solaris Pthreads, to support
+MMAP allocation in Solaris, to allow Solaris to find dynamic libraries
+through /proc, to add malloc_typed_ignore_off_page, and a few other
+minor features and bug fixes.
+* The Solaris 2 port should not use sbrk. I received confirmation from
+Sun that the use of sbrk and malloc in the same program is not
+supported. The collector now defines USE_MMAP by default on Solaris.
+* Replaced the djgpp makefile with Gary Leavens' version.
+* Fixed MSWIN32 detection test.
+* Added Fergus Henderson's patches to allow putting the collector into
+a DLL under GNU win32.
+* Added Ivan V. Demakov's port to Watcom C on X86.
+* Added Ian Piumarta's Linux/PowerPC port.
+* Added PointerFreeGC to the placement
+options in gc_cpp.h. This is of course unsafe, and may be controversial.
+On the other hand, it seems to be needed often enough that it's worth
+adding as a standard facility.
+
+
+[4.11]
+======
+
+* Rationalized (hopefully) GC_try_to_collect in an incremental collection
+environment. It appeared to not handle a call while a collection was in
+progress, and was otherwise too conservative.
+* Merged GC_reclaim_or_delete_all into GC_reclaim_all to get rid of some
+code.
+* Added Patrick Beard's Mac fixes, with substantial completely untested
+modifications.
+* Fixed the MPROTECT_VDB code to deal with large pages and imprecise
+fault addresses (as on an UltraSPARC running Solaris 2.5). Note that this
+was not a problem in the default configuration, which uses PROC_VDB.
+* The DEC Alpha assembly code needed to restore $gp between calls.
+* The write command for "de" was completely broken for large files.
+I used the easiest portable fix, which involved changing the semantics
+so that f.new is written instead of overwriting f. That's safer anyway.
+* Added README.solaris2 with a discussion of the possible problems of
+mixing the collector's sbrk allocation with malloc/realloc.
+* Changed the data segment starting address for SGI machines. The
+old code failed under IRIX6.
+* Required double word alignment for MIPS.
+* Various minor fixes to remove warnings.
+* Attempted to fix some Solaris threads problems.
+In particular, the collector could try to fork a thread with the
+world stopped as part of GC_thr_init. It also failed to deal with
+the case in which the original thread terminated before the whole
+process did.
+* Added -DNO_EXECUTE_PERMISSION. This has a major performance impact
+on the incremental collector under Irix, and perhaps under other
+operating systems.
+* Added some code to support allocating the heap with mmap. This may
+be preferable under some circumstances.
+* Integrated dynamic library support for HP.
+* Integrated James Clark's win32 threads support, and made a number
+of changes to it. This is still not 100% solid.
+* Integrated Alistair Crooks' support for UTS4 running on an Amdahl
+370-class machine.
+* Fixed a serious bug in explicitly typed allocation. Objects requiring
+large descriptors where handled in a way that usually resulted in
+a segmentation fault in the marker.
+* Added partial support for GNU win32 development.
+* Added optional support for Java-style finalization semantics.
+This is recommended only for Java implementations.
+* GC_malloc_uncollectable faulted instead of returning 0 when out of
+memory.
+* Calls to GC_base before the collector was initialized failed on a
+DEC Alpha.
+* Added base pointer checking to GC_REGISTER_FINALIZER in debugging mode.
+* GC_debug_realloc failed for uncollectable objects.
+* Explicitly typed allocation could crash if it ran out of memory.
+* Added minimal support for a DEC Alpha running Linux.
+* Fixed a problem with allocation of objects whose size overflowed
+ptrdiff_t. (This now fails unconditionally, as it should.)
+* Added the beginning of Irix pthread support.
+* Integrated Xiaokun Zhu's fixes for djgpp 2.01.
+* Added SGI-style STL allocator support (gc_alloc.h).
+* Fixed a serious bug in README.solaris2.
+Multi-threaded programs must include
+gc.h with SOLARIS_THREADS defined.
+* Changed GC_free so it actually deallocates uncollectable objects.
+* Added Linux ELF support for dynamic libraries.
+* Changed the Borland cc configuration so that the assembler is not
+required.
+* Fixed a bug in the C++ test that caused it to fail in 64-bit
+environments.
+
+
+[4.10]
+======
+
+* Fixed a typo around a call to GC_collect_or_expand in alloc.c. It broke
+handling of out of memory.
+
+
+[4.9]
+=====
+
+* More README.debugging fixes.
+* Objects ready for finalization, but not finalized in the same GC
+cycle, could be prematurely collected. This occasionally happened
+in test_cpp.
+* Too little memory was obtained from the system for very large
+objects. That could cause a heap explosion if these objects were
+not contiguous (e.g. under PCR), and too much of them was blacklisted.
+* Due to an improper initialization, the collector was too hesitant to
+allocate blacklisted objects immediately after system startup.
+* Moved GC_arrays from the data into the bss segment by not explicitly
+initializing it to zero. This significantly
+reduces the size of executables, and probably avoids some disk accesses
+on program startup. It's conceivable that it might break a port that I
+didn't test.
+* Fixed EMX_MAKEFILE to reflect the gc_c++.h to gc_cpp.h renaming which
+occurred a while ago.
+
+
+[4.8]
+=====
+
+* Changed a "comment" in a MacOS specific part of mach_dep.c that caused
+gcc to fail on other platforms.
+
+
+[4.7]
+=====
+
+* Fixed some compilation problems with -DCHECKSUMS.
+* Updated some Mac specific files.
+* Fixed a serious bug for machines with non-word-aligned pointers.
+
+
+[4.6]
+=====
+
+* Added Linux ELF support.
+* GC_base crashed if it was called before any other GC_ routines.
+This could happen if a gc_cleanup object was allocated outside the heap
+before any heap allocation.
+* The heap expansion heuristic was not stable if all objects had finalization
+enabled. Fixed finalize.c to count memory in finalization queue and
+avoid explicit deallocation. Changed alloc.c to also consider this count.
+(This is still not recommended. It's expensive if nothing else.)
+* GC_malloc_uncollectable(0) was broken.
+* The collector didn't compile under Linux 1.3.X.
+The current workaround is ugly, but expected to be temporary.
+* Fixed a formatting problem for SPARC stack traces.
+* Fixed some '=='s in os_dep.c that should have been assignments.
+Fortunately these were in code that should never be executed anyway.
+* Fixed the heap block allocator to only drop blacklisted blocks in small
+chunks. Made BL_LIMIT self adjusting. (Both of these were in response
+to heap growth observed by Paul Graham.)
+* Fixed the Metrowerks/68K Mac code to also mark from a6.
+* Significantly updated README.debugging.
+* Fixed some problems with longjmps out of signal handlers, especially under
+Solaris. Added a workaround for the fact that siglongjmp doesn't appear to
+do the right thing with -lthread under Solaris.
+* Added MSDOS/djgpp port.
+* Added "make reserved_namespace" and "make user_namespace". The
+first renames ALL "GC_xxx" identifiers as "_GC_xxx". The second is the
+inverse transformation. Note that doing this is guaranteed to break all
+clients written for the other names.
+* descriptor field for kind NORMAL in GC_obj_kinds with ADD_BYTE_AT_END
+defined should be -ALIGNMENT not WORDS_TO_BYTES(-1). This is
+a serious bug on machines with pointer alignment of less than a word.
+* GC_ignore_self_finalize_mark_proc didn't handle pointers to very near the
+end of the object correctly. Caused failures of the C++ test on a DEC Alpha
+with g++.
+* gc_inl.h still had problems. Partially fixed. Added warnings at the
+beginning to hopefully specify the remaining dangers.
+* Added DATAEND definition to config.h.
+* Fixed some of the .h file organization. Fixed "make floppy".
+
+
+[4.5]
+=====
+
+* Fixed many minor and one major README bugs.
+* Fixed ALPHA/OSF/1 dynamic library support.
+* Added incremental GC support (MPROTECT_VDB) for Linux (with some
+help from Bruno Haible).
+* Altered SPARC recognition tests in gc.h and config.h.
+* Added basic incremental GC support for win32, as implemented by
+Windows NT and Windows 95. GC_enable_incremental is a no-op
+under win32s, which doesn't implement enough of the VM interface.
+* Added -DLARGE_CONFIG.
+* Fixed GC_..._ignore_off_page to also function without
+-DALL_INTERIOR_POINTERS.
+* (Hopefully) fixed RS/6000 port. (Only the test was broken.)
+* Fixed a performance bug in the non-incremental collector running
+on machines supporting incremental collection with MPROTECT_VDB
+(e.g. SunOS 4, DEC AXP). This turned into a correctness bug under
+win32s with win32 incremental collection. (Not all memory protection
+was disabled.)
+* Fixed some ppcr related bit rot.
+* Caused dynamic libraries to be unregistered before re-registering.
+The old way turned out to be a performance bug on some machines.
+* GC_root_size was not properly maintained under MSWIN32.
+* Added -DNO_DEBUGGING and GC_dump.
+* Fixed a couple of bugs arising with SOLARIS_THREADS +
+REDIRECT_MALLOC.
+* Added NetBSD/M68K port.
+* Fixed a serious realloc bug. For certain object sizes, the collector
+wouldn't scan the expanded part of the object.
+
+
+[4.4]
+=====
+
+* ASM_CLEAR_CODE was erroneously defined for HP
+PA machines, resulting in a compile error.
+* Fixed OS/2 Makefile to create a library.
+* Gc_cleanup objects didn't work if they were created on
+the stack. Fixed.
+* One copy of Gc_cpp.h in the distribution was out of
+synch, and failed to document some known compiler
+problems with explicit destructor invocation. Partially
+fixed. There are probably other compilers on which
+gc_cleanup is miscompiled.
+* Fixed Makefile to pass C compiler flags to C++ compiler.
+* Added Mac fixes.
+* Fixed os_dep.c to work around what appears to be
+a new and different VirtualQuery bug under newer
+versions of win32S.
+* GC_non_gc_bytes was not correctly maintained by
+GC_free. Fixed.
+* Added GC_set_max_heap_size.
+* Changed allocation code to ignore blacklisting if it is preventing
+use of a very large block of memory. This has the advantage
+that naive code allocating very large objects is much more
+likely to work. The downside is you might no
+longer find out that such code should really use
+GC_malloc_ignore_off_page.
+* Changed GC_printf under win32 to close and reopen the file
+between calls. FAT file systems otherwise make the log file
+useless for debugging.
+* Added GC_try_to_collect and GC_get_bytes_since_gc. These
+allow starting an abortable collection during idle times.
+This facility does not require special OS support.
+* Added some support for the Borland development environment.
+* Removed a misfeature from checksums.c that caused unexpected
+heap growth.
+* Changed finalize.c to call WARN if it encounters a finalization cycle.
+WARN is defined in gc_priv.h to write a message, usually to stdout.
+In many environments, this may be inappropriate.
+* Renamed NO_PARAMS in gc.h to GC_NO_PARAMS, thus adhering to my own
+naming convention.
+* Added GC_set_warn_proc to intercept warnings.
+* Fixed Amiga port.
+* Fixed a bug in mark.c that could result in an access to unmapped
+memory from GC_mark_from_mark_stack on machines with unaligned
+pointers.
+* Fixed a win32 specific performance bug that could result in scanning of
+objects allocated with the system malloc.
+* Added REDIRECT_MALLOC.
+
+
+[4.3]
+=====
+
+* Fixed SPARC alignment problem with GC_DEBUG.
+* Fixed Solaris threads /proc workaround. The real
+problem was an interaction with mprotect.
+* Incorporated fix from Patrick Beard for gc_c++.h (now gc_cpp.h).
+* Slightly improved allocator space utilization by
+fixing the GC_size_map mechanism.
+* Integrated some Sony News and MIPS RISCos 4.51
+patches.
+* Fixed HP_PA alignment problem.
+* Added GC_same_obj and friends. Changed GC_base
+to return 0 for pointers past the end of large objects.
+Improved GC_base performance with ALL_INTERIOR_POINTERS
+on machines with a slow integer mod operation.
+Added GC_PTR_ADD, GC_PTR_STORE, etc. to prepare
+for preprocessor.
+* changed the default on most UNIX machines to be that
+signals are not disabled during critical GC operations.
+This is still ANSI-conforming, though somewhat dangerous
+in the presence of signal handlers. But the performance
+cost of the alternative is sometimes problematic.
+Can be changed back with a minor Makefile edit.
+* renamed IS_STRING in gc.h, to CORD_IS_STRING, thus
+following my own naming convention. Added the function
+CORD_to_const_char_star.
+* Fixed a gross bug in GC_finalize. Symptom: occasional
+address faults in that function.
+* Added port to ICL DRS6000 running DRS/NX. Restructured
+things a bit to factor out common code, and remove obsolete
+code. Collector should now run under SUNOS5 with either
+mprotect or /proc dirty bits.
+* More bug fixes and workarounds for Solaris 2.X. (These were
+mostly related to putting the collector in a dynamic library,
+which didn't really work before. Also SOLARIS_THREADS
+didn't interact well with dl_open.)
+* Fixed a serious performance bug on the DEC Alpha. The text
+segment was getting registered as part of the root set.
+(Amazingly, the result was still fast enough that the bug
+was not conspicuous.) The fix works on OSF/1, version 1.3.
+Hopefully it also works on other versions of OSF/1 ...
+* Fixed a bug in GC_clear_roots.
+* Fixed a bug in GC_generic_malloc_words_small that broke
+gc_inl.h.
+* Fixed some problems with cord/de under Linux.
+* Fixed some cord problems, notably with CORD_riter4.
+* Added DG/UX port.
+* Added finalization registration routines with weaker ordering
+constraints. (This is necessary for C++ finalization with
+multiple inheritance, since the compiler often adds self-cycles.)
+* Filled the holes in the SCO port.
+* John Ellis' additions to the C++ support: From John:
+* I completely rewrote the documentation in the interface gc_c++.h
+(later renamed gc_cpp.h). I've tried to make it both clearer and more
+precise.
+* The definition of accessibility now ignores pointers from an
+finalizable object (an object with a clean-up function) to itself.
+This allows objects with virtual base classes to be finalizable by the
+collector. Compilers typically implement virtual base classes using
+pointers from an object to itself, which under the old definition of
+accessibility prevented objects with virtual base classes from ever
+being collected or finalized.
+* gc_cleanup now includes gc as a virtual base. This was enabled by
+the change in the definition of accessibility.
+* I added support for operator new[]. Since most compilers
+don't yet support operator new[], it is conditionalized on
+-DOPERATOR_NEW_ARRAY. The code is untested, but its trivial and looks
+correct.
+* The test program test_gc_c++ (later renamed test_cpp.cc)
+tries to test for the C++-specific functionality not tested by the
+other programs.
+* Added unistd.h include to misc.c. (Needed for ppcr.)
+* Added PowerMac port.
+* Fixed "srcdir"-related Makefile problems. Changed things so
+that all externally visible include files always appear in the
+include subdirectory of the source. Made gc.h directly
+includable from C++ code.
+* Changed Intel code to also mark from ebp
+* Renamed C++ related files so they could live in a FAT
+file system.
+* Changed Windows NT Makefile to include C++ support in
+gc.lib. Added C++ test as Makefile target.
+
+
+[4.2]
+=====
+
+* Multiple bug fixes/workarounds in the Solaris threads version.
+(It occasionally failed to locate some register contents for
+marking. It also turns out that thr_suspend and friends are
+unreliable in Solaris 2.3. Dirty bit reads appear
+to be unreliable under some weird
+circumstances. My stack marking code
+contained a serious performance bug. The new code is
+extremely defensive, and has not failed in several CPU
+hours of testing. But no guarantees ...)
+* Added MacOS support.
+* Fixed several syntactic bugs in gc_c++.h and friends. (These
+didn't bother g++, but did bother most other compilers.)
+Fixed gc_c++.h finalization interface.
+* 64 bit alignment for allocated objects was not guaranteed in a
+few cases in which it should have been.
+* Added GC_malloc_atomic_ignore_off_page.
+* Added GC_collect_a_little.
+* Added some prototypes to gc.h.
+* Some other minor bug fixes (notably in Makefile).
+* Fixed OS/2 / EMX port.
+* Fixed AmigaDOS port.
+* Fixed the DATASTART definition under Solaris. There
+was a 1 in 16K chance of the collector missing the first
+64K of static data (and thus crashing).
+* Fixed some blatant anachronisms in the README file.
+* Fixed PCR-Makefile for upcoming PPCR release.
+
+
+[4.1]
+=====
+
+* Changed finalization implementation to guarantee that
+finalization procedures are called outside of the allocation
+lock, making direct use of the interface a little less dangerous.
+MAY BREAK EXISTING CLIENTS that assume finalizers
+are protected by a lock. Since there seem to be few multi-threaded
+clients that use finalization, this is hopefully not much of
+a problem.
+* Fixed a gross bug in CORD_prev.
+* Fixed a bug in blacklst.c that could result in unbounded
+heap growth during startup on machines that do not clear
+memory obtained from the OS (e.g. win32S).
+* Ported de editor to win32/win32S. (This is now the only
+version with a mouse-sensitive UI.)
+* Added GC_malloc_ignore_off_page to allocate large arrays
+in the presence of ALL_INTERIOR_POINTERS.
+* Changed GC_call_with_alloc_lock to not disable signals in
+the single-threaded case.
+* Reduced retry count in GC_collect_or_expand for garbage
+collecting when out of memory.
+* Made uncollectable allocations bypass black-listing, as they
+should.
+* Fixed a bug in typed_test in test.c that could cause (legitimate)
+GC crashes.
+* Fixed some potential synchronization problems in finalize.c
+* Fixed a real locking problem in typd_mlc.c.
+* Worked around an AIX 3.2 compiler feature that results in
+out of bounds memory references.
+* Partially worked around an IRIX5.2 beta problem (which may
+or may not persist to the final release).
+* Fixed a bug in the heap integrity checking code that could
+result in explicitly deallocated objects being identified as
+smashed. Fixed a bug in the dbg_mlc stack saving code
+that caused old argument pointers to be considered live.
+* Fixed a bug in CORD_ncmp (and hence CORD_str).
+* Repaired the OS2 port, which had suffered from bit rot
+in 4.0. Worked around what appears to be CSet/2 V1.0
+optimizer bug.
+* Fixed a Makefile bug for target "c++".
+
+
+[4.0]
+=====
+
+* Added support for Solaris threads (which was possible
+only by reimplementing some fraction of Solaris threads,
+since Sun doesn't currently make the thread debugging
+interface available).
+* Added non-threads win32 and win32S support.
+* (Grudgingly, with suitable muttering of obscenities) renamed
+files so that the collector distribution could live on a FAT
+file system. Files that are guaranteed to be useless on
+a PC still have long names. Gc_inline.h and gc_private.h
+still exist, but now just include gc_inl.h and gc_priv.h.
+* Fixed a really obscure bug in finalization that could cause
+undetected mark stack overflows. (I would be surprised if
+any real code ever tickled this one.)
+* Changed finalization code to dynamically resize the hash
+tables it maintains. (This probably does not matter for well-
+-written code. It no doubt does for C++ code that overuses
+destructors.)
+* Added typed allocation primitives. Rewrote the marker to
+accommodate them with more reasonable efficiency. This
+change should also speed up marking for GC_malloc allocated
+objects a little. See gc_typed.h for new primitives.
+* Improved debugging facilities slightly. Allocation time
+stack traces are now kept by default on SPARC/SUNOS4.
+* Added better support for small heap applications.
+* Significantly extended cord package. Fixed a bug in the
+implementation of lazily read files. Printf and friends now
+have cord variants. Cord traversals are a bit faster.
+* Made ALL_INTERIOR_POINTERS recognition the default.
+* Fixed de so that it can run in constant space, independent
+of file size. Added simple string searching to cords and de.
+* Added the Hull-Ellis C++ interface.
+* Added dynamic library support for OSF/1.
+* Changed argument to GC_expand_hp to be expressed
+in units of bytes instead of heap blocks. (Necessary
+since the heap block size now varies depending on
+configuration. The old version was never very clean.)
+* Added GC_get_heap_size(). The previous "equivalent"
+was broken.
+* Restructured the Makefile a bit.
+
+
+[3.7]
+=====
+
+* Added a workaround for an HP/UX compiler bug.
+* Fixed another stack clearing performance bug. Reworked
+that code once more.
+
+
+[3.6]
+=====
+
+* fixed a bug in the mark stack growth code that was introduced
+in 3.4.
+* fixed Makefile to work around DEC AXP compiler tail recursion
+bug.
+
+
+[3.5]
+=====
+
+* Minor collections now mark from roots only once, if that
+doesn't cause an excessive pause.
+* The stack clearing heuristic was refined to prevent anomalies
+with very heavily recursive programs and sparse stacks.
+* Fixed a bug that prevented mark stack growth in some cases.
+GC_objects_are_marked should be set to TRUE after a call
+to GC_push_roots and as part of GC_push_marked, since
+both can now set mark bits. I think this is only a performance
+bug, but I wouldn't bet on it. It's certainly very hard to argue
+that the old version was correct.
+* Fixed an incremental collection bug that prevented it from
+working at all when HBLKSIZE != getpagesize()
+* Changed dynamic_loading.c to include gc_priv.h before testing
+DYNAMIC_LOADING. SunOS dynamic library scanning
+must have been broken in 3.4.
+* Object size rounding now adapts to program behavior.
+* Added a workaround (provided by Manuel Serrano and
+colleagues) to a long-standing SunOS 4.X (and 3.X) ld bug
+that I had incorrectly assumed to have been squished.
+The collector was broken if the text segment size was within
+32 bytes of a multiple of 8K bytes, and if the beginning of
+the data segment contained interesting roots. The workaround
+assumes a demand-loadable executable. The original may have
+have "worked" in some other cases.
+* Added dynamic library support under IRIX5.
+* Added support for EMX under OS/2.
+
+
+[3.4]
+=====
+
+* Fixed a performance bug in GC_realloc.
+* Updated the amiga port.
+* Added NetBSD and 386BSD ports.
+* Added cord library.
+* Added trivial performance enhancement for
+ALL_INTERIOR_POINTERS. (Don't scan last word.)
+
+
+[3.3]
+=====
+
+* PCR-specific bugs.
+* Missing locking in GC_free, redundant FASTUNLOCK
+in GC_malloc_stubborn, and 2 bugs in
+GC_unregister_disappearing_link.
+* Common symbols allocated by the SunOS4.X dynamic loader
+were not included in the root set.
+* Bug in GC_finalize
+* Merged Amiga port from Jesper Peterson (untested)
+* Merged NeXT port from Thomas Funke (significantly
+modified and untested)
+
+
+[3.2]
+=====
+
+Fixed a serious and not entirely repeatable bug in
+the incremental collector. It appeared only when dirty bit info
+on the roots was available, which is normally only under Solaris.
+It also added GC_general_register_disappearing_link, and some
+testing code. Interface.c disappeared.
+
+
+[3.1]
+=====
+
+* A workaround for a SunOS 4.X SPARC C compiler
+misfeature that caused problems when the collector was turned into
+a dynamic library.
+* A fix for a bug in GC_base that could result in a memory fault.
+* A fix for a performance bug (and several other misfeatures) pointed
+out by Dave Detlefs and Al Dosser.
+* Use of dirty bit information for static data under Solaris 2.X.
+* DEC Alpha/OSF1 support.
+* Incremental collection on more platforms.
+* A more refined heap expansion policy. Less space usage by default.
+* Various minor enhancements to reduce space usage, and to reduce
+the amount of memory scanned by the collector.
+* Uncollectable allocation without per object overhead.
+* More conscientious handling of out-of-memory conditions.
+* Fixed a bug in debugging stubborn allocation.
+* Fixed a bug that resulted in occasional erroneous reporting of smashed
+objects with debugging allocation.
+* Fixed bogus leak reports of size 4096 blocks with FIND_LEAK.
+
+
+[3.0]
+=====
+
+Added generational/incremental collection and stubborn objects.
+
+
+[2.5]
+=====
+
+* Removed an explicit call to exit(1)
+* Fixed calls to GC_printf and GC_err_printf, so the correct number of
+arguments are always supplied. The OS/2 C compiler gets confused if
+the number of actuals and the number of formals differ. (ANSI C
+doesn't require this to work. The ANSI sanctioned way of doing things
+causes too many compatibility problems.)
+
+
+[2.4]
+=====
+
+Added GC_free_space_divisor as a tuning knob, added
+support for OS/2 and linux, and fixed the following bugs:
+* On machines with unaligned pointers (e.g. Sun 3), every 128th word could
+fail to be considered for marking.
+* Dynamic_load.c erroneously added 4 bytes to the length of the data and
+bss sections of the dynamic library. This could result in a bad memory
+reference if the actual length was a multiple of a page. (Observed on
+Sun 3. Can probably also happen on a Sun 4.)
+(Dynamic library handling is still broken on Sun 3s
+under 4.1.1U1, but apparently not 4.1.1. If you have such a machine,
+use -Bstatic.)
+
+
+[2.3]
+=====
+
+* Added ALL_INTERIOR_POINTERS.
+* Missing declaration of etext in the A/UX version.
+* Some PCR root-finding problems.
+* Blacklisting was not 100% effective, because the plausible future
+heap bounds were being miscalculated.
+* GC_realloc didn't handle out-of-memory correctly.
+* GC_base could return a nonzero value for addresses inside free blocks.
+* test.c wasn't really thread safe, and could erroneously report failure
+in a multi-threaded environment. (The locking primitives need to be
+replaced for other threads packages.)
+* GC_CONS was thoroughly broken.
+* On a SPARC with dynamic linking, signals stayed disabled while the
+client code was running.
+
+
+[2.2]
+=====
+
+* GC_realloc could fail to extend the size of the object for certain large
+object sizes.
+* A blatant subscript range error in GC_printf, which unfortunately
+wasn't exercised on machines with sufficient stack alignment constraints.
+* GC_register_displacement did the wrong thing if it was called after
+any allocation had taken place.
+* The leak finding code would eventually break after 2048 byte
+byte objects leaked.
+* interface.c didn't compile.
+* The heap size remained much too small for large stacks.
+* The stack clearing code behaved badly for large stacks, and perhaps
+on HP/PA machines.
+
+
+[2.1]
+=====
+
+* The first stable version since 1.9.
+* Added support for PPCR.
+
+
+[2.0]
+=====
+
+* Introduced a consistent naming convention for collector
+routines and added support for registering dynamic library data segments
+in the standard mark_roots.c. Most of the data structures were revamped.
+The treatment of interior pointers was completely changed. Finalization
+was added. Support for locking was added. Object kinds were added.
+We added a black listing facility to avoid allocating at addresses known
+to occur as integers somewhere in the address space. Much of this
+was accomplished by adapting ideas and code from the PCR collector.
+The test program was changed and expanded.

-
-This has been maintained with varying diligence over the years.
-
-I made an attempt to include recent contributors here. I apologize for any
-omissions.
-
-RECENT UPDATES ARE RECORDED above INSTEAD TO CONFORM TO
-MORE COMMON CONVENTIONS.
-
-
- Version 1.3 and immediately preceding versions contained spurious
-assembly language assignments to TMP_SP. Only the assignment in the PC/RT
-code is necessary. On other machines, with certain compiler options,
-the assignments can lead to an unsaved register being overwritten.
-Known to cause problems under SunOS 3.5 WITHOUT the -O option. (With
--O the compiler recognizes it as dead code. It probably shouldn't,
-but that's another story.)
+[1.4]
+=====
- Version 1.4 and earlier versions used compile time determined values
+* Does not use compile time determined values
for the stack base. This no longer works on Sun 3s, since Sun 3/80s use
a different stack base. We now use a straightforward heuristic on all
machines on which it is known to work (incl. Sun 3s) and compile-time
determined values for the rest. There should really be library calls
to determine such values.
- Version 1.5 and earlier did not ensure 8 byte alignment for objects
-allocated on a sparc based machine.
-
- Version 1.8 added ULTRIX support in gc_private.h.
-
- Version 1.9 fixed a major bug in gc_realloc.
-
- Version 2.0 introduced a consistent naming convention for collector
-routines and added support for registering dynamic library data segments
-in the standard mark_roots.c. Most of the data structures were revamped.
-The treatment of interior pointers was completely changed. Finalization
-was added. Support for locking was added. Object kinds were added.
-We added a black listing facility to avoid allocating at addresses known
-to occur as integers somewhere in the address space. Much of this
-was accomplished by adapting ideas and code from the PCR collector.
-The test program was changed and expanded.
-
- Version 2.1 was the first stable version since 1.9, and added support
-for PPCR.
-
- Version 2.2 added debugging allocation, and fixed various bugs. Among them:
-- GC_realloc could fail to extend the size of the object for certain large object sizes.
-- A blatant subscript range error in GC_printf, which unfortunately
- wasn't exercised on machines with sufficient stack alignment constraints.
-- GC_register_displacement did the wrong thing if it was called after
- any allocation had taken place.
-- The leak finding code would eventually break after 2048 byte
- byte objects leaked.
-- interface.c didn't compile.
-- The heap size remained much too small for large stacks.
-- The stack clearing code behaved badly for large stacks, and perhaps
- on HP/PA machines.
-
- Version 2.3 added ALL_INTERIOR_POINTERS and fixed the following bugs:
-- Missing declaration of etext in the A/UX version.
-- Some PCR root-finding problems.
-- Blacklisting was not 100% effective, because the plausible future
- heap bounds were being miscalculated.
-- GC_realloc didn't handle out-of-memory correctly.
-- GC_base could return a nonzero value for addresses inside free blocks.
-- test.c wasn't really thread safe, and could erroneously report failure
- in a multithreaded environment. (The locking primitives need to be
- replaced for other threads packages.)
-- GC_CONS was thoroughly broken.
-- On a SPARC with dynamic linking, signals stayed diabled while the
- client code was running.
- (Thanks to Manuel Serrano at INRIA for reporting the last two.)
-
- Version 2.4 added GC_free_space_divisor as a tuning knob, added
- support for OS/2 and linux, and fixed the following bugs:
-- On machines with unaligned pointers (e.g. Sun 3), every 128th word could
- fail to be considered for marking.
-- Dynamic_load.c erroneously added 4 bytes to the length of the data and
- bss sections of the dynamic library. This could result in a bad memory
- reference if the actual length was a multiple of a page. (Observed on
- Sun 3. Can probably also happen on a Sun 4.)
- (Thanks to Robert Brazile for pointing out that the Sun 3 version
- was broken. Dynamic library handling is still broken on Sun 3s
- under 4.1.1U1, but apparently not 4.1.1. If you have such a machine,
- use -Bstatic.)
-
- Version 2.5 fixed the following bugs:
-- Removed an explicit call to exit(1)
-- Fixed calls to GC_printf and GC_err_printf, so the correct number of
- arguments are always supplied. The OS/2 C compiler gets confused if
- the number of actuals and the number of formals differ. (ANSI C
- doesn't require this to work. The ANSI sanctioned way of doing things
- causes too many compatibility problems.)
-
- Version 3.0 added generational/incremental collection and stubborn
- objects.
-
- Version 3.1 added the following features:
-- A workaround for a SunOS 4.X SPARC C compiler
- misfeature that caused problems when the collector was turned into
- a dynamic library.
-- A fix for a bug in GC_base that could result in a memory fault.
-- A fix for a performance bug (and several other misfeatures) pointed
- out by Dave Detlefs and Al Dosser.
-- Use of dirty bit information for static data under Solaris 2.X.
-- DEC Alpha/OSF1 support (thanks to Al Dosser).
-- Incremental collection on more platforms.
-- A more refined heap expansion policy. Less space usage by default.
-- Various minor enhancements to reduce space usage, and to reduce
- the amount of memory scanned by the collector.
-- Uncollectable allocation without per object overhead.
-- More conscientious handling of out-of-memory conditions.
-- Fixed a bug in debugging stubborn allocation.
-- Fixed a bug that resulted in occasional erroneous reporting of smashed
- objects with debugging allocation.
-- Fixed bogus leak reports of size 4096 blocks with FIND_LEAK.
-
- Version 3.2 fixed a serious and not entirely repeatable bug in
- the incremental collector. It appeared only when dirty bit info
- on the roots was available, which is normally only under Solaris.
- It also added GC_general_register_disappearing_link, and some
- testing code. Interface.c disappeared.
-
- Version 3.3 fixes several bugs and adds new ports:
-- PCR-specific bugs.
-- Missing locking in GC_free, redundant FASTUNLOCK
- in GC_malloc_stubborn, and 2 bugs in
- GC_unregister_disappearing_link.
- All of the above were pointed out by Neil Sharman
- (neil@cs.mu.oz.au).
-- Common symbols allocated by the SunOS4.X dynamic loader
- were not included in the root set.
-- Bug in GC_finalize (reported by Brian Beuning and Al Dosser)
-- Merged Amiga port from Jesper Peterson (untested)
-- Merged NeXT port from Thomas Funke (significantly
- modified and untested)
-
- Version 3.4:
-- Fixed a performance bug in GC_realloc.
-- Updated the amiga port.
-- Added NetBSD and 386BSD ports.
-- Added cord library.
-- Added trivial performance enhancement for
- ALL_INTERIOR_POINTERS. (Don't scan last word.)
-
- Version 3.5
-- Minor collections now mark from roots only once, if that
- doesn't cause an excessive pause.
-- The stack clearing heuristic was refined to prevent anomalies
- with very heavily recursive programs and sparse stacks.
-- Fixed a bug that prevented mark stack growth in some cases.
- GC_objects_are_marked should be set to TRUE after a call
- to GC_push_roots and as part of GC_push_marked, since
- both can now set mark bits. I think this is only a performance
- bug, but I wouldn't bet on it. It's certainly very hard to argue
- that the old version was correct.
-- Fixed an incremental collection bug that prevented it from
- working at all when HBLKSIZE != getpagesize()
-- Changed dynamic_loading.c to include gc_priv.h before testing
- DYNAMIC_LOADING. SunOS dynamic library scanning
- must have been broken in 3.4.
-- Object size rounding now adapts to program behavior.
-- Added a workaround (provided by Manuel Serrano and
- colleagues) to a long-standing SunOS 4.X (and 3.X?) ld bug
- that I had incorrectly assumed to have been squished.
- The collector was broken if the text segment size was within
- 32 bytes of a multiple of 8K bytes, and if the beginning of
- the data segment contained interesting roots. The workaround
- assumes a demand-loadable executable. The original may have
- have "worked" in some other cases.
-- Added dynamic library support under IRIX5.
-- Added support for EMX under OS/2 (thanks to Ari Huttunen).
-
-Version 3.6:
-- fixed a bug in the mark stack growth code that was introduced
- in 3.4.
-- fixed Makefile to work around DEC AXP compiler tail recursion
- bug.
-
-Version 3.7:
-- Added a workaround for an HP/UX compiler bug.
-- Fixed another stack clearing performance bug. Reworked
- that code once more.
-
-Version 4.0:
-- Added support for Solaris threads (which was possible
- only by reimplementing some fraction of Solaris threads,
- since Sun doesn't currently make the thread debugging
- interface available).
-- Added non-threads win32 and win32S support.
-- (Grudgingly, with suitable muttering of obscenities) renamed
- files so that the collector distribution could live on a FAT
- file system. Files that are guaranteed to be useless on
- a PC still have long names. Gc_inline.h and gc_private.h
- still exist, but now just include gc_inl.h and gc_priv.h.
-- Fixed a really obscure bug in finalization that could cause
- undetected mark stack overflows. (I would be surprised if
- any real code ever tickled this one.)
-- Changed finalization code to dynamically resize the hash
- tables it maintains. (This probably does not matter for well-
- -written code. It no doubt does for C++ code that overuses
- destructors.)
-- Added typed allocation primitives. Rewrote the marker to
- accommodate them with more reasonable efficiency. This
- change should also speed up marking for GC_malloc allocated
- objects a little. See gc_typed.h for new primitives.
-- Improved debugging facilities slightly. Allocation time
- stack traces are now kept by default on SPARC/SUNOS4.
- (Thanks to Scott Schwartz.)
-- Added better support for small heap applications.
-- Significantly extended cord package. Fixed a bug in the
- implementation of lazily read files. Printf and friends now
- have cord variants. Cord traversals are a bit faster.
-- Made ALL_INTERIOR_POINTERS recognition the default.
-- Fixed de so that it can run in constant space, independent
- of file size. Added simple string searching to cords and de.
-- Added the Hull-Ellis C++ interface.
-- Added dynamic library support for OSF/1.
- (Thanks to Al Dosser and Tim Bingham at DEC.)
-- Changed argument to GC_expand_hp to be expressed
- in units of bytes instead of heap blocks. (Necessary
- since the heap block size now varies depending on
- configuration. The old version was never very clean.)
-- Added GC_get_heap_size(). The previous "equivalent"
- was broken.
-- Restructured the Makefile a bit.
-
-Since version 4.0:
-- Changed finalization implementation to guarantee that
- finalization procedures are called outside of the allocation
- lock, making direct use of the interface a little less dangerous.
- MAY BREAK EXISTING CLIENTS that assume finalizers
- are protected by a lock. Since there seem to be few multithreaded
- clients that use finalization, this is hopefully not much of
- a problem.
-- Fixed a gross bug in CORD_prev.
-- Fixed a bug in blacklst.c that could result in unbounded
- heap growth during startup on machines that do not clear
- memory obtained from the OS (e.g. win32S).
-- Ported de editor to win32/win32S. (This is now the only
- version with a mouse-sensitive UI.)
-- Added GC_malloc_ignore_off_page to allocate large arrays
- in the presence of ALL_INTERIOR_POINTERS.
-- Changed GC_call_with_alloc_lock to not disable signals in
- the single-threaded case.
-- Reduced retry count in GC_collect_or_expand for garbage
- collecting when out of memory.
-- Made uncollectable allocations bypass black-listing, as they
- should.
-- Fixed a bug in typed_test in test.c that could cause (legitimate)
- GC crashes.
-- Fixed some potential synchronization problems in finalize.c
-- Fixed a real locking problem in typd_mlc.c.
-- Worked around an AIX 3.2 compiler feature that results in
- out of bounds memory references.
-- Partially worked around an IRIX5.2 beta problem (which may
- or may not persist to the final release).
-- Fixed a bug in the heap integrity checking code that could
- result in explicitly deallocated objects being identified as
- smashed. Fixed a bug in the dbg_mlc stack saving code
- that caused old argument pointers to be considered live.
-- Fixed a bug in CORD_ncmp (and hence CORD_str).
-- Repaired the OS2 port, which had suffered from bit rot
- in 4.0. Worked around what appears to be CSet/2 V1.0
- optimizer bug.
-- Fixed a Makefile bug for target "c++".
-
-Since version 4.1:
-- Multiple bug fixes/workarounds in the Solaris threads version.
- (It occasionally failed to locate some register contents for
- marking. It also turns out that thr_suspend and friends are
- unreliable in Solaris 2.3. Dirty bit reads appear
- to be unreliable under some weird
- circumstances. My stack marking code
- contained a serious performance bug. The new code is
- extremely defensive, and has not failed in several cpu
- hours of testing. But no guarantees ...)
-- Added MacOS support (thanks to Patrick Beard.)
-- Fixed several syntactic bugs in gc_c++.h and friends. (These
- didn't bother g++, but did bother most other compilers.)
- Fixed gc_c++.h finalization interface. (It didn't.)
-- 64 bit alignment for allocated objects was not guaranteed in a
- few cases in which it should have been.
-- Added GC_malloc_atomic_ignore_off_page.
-- Added GC_collect_a_little.
-- Added some prototypes to gc.h.
-- Some other minor bug fixes (notably in Makefile).
-- Fixed OS/2 / EMX port (thanks to Ari Huttunen).
-- Fixed AmigaDOS port. (thanks to Michel Schinz).
-- Fixed the DATASTART definition under Solaris. There
- was a 1 in 16K chance of the collector missing the first
- 64K of static data (and thus crashing).
-- Fixed some blatant anachronisms in the README file.
-- Fixed PCR-Makefile for upcoming PPCR release.
-
-Since version 4.2:
-- Fixed SPARC alignment problem with GC_DEBUG.
-- Fixed Solaris threads /proc workaround. The real
- problem was an interaction with mprotect.
-- Incorporated fix from Patrick Beard for gc_c++.h (now gc_cpp.h).
-- Slightly improved allocator space utilization by
- fixing the GC_size_map mechanism.
-- Integrated some Sony News and MIPS RISCos 4.51
- patches. (Thanks to Nobuyuki Hikichi of
- Software Research Associates, Inc. Japan)
-- Fixed HP_PA alignment problem. (Thanks to
- xjam@cork.cs.berkeley.edu.)
-- Added GC_same_obj and friends. Changed GC_base
- to return 0 for pointers past the end of large objects.
- Improved GC_base performance with ALL_INTERIOR_POINTERS
- on machines with a slow integer mod operation.
- Added GC_PTR_ADD, GC_PTR_STORE, etc. to prepare
- for preprocessor.
-- changed the default on most UNIX machines to be that
- signals are not disabled during critical GC operations.
- This is still ANSI-conforming, though somewhat dangerous
- in the presence of signal handlers. But the performance
- cost of the alternative is sometimes problematic.
- Can be changed back with a minor Makefile edit.
-- renamed IS_STRING in gc.h, to CORD_IS_STRING, thus
- following my own naming convention. Added the function
- CORD_to_const_char_star.
-- Fixed a gross bug in GC_finalize. Symptom: occasional
- address faults in that function. (Thanks to Anselm
- Baird-Smith (Anselm.BairdSmith@inria.fr)
-- Added port to ICL DRS6000 running DRS/NX. Restructured
- things a bit to factor out common code, and remove obsolete
- code. Collector should now run under SUNOS5 with either
- mprotect or /proc dirty bits. (Thanks to Douglas Steel
- (doug@wg.icl.co.uk)).
-- More bug fixes and workarounds for Solaris 2.X. (These were
- mostly related to putting the collector in a dynamic library,
- which didn't really work before. Also SOLARIS_THREADS
- didn't interact well with dl_open.) Thanks to btlewis@eng.sun.com.
-- Fixed a serious performance bug on the DEC Alpha. The text
- segment was getting registered as part of the root set.
- (Amazingly, the result was still fast enough that the bug
- was not conspicuous.) The fix works on OSF/1, version 1.3.
- Hopefully it also works on other versions of OSF/1 ...
-- Fixed a bug in GC_clear_roots.
-- Fixed a bug in GC_generic_malloc_words_small that broke
- gc_inl.h. (Reported by Antoine de Maricourt. I broke it
- in trying to tweak the Mac port.)
-- Fixed some problems with cord/de under Linux.
-- Fixed some cord problems, notably with CORD_riter4.
-- Added DG/UX port.
- Thanks to Ben A. Mesander (ben@piglet.cr.usgs.gov)
-- Added finalization registration routines with weaker ordering
- constraints. (This is necessary for C++ finalization with
- multiple inheritance, since the compiler often adds self-cycles.)
-- Filled the holes in the SCO port. (Thanks to Michael Arnoldus
- <chime@proinf.dk>.)
-- John Ellis' additions to the C++ support: From John:
-
-* I completely rewrote the documentation in the interface gc_c++.h
-(later renamed gc_cpp.h). I've tried to make it both clearer and more
-precise.
-
-* The definition of accessibility now ignores pointers from an
-finalizable object (an object with a clean-up function) to itself.
-This allows objects with virtual base classes to be finalizable by the
-collector. Compilers typically implement virtual base classes using
-pointers from an object to itself, which under the old definition of
-accessibility prevented objects with virtual base classes from ever
-being collected or finalized.
-
-* gc_cleanup now includes gc as a virtual base. This was enabled by
-the change in the definition of accessibility.
-* I added support for operator new[]. Since most (all?) compilers
-don't yet support operator new[], it is conditionalized on
--DOPERATOR_NEW_ARRAY. The code is untested, but its trivial and looks
-correct.
+[1.3]
+=====
-* The test program test_gc_c++ (later renamed test_cpp.cc)
-tries to test for the C++-specific functionality not tested by the
-other programs.
-- Added <unistd.h> include to misc.c. (Needed for ppcr.)
-- Added PowerMac port. (Thanks to Patrick Beard again.)
-- Fixed "srcdir"-related Makefile problems. Changed things so
- that all externally visible include files always appear in the
- include subdirectory of the source. Made gc.h directly
- includable from C++ code. (These were at Per
- Bothner's suggestion.)
-- Changed Intel code to also mark from ebp (Kevin Warne's
- suggestion).
-- Renamed C++ related files so they could live in a FAT
- file system. (Charles Fiterman's suggestion.)
-- Changed Windows NT Makefile to include C++ support in
- gc.lib. Added C++ test as Makefile target.
-
-Since version 4.3:
- - ASM_CLEAR_CODE was erroneously defined for HP
- PA machines, resulting in a compile error.
- - Fixed OS/2 Makefile to create a library. (Thanks to
- Mark Boulter (mboulter@vnet.ibm.com)).
- - Gc_cleanup objects didn't work if they were created on
- the stack. Fixed.
- - One copy of Gc_cpp.h in the distribution was out of
- synch, and failed to document some known compiler
- problems with explicit destructor invocation. Partially
- fixed. There are probably other compilers on which
- gc_cleanup is miscompiled.
- - Fixed Makefile to pass C compiler flags to C++ compiler.
- - Added Mac fixes.
- - Fixed os_dep.c to work around what appears to be
- a new and different VirtualQuery bug under newer
- versions of win32S.
- - GC_non_gc_bytes was not correctly maintained by
- GC_free. Fixed. Thanks to James Clark (jjc@jclark.com).
- - Added GC_set_max_heap_size.
- - Changed allocation code to ignore blacklisting if it is preventing
- use of a very large block of memory. This has the advantage
- that naive code allocating very large objects is much more
- likely to work. The downside is you might no
- longer find out that such code should really use
- GC_malloc_ignore_off_page.
- - Changed GC_printf under win32 to close and reopen the file
- between calls. FAT file systems otherwise make the log file
- useless for debugging.
- - Added GC_try_to_collect and GC_get_bytes_since_gc. These
- allow starting an abortable collection during idle times.
- This facility does not require special OS support. (Thanks to
- Michael Spertus of Geodesic Systems for suggesting this. It was
- actually an easy addition. Kumar Srikantan previously added a similar
- facility to a now ancient version of the collector. At the time
- this was much harder, and the result was less convincing.)
- - Added some support for the Borland development environment. (Thanks
- to John Ellis and Michael Spertus.)
- - Removed a misfeature from checksums.c that caused unexpected
- heap growth. (Thanks to Scott Schwartz.)
- - Changed finalize.c to call WARN if it encounters a finalization cycle.
- WARN is defined in gc_priv.h to write a message, usually to stdout.
- In many environments, this may be inappropriate.
- - Renamed NO_PARAMS in gc.h to GC_NO_PARAMS, thus adhering to my own
- naming convention.
- - Added GC_set_warn_proc to intercept warnings.
- - Fixed Amiga port. (Thanks to Michel Schinz (schinz@alphanet.ch).)
- - Fixed a bug in mark.c that could result in an access to unmapped
- memory from GC_mark_from_mark_stack on machines with unaligned
- pointers.
- - Fixed a win32 specific performance bug that could result in scanning of
- objects allocated with the system malloc.
- - Added REDIRECT_MALLOC.
-
-Since version 4.4:
- - Fixed many minor and one major README bugs. (Thanks to Franklin Chen
- (chen@adi.com) for pointing out many of them.)
- - Fixed ALPHA/OSF/1 dynamic library support. (Thanks to Jonathan Bachrach
- (jonathan@harlequin.com)).
- - Added incremental GC support (MPROTECT_VDB) for Linux (with some
- help from Bruno Haible).
- - Altered SPARC recognition tests in gc.h and config.h (mostly as
- suggested by Fergus Henderson).
- - Added basic incremental GC support for win32, as implemented by
- Windows NT and Windows 95. GC_enable_incremental is a noop
- under win32s, which doesn't implement enough of the VM interface.
- - Added -DLARGE_CONFIG.
- - Fixed GC_..._ignore_off_page to also function without
- -DALL_INTERIOR_POINTERS.
- - (Hopefully) fixed RS/6000 port. (Only the test was broken.)
- - Fixed a performance bug in the nonincremental collector running
- on machines supporting incremental collection with MPROTECT_VDB
- (e.g. SunOS 4, DEC AXP). This turned into a correctness bug under
- win32s with win32 incremental collection. (Not all memory protection
- was disabled.)
- - Fixed some ppcr related bit rot.
- - Caused dynamic libraries to be unregistered before reregistering.
- The old way turned out to be a performance bug on some machines.
- - GC_root_size was not properly maintained under MSWIN32.
- - Added -DNO_DEBUGGING and GC_dump.
- - Fixed a couple of bugs arising with SOLARIS_THREADS +
- REDIRECT_MALLOC.
- - Added NetBSD/M68K port. (Thanks to Peter Seebach
- <seebs@taniemarie.solon.com>.)
- - Fixed a serious realloc bug. For certain object sizes, the collector
- wouldn't scan the expanded part of the object. (Thanks to Clay Spence
- (cds@peanut.sarnoff.com) for noticing the problem, and helping me to
- track it down.)
-
-Since version 4.5:
- - Added Linux ELF support. (Thanks to Arrigo Triulzi <arrigo@ic.ac.uk>.)
- - GC_base crashed if it was called before any other GC_ routines.
- This could happen if a gc_cleanup object was allocated outside the heap
- before any heap allocation.
- - The heap expansion heuristic was not stable if all objects had finalization
- enabled. Fixed finalize.c to count memory in finalization queue and
- avoid explicit deallocation. Changed alloc.c to also consider this count.
- (This is still not recommended. It's expensive if nothing else.) Thanks
- to John Ellis for pointing this out.
- - GC_malloc_uncollectable(0) was broken. Thanks to Phong Vo for pointing
- this out.
- - The collector didn't compile under Linux 1.3.X. (Thanks to Fred Gilham for
- pointing this out.) The current workaround is ugly, but expected to be
- temporary.
- - Fixed a formatting problem for SPARC stack traces.
- - Fixed some '=='s in os_dep.c that should have been assignments.
- Fortunately these were in code that should never be executed anyway.
- (Thanks to Fergus Henderson.)
- - Fixed the heap block allocator to only drop blacklisted blocks in small
- chunks. Made BL_LIMIT self adjusting. (Both of these were in response
- to heap growth observed by Paul Graham.)
- - Fixed the Metrowerks/68K Mac code to also mark from a6. (Thanks
- to Patrick Beard.)
- - Significantly updated README.debugging.
- - Fixed some problems with longjmps out of signal handlers, especially under
- Solaris. Added a workaround for the fact that siglongjmp doesn't appear to
- do the right thing with -lthread under Solaris.
- - Added MSDOS/djgpp port. (Thanks to Mitch Harris (maharri@uiuc.edu).)
- - Added "make reserved_namespace" and "make user_namespace". The
- first renames ALL "GC_xxx" identifiers as "_GC_xxx". The second is the
- inverse transformation. Note that doing this is guaranteed to break all
- clients written for the other names.
- - descriptor field for kind NORMAL in GC_obj_kinds with ADD_BYTE_AT_END
- defined should be -ALIGNMENT not WORDS_TO_BYTES(-1). This is
- a serious bug on machines with pointer alignment of less than a word.
- - GC_ignore_self_finalize_mark_proc didn't handle pointers to very near the
- end of the object correctly. Caused failures of the C++ test on a DEC Alpha
- with g++.
- - gc_inl.h still had problems. Partially fixed. Added warnings at the
- beginning to hopefully specify the remaining dangers.
- - Added DATAEND definition to config.h.
- - Fixed some of the .h file organization. Fixed "make floppy".
-
-Since version 4.6:
- - Fixed some compilation problems with -DCHECKSUMS (thanks to Ian Searle)
- - Updated some Mac specific files to synchronize with Patrick Beard.
- - Fixed a serious bug for machines with non-word-aligned pointers.
- (Thanks to Patrick Beard for pointing out the problem. The collector
- should fail almost any conceivable test immediately on such machines.)
-
-Since version 4.7:
- - Changed a "comment" in a MacOS specific part of mach-dep.c that caused
- gcc to fail on other platforms.
-
-Since version 4.8
- - More README.debugging fixes.
- - Objects ready for finalization, but not finalized in the same GC
- cycle, could be prematurely collected. This occasionally happened
- in test_cpp.
- - Too little memory was obtained from the system for very large
- objects. That could cause a heap explosion if these objects were
- not contiguous (e.g. under PCR), and too much of them was blacklisted.
- - Due to an improper initialization, the collector was too hesitant to
- allocate blacklisted objects immediately after system startup.
- - Moved GC_arrays from the data into the bss segment by not explicitly
- initializing it to zero. This significantly
- reduces the size of executables, and probably avoids some disk accesses
- on program startup. It's conceivable that it might break a port that I
- didn't test.
- - Fixed EMX_MAKEFILE to reflect the gc_c++.h to gc_cpp.h renaming which
- occurred a while ago.
-
-Since 4.9:
- - Fixed a typo around a call to GC_collect_or_expand in alloc.c. It broke
- handling of out of memory. (Thanks to Patrick Beard for noticing.)
-
-Since 4.10:
- - Rationalized (hopefully) GC_try_to_collect in an incremental collection
- environment. It appeared to not handle a call while a collection was in
- progress, and was otherwise too conservative.
- - Merged GC_reclaim_or_delete_all into GC_reclaim_all to get rid of some
- code.
- - Added Patrick Beard's Mac fixes, with substantial completely untested
- modifications.
- - Fixed the MPROTECT_VDB code to deal with large pages and imprecise
- fault addresses (as on an UltraSPARC running Solaris 2.5). Note that this
- was not a problem in the default configuration, which uses PROC_VDB.
- - The DEC Alpha assembly code needed to restore $gp between calls.
- Thanks to Fergus Henderson for tracking this down and supplying a
- patch.
- - The write command for "de" was completely broken for large files.
- I used the easiest portable fix, which involved changing the semantics
- so that f.new is written instead of overwriting f. That's safer anyway.
- - Added README.solaris2 with a discussion of the possible problems of
- mixing the collector's sbrk allocation with malloc/realloc.
- - Changed the data segment starting address for SGI machines. The
- old code failed under IRIX6.
- - Required double word alignment for MIPS.
- - Various minor fixes to remove warnings.
- - Attempted to fix some Solaris threads problems reported by Zhiying Chen.
- In particular, the collector could try to fork a thread with the
- world stopped as part of GC_thr_init. It also failed to deal with
- the case in which the original thread terminated before the whole
- process did.
- - Added -DNO_EXECUTE_PERMISSION. This has a major performance impact
- on the incremental collector under Irix, and perhaps under other
- operating systems.
- - Added some code to support allocating the heap with mmap. This may
- be preferable under some circumstances.
- - Integrated dynamic library support for HP.
- (Thanks to Knut Tvedten <knuttv@ifi.uio.no>.)
- - Integrated James Clark's win32 threads support, and made a number
- of changes to it, many of which were suggested by Pontus Rydin.
- This is still not 100% solid.
- - Integrated Alistair Crooks' support for UTS4 running on an Amdahl
- 370-class machine.
- - Fixed a serious bug in explicitly typed allocation. Objects requiring
- large descriptors where handled in a way that usually resulted in
- a segmentation fault in the marker. (Thanks to Jeremy Fitzhardinge
- for helping to track this down.)
- - Added partial support for GNU win32 development. (Thanks to Fergus
- Henderson.)
- - Added optional support for Java-style finalization semantics. (Thanks
- to Patrick Bridges.) This is recommended only for Java implementations.
- - GC_malloc_uncollectable faulted instead of returning 0 when out of
- memory. (Thanks to dan@math.uiuc.edu for noticing.)
- - Calls to GC_base before the collector was initialized failed on a
- DEC Alpha. (Thanks to Matthew Flatt.)
- - Added base pointer checking to GC_REGISTER_FINALIZER in debugging
- mode, at the suggestion of Jeremy Fitzhardinge.
- - GC_debug_realloc failed for uncollectable objects. (Thanks to
- Jeremy Fitzhardinge.)
- - Explicitly typed allocation could crash if it ran out of memory.
- (Thanks to Jeremy Fitzhardinge.)
- - Added minimal support for a DEC Alpha running Linux.
- - Fixed a problem with allocation of objects whose size overflowed
- ptrdiff_t. (This now fails unconditionally, as it should.)
- - Added the beginning of Irix pthread support.
- - Integrated Xiaokun Zhu's fixes for djgpp 2.01.
- - Added SGI-style STL allocator support (gc_alloc.h).
- - Fixed a serious bug in README.solaris2. Multithreaded programs must include
- gc.h with SOLARIS_THREADS defined.
- - Changed GC_free so it actually deallocates uncollectable objects.
- (Thanks to Peter Chubb for pointing out the problem.)
- - Added Linux ELF support for dynamic libararies. (Thanks again to
- Patrick Bridges.)
- - Changed the Borland cc configuration so that the assembler is not
- required.
- - Fixed a bug in the C++ test that caused it to fail in 64-bit
- environments.
-
-Since 4.11:
- - Fixed ElfW definition in dyn_load.c. (Thanks to Fergus Henderson.)
- This prevented the dynamic library support from compiling on some
- older ELF Linux systems.
- - Fixed UTS4 port (which I apparently mangled during the integration)
- (Thanks to again to Alistair Crooks.)
- - "Make C++" failed on Suns with SC4.0, due to a problem with "bool".
- Fixed in gc_priv.h.
- - Added more pieces for GNU win32. (Thanks to Timothy N. Newsham.)
- The current state of things should suffice for at least some
- applications.
- - Changed the out of memory retry count handling as suggested by
- Kenjiro Taura. (This matters only if GC_max_retries > 0, which
- is no longer the default.)
- - If a /proc read failed repeatedly, GC_written_pages was not updated
- correctly. (Thanks to Peter Chubb for diagnosing this.)
- - Under unlikely circumstances, the allocator could infinite loop in
- an out of memory situation. (Thanks again to Kenjiro Taura for
- identifying the problem and supplying a fix.)
- - Fixed a syntactic error in the DJGPP code. (Thanks to Fergus
- Henderson for finding this by inspection.) Also fixed a test program
- problem with DJGPP (Thanks to Peter Monks.)
- - Atomic uncollectable objects were not treated correctly by the
- incremental collector. This resulted in weird log statistics and
- occasional performance problems. (Thanks to Peter Chubb for pointing
- this out.)
- - Fixed some problems resulting from compilers that dont define
- __STDC__. In this case void * and char * were used inconsistently
- in some cases. (Void * should not have been used at all. If
- you have an ANSI superset compiler that does not define __STDC__,
- please compile with -D__STDC__=0. Thanks to Manuel Serrano and others
- for pointing out the problem.)
- - Fixed a compilation problem on Irix with -n32 and -DIRIX_THREADS.
- Also fixed some other IRIX_THREADS problems which may or may not have
- had observable symptoms.
- - Fixed an HP PA compilation problem in dyn_load.c. (Thanks to
- Philippe Queinnec.)
- - SEGV fault handlers sometimes did not get reset correctly. (Thanks
- to David Pickens.)
- - Added a fix for SOLARIS_THREADS on Intel. (Thanks again to David
- Pickens.) This probably needs more work to become functional.
- - Fixed struct sigcontext_struct in os_dep.c for compilation under
- Linux 2.1.X. (Thanks to Fergus Henderson.)
- - Changed the DJGPP STACKBOTTOM and DATASTART values to those suggested
- by Kristian Kristensen. These may still not be right, but it is
- it is likely to work more often than what was there before. They may
- even be exactly right.
- - Added a #include <string.h> to test_cpp.cc. This appears to help
- with HP/UX and gcc. (Thanks to assar@sics.se.)
- - Version 4.11 failed to run in incremental mode on recent 64-bit Irix
- kernels. This was a problem related to page unaligned heap segments.
- Changed the code to page align heap sections on all platforms.
- (I had mistakenly identified this as a kernel problem earlier.
- It was not.)
- - Version 4.11 did not make allocated storage executable, except on
- one or two platforms, due to a bug in a #if test. (Thanks to Dave
- Grove for pointing this out.)
- - Added sparc_sunos4_mach_dep.s to support Sun's compilers under SunOS4.
- - Added GC_exclude_static_roots.
- - Fixed the object size mapping algorithm. This shouldn't matter,
- but the old code was ugly.
- - Heap checking code could die if one of the allocated objects was
- larger than its base address. (Unsigned underflow problem. Thanks
- to Clay Spence for isolating the problem.)
- - Added RS6000 (AIX) dynamic library support and fixed STACK_BOTTOM.
- (Thanks to Fred Stearns.)
- - Added Fergus Henderson's patches for improved robustness with large
- heaps and lots of blacklisting.
- - Added Peter Chubb's changes to support Solaris Pthreads, to support
- MMAP allocation in Solaris, to allow Solaris to find dynamic libraries
- through /proc, to add malloc_typed_ignore_off_page, and a few other
- minor features and bug fixes.
- - The Solaris 2 port should not use sbrk. I received confirmation from
- Sun that the use of sbrk and malloc in the same program is not
- supported. The collector now defines USE_MMAP by default on Solaris.
- - Replaced the djgpp makefile with Gary Leavens' version.
- - Fixed MSWIN32 detection test.
- - Added Fergus Henderson's patches to allow putting the collector into
- a DLL under GNU win32.
- - Added Ivan V. Demakov's port to Watcom C on X86.
- - Added Ian Piumarta's Linux/PowerPC port.
- - On Brian Burton's suggestion added PointerFreeGC to the placement
- options in gc_cpp.h. This is of course unsafe, and may be controversial.
- On the other hand, it seems to be needed often enough that it's worth
- adding as a standard facility.
-
-Since 4.12:
- - Fixed a crucial bug in the Watcom port. There was a redundant decl
- of GC_push_one in gc_priv.h.
- - Added FINALIZE_ON_DEMAND.
- - Fixed some pre-ANSI cc problems in test.c.
- - Removed getpagesize() use for Solaris. It seems to be missing in one
- or two versions.
- - Fixed bool handling for SPARCCompiler version 4.2.
- - Fixed some files in include that had gotten unlinked from the main
- copy.
- - Some RS/6000 fixes (missing casts). Thanks to Toralf Foerster.
- - Fixed several problems in GC_debug_realloc, affecting mostly the
- FIND_LEAK case.
- - GC_exclude_static_roots contained a buggy unsigned comparison to
- terminate a loop. (Thanks to Wilson Ho.)
- - CORD_str failed if the substring occurred at the last possible position.
- (Only affects cord users.)
- - Fixed Linux code to deal with RedHat 5.0 and integrated Peter Bigot's
- os_dep.c code for dealing with various Linux versions.
- - Added workaround for Irix pthreads sigaction bug and possible signal
- misdirection problems.
-Since alpha1:
- - Changed RS6000 STACKBOTTOM.
- - Integrated Patrick Beard's Mac changes.
- - Alpha1 didn't compile on Irix m.n, m < 6.
- - Replaced Makefile.dj with a new one from Gary Leavens.
- - Added Andrew Stitcher's changes to support SCO OpenServer.
- - Added PRINT_BLACK_LIST, to allow debugging of high densities of false
- pointers.
- - Added code to debug allocator to keep track of return address
- in GC_malloc caller, thus giving a bit more context.
- - Changed default behavior of large block allocator to more
- aggressively avoid fragmentation. This is likely to slow down the
- collector when it succeeds at reducing space cost.
- - Integrated Fergus Henderson's CYGWIN32 changes. They are untested,
- but needed for newer versions.
- - USE_MMAP had some serious bugs. This caused the collector to fail
- consistently on Solaris with -DSMALL_CONFIG.
- - Added Linux threads support, thanks largely to Fergus Henderson.
-Since alpha2:
- - Fixed more Linux threads problems.
- - Changed default GC_free_space_divisor to 3 with new large block allocation.
- (Thanks to Matthew Flatt for some measurements that suggest the old
- value sometimes favors space too much over time.)
- - More CYGWIN32 fixes.
- - Integrated Tyson-Dowd's Linux-M68K port.
- - Minor HP PA and DEC UNIX fixes from Fergus Henderson.
- - Integrated Christoffe Raffali's Linux-SPARC changes.
- - Allowed for one more GC fixup iteration after a full GC in incremental
- mode. Some quick measurements suggested that this significantly
- reduces pause times even with smaller GC_RATE values.
- - Moved some more GC data structures into GC_arrays. This decreases
- pause times and GC overhead, but makes debugging slightly less convenient.
- - Fixed namespace pollution problem ("excl_table").
- - Made GC_incremental a constant for -DSMALL_CONFIG, hopefully shrinking
- that slightly.
- - Added some win32 threads fixes.
- - Integrated Ivan Demakov and David Stes' Watcom fixes.
- - Various other minor fixes contributed by many people.
- - Renamed config.h to gcconfig.h, since config.h tends to be used for
- many other things.
- - Integrated Matthew Flatt's support for 68K MacOS "far globals".
- - Fixed up some of the dynamic library Makefile targets for consistency
- across platforms.
- - Fixed a USE_MMAP typo that caused out-of-memory handling to fail
- on Solaris.
- - Added code to test.c to test thread creation a bit more.
- - Integrated GC_win32_free_heap, as suggested by Ivan Demakov.
- - Fixed Solaris 2.7 stack base finding problem. (This may actually
- have been done in an earlier alpha release.)
-Since alpha3:
- - Fixed MSWIN32 recognition test, which interfered with cygwin.
- - Removed unnecessary gc_watcom.asm from distribution. Removed
- some obsolete README.win32 text.
- - Added Alpha Linux incremental GC support. (Thanks to Philipp Tomsich
- for code for retrieving the fault address in a signal handler.)
- Changed Linux signal handler context argument to be a pointer.
- - Took care of some new warnings generated by the 7.3 SGI compiler.
- - Integrated Phillip Musumeci's FreeBSD/ELF fixes.
- - -DIRIX_THREADS was broken with the -o32 ABI (typo in gc_priv.h>
-
-Since 4.13:
- - Fixed GC_print_source_ptr to not use a prototype.
- - generalized CYGWIN test.
- - gc::new did the wrong thing with PointerFreeGC placement.
- (Thanks to Rauli Ruohonen.)
- - In the ALL_INTERIOR_POINTERS (default) case, some callee-save register
- values could fail to be scanned if the register was saved and
- reused in a GC frame. This showed up in verbose mode with gctest
- compiled with an unreleased SGI compiler. I vaguely recall an old
- bug report that may have been related. The bug was probably quite old.
- (The problem was that the stack scanning could be deferred until
- after the relevant frame was overwritten, and the new save location
- might be outside the scanned area. Fixed by more eager stack scanning.)
- - PRINT_BLACK_LIST had some problems. A few source addresses were garbage.
- - Replaced Makefile.dj and added -I flags to cord make targets.
- (Thanks to Gary Leavens.)
- - GC_try_to_collect was broken with the nonincremental collector.
- - gc_cleanup destructors could pass the wrong address to
- GC_register_finalizer_ignore_self in the presence of multiple
- inheritance. (Thanks to Darrell Schiebel.)
- - Changed PowerPC Linux stack finding code.
-
-Since 4.14alpha1
- - -DSMALL_CONFIG did not work reliably with large (> 4K) pages.
- Recycling the mark stack during expansion could result in a size
- zero heap segment, which confused things. (This was probably also an
- issue with the normal config and huge pages.)
- - Did more work to make sure that callee-save registers were scanned
- completely, even with the setjmp-based code. Added USE_GENERIC_PUSH_REGS
- macro to facilitate testing on machines I have access to.
- - Added code to explicitly push register contents for win32 threads.
- This seems to be necessary. (Thanks to Pierre de Rop.)
-
-Since 4.14alpha2
- - changed STACKBOTTOM for DJGPP (Thanks to Salvador Eduardo Tropea).
-
-Since 4.14
- - Reworked large block allocator. Now uses multiple doubly linked free
- lists to approximate best fit.
- - Changed heap expansion heuristic. Entirely free blocks are no longer
- counted towards the heap size. This seems to have a major impact on
- heap size stability; the old version could expand the heap way too
- much in the presence of large block fragmentation.
- - added -DGC_ASSERTIONS and some simple assertions inside the collector.
- This is mainlyt for collector debugging.
- - added -DUSE_MUNMAP to allow the heap to shrink. Suupported on only
- a few UNIX-like platforms for now.
- - added GC_dump_regions() for debugging of fragmentation issues.
- - Changed PowerPC pointer alignment under Linux to 4. (This needs
- checking by someone who has one. The suggestions came to me via a
- rather circuitous path.)
- - Changed the Linux/Alpha port to walk the data segment backwards until
- it encounters a SIGSEGV. The old way to find the start of the data
- segment broke with a recent release.
- - cordxtra.c needed to call GC_REGISTER_FINALIZER instead of
- GC_register_finalizer, so that it would continue to work with GC_DEBUG.
- - allochblk sometimes cleared the wrong block for debugging purposes
- when it dropped blacklisted blocks. This could result in spurious
- error reports with GC_DEBUG.
- - added MACOS X Server support. (Thanks to Andrew Stone.)
- - Changed the Solaris threads code to ignore stack limits > 8 MB with
- a warning. Empirically, it is not safe to access arbitrary pages
- in such large stacks. And the dirty bit implementation does not
- guarantee that none of them will be accessed.
- - Integrated Martin Tauchmann's Amiga changes.
- - Integrated James Dominy's OpenBSD/SPARC port.
-
-Since 5.0alpha1
- - Fixed bugs introduced in alpha1 (OpenBSD & large block initialization).
- - Added -DKEEP_BACK_PTRS and backptr.h interface. (The implementation
- idea came from Al Demers.)
-
-Since 5.0alpha2
- - Added some highly incomplete code to support a copied young generation.
- Comments on nursery.h are appreciated.
- - Changed -DFIND_LEAK, -DJAVA_FINALIZATION, and -DFINALIZE_ON_DEMAND,
- so the same effect could be obtained with a runtime switch. This is
- a step towards standardizing on a single dynamic GC library.
- - Significantly changed the way leak detection is handled, as a consequence
- of the above.
-
-Since 5.0 alpha3
- - Added protection fault handling patch for Linux/M68K from Fergus
- Henderson and Roman Hodek.
- - Removed the tests for SGI_SOURCE in new_gc_alloc.h. This was causing that
- interface to fail on nonSGI platforms.
- - Changed the Linux stack finding code to use /proc, after changing it
- to use HEURISTIC1. (Thanks to David Mossberger for pointing out the
- /proc hook.)
- - Added HP/UX incremental GC support and HP/UX 11 thread support.
- Thread support is currently still flakey.
- - Added basic Linux/IA64 support.
- - Integrated Anthony Green's PicoJava support.
- - Integrated Scott Ananian's StrongARM/NetBSD support.
- - Fixed some fairly serious performance bugs in the incremental
- collector. These have probably been there essentially forever.
- (Mark bits were sometimes set before scanning dirty pages.
- The reclaim phase unnecessarily dirtied full small object pages.)
- - Changed the reclaim phase to ignore nearly full pages to avoid
- touching them.
- - Limited GC_black_list_spacing to roughly the heap growth increment.
- - Changed full collection triggering heuristic to decrease full GC
- frequency by default, but to explicitly trigger full GCs during
- heap growth. This doesn't always improve things, but on average it's
- probably a win.
- - GC_debug_free(0, ...) failed. Thanks to Fergus Henderson for the
- bug report and fix.
-
-Since 5.0 alpha4
- - GC_malloc_explicitly_typed and friends sometimes failed to
- initialize first word.
- - Added allocation routines and support in the marker for mark descriptors
- in a type structure referenced by the first word of an object. This was
- introduced to support gcj, but hopefully in a way that makes it
- generically useful.
- - Added GC_requested_heapsize, and inhibited collections in nonincremental
- mode if the actual used heap size is less than what was explicitly
- requested.
- - The Solaris pthreads version of GC_pthread_create didn't handle a NULL
- attribute pointer. Solaris thread support used the wrong default thread
- stack size. (Thanks to Melissa O'Neill for the patch.)
- - Changed PUSH_CONTENTS macro to no longer modify first parameter.
- This usually doesn't matter, but it was certainly an accident waiting
- to happen ...
- - Added GC_register_finalizer_no_order and friends to gc.h. They're
- needed by Java implementations.
- - Integrated a fix for a win32 deadlock resulting from clock() calling
- malloc. (Thanks to Chris Dodd.)
- - Integrated Hiroshi Kawashima's port to Linux/MIPS. This was designed
- for a handheld platform, and may or may not be sufficient for other
- machines.
- - Fixed a va_arg problem with the %c specifier in cordprnt.c. It appears
- that this was always broken, but recent versions of gcc are the first to
- report the (statically detectable) bug.
- - Added an attempt at a more general solution to dlopen races/deadlocks.
- GC_dlopen now temporarily disables collection. Still not ideal, but ...
- - Added -DUSE_I686_PREFETCH, -DUSE_3DNOW_PREFETCH, and support for IA64
- prefetch instructions. May improve performance measurably, but I'm not
- sure the code will run correctly on processors that don't support the
- instruction. Won't build except with very recent gcc.
- - Added caching for header lookups in the marker. This seems to result
- in a barely measurable performance gain. Added support for interleaved
- lookups of two pointers, but unconfigured that since the performance
- gain is currently near zero, and it adds to code size.
- - Changed Linux DATA_START definition to check both data_start and
- __data_start, since nothing else seems to be portable.
- - Added -DUSE_LD_WRAP to optionally take advantage of the GNU ld function
- wrapping mechanism. Probably currently useful only on Linux.
- - Moved some variables for the scratch allocator into GC_arrays, on
- Martin Hirzel's suggestion.
- - Fixed a win32 threads bug that caused the collector to not look for
- interior pointers from one of the thread stacks without
- ALL_INTERIOR_POINTERS. (Thanks to Jeff Sturm.)
- - Added Mingw32 support. (Thanks again to Jeff Sturm for the patch.)
- - Changed the alpha port to use the generic register scanning code instead
- of alpha_mach_dep.s. Alpha_mach_dep.s doesn't look for pointers in fp
- registers, but gcc sometimes spills pointers there. (Thanks to Manuel
- Serrano for helping me debug this by email.) Changed the IA64 code to
- do something similar for similar reasons.
-
-[5.0alpha5 doesn't really exist, but it may have escaped.]
-
-Since 5.0alpha6:
- - -DREDIRECT_MALLOC was broken in alpha6. Fixed.
- - Cleaned up gc_ccp.h slightly, thus also causing the HP C++ compiler to
- accept it.
- - Removed accidental reference to dbg_mlc.c, which caused dbg_mlc.o to be
- linked into every executable.
- - Added PREFETCH to bitmap marker. Changed it to use the header cache.
- - GC_push_marked sometimes pushed one object too many, resulting in a
- segmentation fault in GC_mark_from_mark_stack. This was probably an old
- bug. It finally showed up in gctest on win32.
- - Gc_priv.h erroneously #defined GC_incremental to be TRUE instead of FALSE
- when SMALL_CONFIG was defined. This was no doubt a major performance bug for
- the default win32 configuration.
- - Removed -DSMALL_CONFIG from NT_MAKEFILE. It seemed like an anchronism now
- that the average PC has 64MB or so.
- - Integrated Bryce McKinley's patches for linux threads and dynamic loading
- from the libgcj tree. Turned on dynamic loading support for Linux/PPC.
- - Changed the stack finding code to use environ on HP/UX. (Thanks
- to Gustavo Rodriguez-Rivera for the suggestion.) This should probably
- be done on other platforms, too. Since I can't test those, that'll
- wait until after 5.0.
-
-Since 5.0alpha7:
- - Fixed threadlibs.c for linux threads. -DUSE_LD_WRAP was broken and
- -ldl was omitted. Fixed Linux stack finding code to handle
- -DUSE_LD_WRAP correctly.
- - Added MSWIN32 exception handler around marker, so that the collector
- can recover from root segments that are unmapped during the collection.
- This caused occasional failures under Windows 98, and may also be
- an issue under Windows NT/2000.
-
-Since 5.0
- - Fixed a gc.h header bug which showed up under Irix. (Thanks to
- Dan Sullivan.)
- - Fixed a typo in GC_double_descr in typd_mlc.c.
- This probably could result in objects described by array descriptors not
- getting traced correctly. (Thanks to Ben Hutchings for pointing this out.)
- - The block nearly full tests in reclaim.c were not correct for 64 bit
- environments. This could result in unnecessary heap growth under unlikely
- conditions.
-
-Since 5.1
- - dyn_load.c declared GC_scratch_last_end_ptr as an extern even if it
- was defined as a macro. This prevented the collector from building on
- Irix.
- - We quietly assumed that indirect mark descriptors were never 0.
- Our own typed allocation interface violated that. This could result
- in segmentation faults in the marker with typed allocation.
- - Fixed a _DUSE_MUNMAP bug in the heap block allocation code.
- (Thanks to Ben Hutchings for the patch.)
- - Taught the collector about VC++ handling array operator new.
- (Thanks again to Ben Hutchings for the patch.)
- - The two copies of gc_hdrs.h had diverged. Made one a link to the other
- again.
-
-Since 5.2 (A few 5.2 patches are not in 6.0alpha1)
- - Fixed _end declaration for OSF1.
- - There were lots of spurious leak reports in leak detection mode, caused
- by the fact that some pages were not being swept, and hence unmarked
- objects weren't making it onto free lists. (This bug dated back to 5.0.)
- - Fixed a typo in the liblinuxgc.so Makefile rule.
- - Added the GetExitCodeThread to Win32 GC_stop_world to (mostly) work
- around a Windows 95 GetOpenFileName problem. (Thanks to Jacob Navia.)
-
-Since 5.3
- - Fixed a typo that prevented compilation with -DUSE_3DNOW_PREFETCH.
- (Thanks to Shawn Wagner for actually testing this.)
- - Fixed GC_is_thread_stack in solaris_threads.c. It forgot to return a value
- in the common case. I wonder why nobody noticed?
- - Fixed another silly syntax problem in GC_double_descr. (Thanks to
- Fergus Henderson for finding it.)
- - Fixed a GC_gcj_malloc bug: It tended to release the allocator lock twice.
-
-Since 5.4 (A few 5.3 patches are not in 6.0alpha2)
- - Added HP/PA prefetch support.
- - Added -DDBG_HDRS_ALL and -DSHORT_DBG_HDRS to reduce the cost and improve
- the reliability of generating pointer backtrace information, e.g. in
- the Bigloo environment.
- - Added parallel marking support (-DPARALLEL_MARK). This currently
- works only under IA32 and IA64 Linux, but it shouldn't be hard to adapt
- to other platforms. This is intended to be a lighter-weight (less
- new code, probably not as scalable) solution than the work by Toshio Endo
- et al, at the University of Tokyo. A number of their ideas were
- reused, though the code wasn't, and the underlying data structure
- is significantly different. In particular, we keep the global mark
- stack as a single shared data structure, but most of the work is done
- on smaller thread-local mark stacks.
- - Changed GC_malloc_many to be cheaper, and to require less mutual exclusion
- with -DPARALLEL_MARK.
- - Added full support for thread local allocation under Linux
- (-DTHREAD_LOCAL_ALLOC). This is a thin veneer on GC_malloc_many, and
- should be easily portable to other platforms, especially those that
- support pthreads.
- - CLEAR_DOUBLE was not always getting invoked when it should have been.
- - GC_gcj_malloc and friends used different out of memory handling than
- everything else, probably because I forgot about one when I implemented
- the other. They now both call GC_oom_fn(), not GC_oom_action().
- - Integrated Jakub Jelinek's fixes for Linux/SPARC.
- - Moved GC_objfreelist, GC_aobjfreelist, and GC_words_allocd out of
- GC_arrays, and separately registered the first two as excluded roots.
- This makes code compiled with gc_inl.h less dependent on the
- collector version. (It would be nice to remove the inclusion of
- gc_priv.h by gc_inl.h completely, but we're not there yet. The
- locking definitions in gc_priv.h are still referenced.)
- This change was later coniditoned on SEPARATE_GLOBALS, which
- is not defined by default, since it involves a performance hit.
- - Register GC_obj_kinds separately as an excluded root region. The
- attempt to register it with GC_arrays was usually failing. (This wasn't
- serious, but seemed to generate some confusion.)
- - Moved backptr.h to gc_backptr.h.
-
-Since 6.0alpha1
- - Added USE_MARK_BYTES to reduce the need for compare-and-swap on platforms
- for which that's expensive.
- - Fixed a locking bug ib GC_gcj_malloc and some locking assertion problems.
- - Added a missing volatile to OR_WORD and renamed the parameter to
- GC_compare_and_swap so it's not a C++ reserved word. (Thanks to
- Toshio Endo for pointing out both of those.)
- - Changed Linux dynamic library registration code to look at /proc/self/maps
- instead of the rld data structures when REDIRECT_MALLOC is defined.
- Otherwise some of the rld data data structures may be prematurely garbage
- collected. (Thanks to Eric Benson for helping to track this down.)
- - Fixed USE_LD_WRAP a bit more, so it should now work without threads.
- - Renamed XXX_THREADS macros to GC_XXX_THREADS for namespace correctness.
- Tomporarily added some backward compatibility definitions. Renamed
- USE_LD_WRAP to GC_USE_LD_WRAP.
- - Many MACOSX POWERPC changes, some additions to the gctest output, and
- a few minor generic bug fixes. (Thanks to Dietmar Planitzer.)
-
-Since 6.0 alpha2
- - Fixed the /proc/self/maps code to not seek, since that apparently is not
- reliable across all interesting kernels.
- - Fixed some compilation problems in the absence of PARALLEL_MARK
- (introduced in alpha2).
- - Fixed an algorithmic problem with PARALLEL_MARK. If work needs to
- be given back to the main mark "stack", the BOTTOM entries of the local
- stack should be given away, not the top ones. This has substantial
- performance impact, especially for > 2 processors, from what I can tell.
- - Extracted gc_lock.h from gc_priv.h. This should eventually make it a
- bit easier to avoid including gc_priv.h in clients.
- - Moved all include files to include/ and removed duplicate links to the
- same file. The old scheme was a bad idea because it was too easy to get the
- copies out of sync, and many systems don't support hard links.
- Unfortunately, it's likely that I broke some of the non-Unix Makefiles in
- the process, although I tried to update them appropriately.
- - Removed the partial support for a copied nursery. It's not clear that
- this would be a tremendous win, since we don't consistently lose to
- generational copying collectors. And it would significantly complicate
- many things. May be reintroduced if/when it really turns out to win.
- - Removed references to IRIX_JDK_THREADS, since I believe there never
- were and never will be any clients.
- - Added some code to linux_threads.c to possibly support HPUX threads
- using the Linux code. Unfortunately, it doesn't work yet, and is
- currently disabled.
- - Added support under Linux/X86 for saving the call chain, both in (debug)
- objects for client debugging, and in GC_arrays._last_stack for GC
- debugging. This was previously supported only under Solaris. It is
- not enabled by default under X86, since it requires that code be compiled
- to explicitly dave frame pointers on the call stack. (With gcc this
- currently happens by default, but is often turned off explicitly.)
- To turn it on, define SAVE_CALL_CHAIN.
-
-Since 6.0 alpha3
- - Moved up the detection of mostly full blocks to the initiatiation of the
- sweep phase. This eliminates some lock conention in the PARALLEL_MARK case,
- as multiple threads try to look at mostly full blocks concurrently.
- - Restored the code in GC_malloc_many that grabs a prefix of the global
- free list. This avoids the case in which every GC_malloc_many call
- tries and fails to allocate a new heap block, and the returns a single
- object from the global free list.
- - Some minor fixes in new_hblk.c. (Attempted to build free lists in order
- of increasing addresses instead of decreasing addresses for cache performance
- reasons. But this seems to be only a very minor gain with -DEAGER_SWEEP,
- and a loss in other cases. So the change was backed out.)
- - Fixed some of the documentation. (Thanks in large part to Fergus
- Henderson.)
- - Fixed the Linux USE_PROC_FOR_LIBRARIES code to deal with apps that perform
- large numbers of mmaps. (Thanks to Eric Benson.) Also fixed that code to
- deal with short reads.
- - Added GC_get_total_bytes().
- - Fixed leak detection mode to avoid spurious messages under linuxthreads.
- (This should also now be easy for the other supported threads packages.
- But the code is tricky enough that I'm hesitant to do it without being able
- to test. Everything allocated in the GC thread support itself should be
- explicitly deallocated.)
- - Made it possible (with luck) to redirect malloc to GC_local_malloc.
-
-Since 6.0 alpha4
- - Changed the definition of GC_pause in linux_threads.c to use a volatile
- asm. Some versions of gcc apparently optimize away writes to local volatile
- variables. This caused poor locking behaviour starting at about
- 4 processors.
- - Added GC_start_blocking(), GC_end_blocking() calls and wrapper for sleep
- to linux_threads.c.
- The first two calls could be used to generally avoid sending GC signals to
- blocked threads, avoiding both premature wakeups and unnecessary overhead.
- - Fixed a serious bug in thread-local allocation. At thread termination,
- GC_free could get called on small integers. Changed the code for thread
- termination to more efficiently return left-over free-lists.
- - Integrated Kjetil Matheussen's BeOS support.
- - Rearranged the directory structure to create the doc and tests
- subdirectories.
- - Sort of integrated Eric Benson's patch for OSF1. This provided basic
- OSF1 thread support by suitably extending hpux_irix_threads.c. Based
- on earlier email conversations with David Butenhof, I suspect that it
- will be more reliable in the long run to base this on linux_threads.c
- instead. Thus I attempted to patch up linux_threads.c based on Eric's code.
- The result is almost certainly broken, but hopefully close enough that
- someone with access to a machine can pick it up.
- - Integrated lots of minor changes from the NetBSD distribution. (These
- were supplied by David Brownlee. I'm not sure about the original
- authors.)
- - Hacked a bit more on the HP/UX thread-support in linux_threads.c. It
- now appears to work in the absence of incremental collection. Renamed
- hpux_irix_threads.c back to irix_threads.c, and removed the attempt to
- support HPUX there.
- - Changed gc.h to define _REENTRANT in cases in which it should already
- have been defined. It is still safer to also define it on the command
- line.
-
-Since 6.0alpha5:
- - Changed the definition of DATASTART on ALPHA and IA64, where data_start
- and __data_start are not defined by earlier versions of glibc. This might
- need to be fixed on other platforms as well.
- - Changed the way the stack base and backing store base are found on IA64.
- This should now remain reliable on future kernels. But since it relies
- on /proc, it will no longer work in the simulated NUE environment.
- - Made the call to random() in dbg_mlc.c with -DKEEP_BACK_PTRS dependent
- on the OS. On non-Unix systems, rand() should be used instead. Handled
- small RAND_MAX. (Thanks to Peter Ross for pointing this out.)
- - Fixed the cord make rules to create the cord subdirectory, if necessary.
- (Thanks to Doug Moen.)
- - Changed fo_object_size calculation in finalize.c. Turned finalization
- of nonheap object into a no-op. Removed anachronism from GC_size()
- implementation.
- - Changed GC_push_dirty call in solaris_threads.c to GC_push_selected.
- It was missed in a previous renaming. (Thanks to Vladimir Tsichevski
- for pointing this out.)
- - Arranged to not not mask SIGABRT in linux_threads.c. (Thanks to Bryce
- McKinlay.)
- - Added GC_no_dls hook for applications that want to register their own
- roots.
- - Integrated Kjetil Matheussen's Amiga changes.
- - Added FREEBSD_STACKBOTTOM. Changed the X86/FreeBSD port to use it.
- (Thanks to Matthew Flatt.)
- - Added pthread_detach interception for platforms supported by linux_threads.c
- and irix_threads.c. Should also be added for Solaris?
- - Changed the USE_MMAP code to check for the case in which we got the
- high end of the address space, i.e. mem_ptr + mem_sz == 0. It appears
- that this can happen under Solaris 7. It seems to be allowed by what
- I would claim is an oversight in the mmap specification. (Thanks to Toshio
- Endo for pointing out the problem.)
- - Cleanup of linux_threads.c. Some code was originally cloned from
- irix_threads.c and now unnecessary. Some comments were obviously wrong.
- - (Mostly) fixed a longstanding problem with setting of dirty bits from
- a signal handler. In the presence of threads, dirty bits could get lost,
- since the etting of a bit in the bit vector was not atomic with respect
- to other updates. The fix is 100% correct only for platforms for which
- GC_test_and_set is defined. The goal is to make that all platforms with
- thread support. Matters only if incremental GC and threads are both
- enabled.
- - made GC_all_interior_pointers (a.k.a. ALL_INTERIOR_POINTERS) an
- initialization time, instead of build-time option. This is a
- nontrivial, high risk change. It should slow down the code measurably
- only if MERGE_SIZES is not defined, which is a very nonstandard
- configuration.
- - Added doc/README.environment, and implemented what it describes. This
- allows a number of additional configuration options to be set through
- the environment. It documents a few previously undocumented options.
- - Integrated Eric Benson's leak testing improvements.
- - Removed the option to throw away the beginning of each page (DISCARD_WORDS).
- This became less and less useful as processors enforce stricter alignment.
- And it hadn't been tested in ages, and was thus probably broken anyway.
-
-Since 6.0alpha6:
- - Added GC_finalizer_notifier. Fixed GC_finalize_on_demand. (The variable
- actually wasn't being tested at the right points. The build-time flag
- was.)
- - Added Tom Tromey's S390 Linux patch.
- - Added code to push GC_finalize_now in GC_push_finalizer_structures.
- (Thanks to Matthew Flatt.)
- - Added GC_push_gc_structures() to push all GC internal roots.
- - Integrated some FreeBSD changes from Matthew Flatt.
- - It looks like USRSTACK is not always correctly defined under Solaris.
- Hacked gcconfig.h to attempt to work around the problem. The result
- is not well tested. (Thanks again to Matthew Flatt for pointing this
- out. The gross hack is mine. - HB)
- - Added Ji-Yong Chung's win32 threads and C++ fixes.
- - Arranged for hpux_test_and_clear.s to no longer be needed or built.
- It was causing build problems with gas, and it's not clear this is
- better than the pthreads alternative on this platform.
- - Some MINGW32 fixes from Hubert Garavel.
- - Added Initial Hitachi SH4 port from Kaz Kojima.
- - Ported thread-local allocation and parallel mark code to HP/UX on PA_RISC.
- - Made include/gc_mark.h more public and separated out the really private
- pieces. This is probably still not quite sufficient for clients that
- want to supply their own kind of type information. But it's a start.
- This involved lots of identifier renaming to make it namespace clean.
- - Added GC_dont_precollect for clients that need complete control over
- the root set.
- - GC_is_visible didn't do the right thing with gcj objects. (Not that
- many people are likely to care, but ...)
- - Don't redefine read with GC_USE_LD_WRAP.
- - Initial port to LINUX/HP_PA. Incremental collection and threads are not
- yet supported. (Incremental collection should work if you have the
- right kernel. Threads may work with a sufficiently patched pthread
- library.)
- - Changed gcconfig.h to recognize __i386__ as an alternative to i386 in
- many places. (Thanks to Benjamin Lerman.)
- - Made win32_threads.c more tolerant of detaching a thread that it didn't
- know about. (Thanks to Paul Nash.)
- - Added Makefile.am and configure.in from gcc to the distribution, with
- minimal changes. For the moment, those are just placeholders. In the
- future, we're planning to switch to a GNU-style build environment for
- Un*x-like systems, though the old Makefile will remain as a backup.
- - Turned off STUBBORN_ALLOC by default, and added it back as a Makefile
- option.
- - Redistributed some functions between malloc.c and mallocx.c, so that
- simple statically linked apps no longer pull in mallocx.o.
- - Changed large object allocation to clear the first and last few words
- of each block before releassing the lock. Otherwise the marker could see
- objects with nonsensical type descriptors.
- - Fixed a couple of subtle problems that could result in not recognizing
- interior pointers from the stack. (I believe these were introduced
- in 6.0alpha6.)
- - GC_debug_free_inner called GC_free, which tried to reacquire the
- allocator lock, and hence deadlocked. (DBG_HDRS_ALL probably never worked
- with threads?)
- - Fixed several problems with back traces. Accidental references to a free
- list could cause the free list pointer to be overwritten by a back pointer.
- There seemed to be some problems with the encoding of root and finalizer
- references.
-
-Since 6.0alpha7:
- - Changed GC_debug_malloc_replacement and GC_debug_realloc_replacement
- so that they compile under Irix. (Thanks to Dave Love.)
- - Updated powerpc_macosx_mach_dep.s so that it works if the collector
- is in a dynamic library. (Thanks to Andrew Begel.)
- - Transformed README.debugging into debugging.html, updating and
- expanding it in the process. Added gcdescr.html and tree.html
- from the web site to the GC distribution.
- - Fixed several problems related to PRINT_BLACK_LIST. This involved
- restructuring some of the marker macros.
- - Fixed some problems with the sizing of objects with debug information.
- Finalization was broken KEEP_BACK_PTRS or PRINT_BLACK_LIST. Reduced the
- object size with SHORT_DEBUG_HDRS by another word.
- - The "Needed to allocate blacklisted ..." warning had inadvertently
- been turned off by default, due to a buggy test in allchblk.c. Turned
- it back on.
- - Removed the marker macros to deal with 2 pointers in interleaved fashion.
- They were messy and the performance improvement seemed minimal. We'll
- leave such scheduling issues to the compiler.
- - Changed Linux/PowerPC test to also check for __powerpc__ in response
- to a discussion on the gcc mailing list.
- - On Matthew Flatt's suggestion removed the "static" from the jmp_buf
- declaration in GC_generic_push_regs. This was causing problems in
- systems that register all of their own roots. It looks far more correct
- to me without the "static" anyway.
- - Fixed several problems with thread local allocation of pointerfree or
- typed objects. The collector was reclaiming thread-local free lists, since
- it wasn't following the link fields.
- - There was apparently a long-standing race condition related to multithreaded
- incremental collection. A collection could be started and a thread stopped
- between the memory unprotect system call and the setting of the
- corresponding dirt bit. I believe this did not affect Solaris or PCR, which
- use a different dirty-bit implementation. Fixed this by installing
- signal handlers with sigaction instead of signal, and disabling the thread
- suspend signal while in the write-protect handler. (It is unclear
- whether this scenario ever actually occurred. I found it while tracking
- down the following:)
- - Incremental collection did not cooperate correctly with the PARALLEL_MARK
- implementation of GC_malloc_many or the local_malloc primitves. It still
- doesn't work well, but it shouldn't lose memory anymore.
- - Integrated some changes from the gcc source tree that I had previously
- missed. (Thanks to Bryce McKinley for the reminder/diff.)
- - Added Makefile.direct as a copy of the default Makefile, which would
- normally be overwritten if configure is run.
- - Changed the gc.tar target in Makefile.direct to embed the version number
- in the gc directory name. This will affect future tar file distributions.
- - Changed the Irix dynamic library finding code to no longer try to
- eliminate writable text segments under Irix6.x, since that is probably no
- longer necessary, and can apparently be unsafe on occasion. (Thanks to
- Shiro Kawai for pointing this out.)
- - GC_cleanup with GC_DEBUG enabled passed a real object base address to
- GC_debug_register_finalizer_ignore_self, which expected a pointer past the
- debug header. Call GC_register_finalizer_ignore_self instead, even with
- debugging enabled. (Thanks to Jean-Daniel Fekete for catching this.)
- - The collector didn't build with call chain saving enabled but NARGS=0.
- (Thanks to Maarten Thibaut.)
- - Fixed up the GNU-style build files enough so that they work in some
- obvious cases.
- - Added initial port to Digital Mars compiler for win32. (Thanks to Walter
- Bright.)
-
-Since 6.0alpha8:
- - added README.macros.
- - Made gc.mak a symbolic link to work around winzip's tendency to ignore
- hard links.
- - Simplified the setting of NEED_FIND_LIMIT in os_dep.c, possibly breaking
- it on untested platforms.
- - Integrated initial GNU HURD port. (Thanks to Chris Lingard and Igor
- Khavkine.)
- - A few more fixes for Digital Mars compiler (Walter Bright).
- - Fixed gcc version recognition. Renamed OPERATOR_NEW_ARRAY to
- GC_OPERATOR_NEW_ARRAY. Changed GC_OPERATOR_NEW_ARRAY to be the default.
- It can be overridden with -DGC_NO_OPERATOR_NEW_ARRAY. (Thanks to
- Cesar Eduardo Barros.)
- - Changed the byte size to free-list mapping in thread local allocation
- so that size 0 allocations are handled correctly.
- - Fixed Linux/MIPS stackbottom for new toolchain. (Thanks to Ryan Murray.)
- - Changed finalization registration to invoke GC_oom_fn when it runs out
- of memory.
- - Removed lvalue cast in finalize.c. This caused some debug configurations
- not to build with some non-gcc compilers.
-
-Since 6.0alpha9:
- - Two more bug fixes for KEEP_BACK_PTRS and DBG_HDRS_ALL.
- - Fixed a stack clearing problem that resulted in SIGILL with a
- misaligned stack pointer for multithreaded SPARC builds.
- - Integrated another HURD patch (thanks to Igor Khavkine).
-
-Since 6.0:
- - Non-debug, atomic allocations could result in bogus smashed object
- reports with debugging on. (Thanks to Patrick Doyle for the small
- test case.)
- - Fixed GC_get_register_stack_base (Itanium only) to work around a glibc
- 2.2.4 bug.
- - Initial port to HP/UX on Itanium. Thread support and both 32 and 64
- bit ABIs appear to work. Parallel mark support doesn't yet, due to
- some inline assembly code issues. Thread local allocation does appear
- to work.
- - ifdef'ed out glibc2.1/Itanium workaround. I suspect nobody is using
- that combination anymore.
- - Added a patch to make new_gc_alloc.h usable with gcc3.0. (Thanks to
- Dimitris Vyzovitis for the patch.)
- - Debugged 64-bit support on HP/UX PA-RISC.
- - Turned on dynamic loading support for FreeBSD/ELF. (Thanks to Peter
- Housel.)
- - Unregistering of finalizers with debugging allocation was broken.
- (Thanks to Jani Kajala for the test case.)
- - Old finalizers were not returned correctly from GC_debug_register_finalizer.
- - Disabled MPROTECT_VDB for Linux/M68K based on a report that it doesn't work.
- - Cleaned up some statistics gathering code in reclaim.c (Thanks to Walter
- Bright.)
- - Added some support for OpenBSD/ELF/Linux. (Thanks to Suzuki Toshiya.)
- - Added Jakub Jelinek's patch to use dl_iterate_phdr for dynamic library
- traversal to dyn_load.c. Changed it to weakly reference dl_iterate_phdr,
- so that the old code is stilll used with old versions of glibc.
- - Cleaned up feature test macros for various threads packages and
- integrated (partially functional) FreeBSD threads code from Loren Rittle.
- It's likely that the cleanup broke something, since it touched lots of
- code. It's also likelly that it fixed some unreported bugs in the
- less common thread implementations, since some of the original code
- didn't stand up to close scrutiny. Support for the next pthreads
- implementation should be easier to add.
-
-Since 6.1alpha1:
- - No longer wrap read by default in multithreaded applications. It was
- pointed out on the libgcj list that this holds the allocation lock for
- way too long if the read blocks. For now, reads into the heap are
- broken with incremental collection. It's possible to turn this back on
- if you make sure that read calls don't block (e.g. by calling select
- first).
- - Fix ifdef in Solaris_threads.h to refer to GC_SOLARIS_THREADS.
- - Added check for environment variable GC_IGNORE_GCJ_INFO.
- - Added printing of stop-the-world GC times if GC_PRINT_STATS environment
- variable is set.
- - The calloc definition in leak_detector.h was missing parentheses, and
- realloc was missing a second argument to GC_REALLOC.
- (Thanks to Elrond (elrond<at>samba-tng.org).)
- - Added GC_PRINT_BACK_HEIGHT environment variable and associated
- code, mostly in the new file backgraph.c. See doc/README.environment.
- - Added -DUSE_GLOBAL_ALLOC to work around a Windows NT issue. (Thanks to
- Jonathan Clark.)
- - Integrated port to NEC EWS4800 (MIPS-based workstation, with somewhat
- different address-space layout). This may help for other machines with
- holes in the data segment. (Thanks to Hironori Sakamoto.)
- - Changed the order in which GC_push_roots and friends push things onto
- the mark stack. GC_push_all calls need to come first, since we can't
- necessarily recovere if those overflow the mark stack. (Thanks to
- Matthew Flatt for tracking down the problem.)
- - Some minor cleanups to mostly support the Intel compiler on Linux/IA64.
-
-Since 6.1 alpha2:
- - Minor cleanup on the gcconfig.h section for SPARC.
- - Minor fix to support Intel compiler for I386/Linux. (Thanks to Sven
- Hartrumpf.)
- - Added SPARC V9 (64-bit) support. (Thanks to Jeff Sturm.)
- - Restructured the way in which we determine whether or not to keep
- call stacks for debug allocation. By default SAVE_CALL_COUNT is
- now zero on all platforms. Added SAVE_CALL_NARGS parameters.
- If possible, use execinfo.h to capture call stack. (This should
- add support for a number of new platforms, though often at
- considerable runtime expense.)
- - Try to print symbolic information for call stacks. On Linux, we
- do this with a combination of execinfo.h and running addr2line in
- a separate process. This is both much more expensive and much more
- useful. Amazingly, it seems to be fast enough for most purposes.
- - Redefined strdup if -DREDIRECT_MALLOC is given.
- - Changed incremental collector and MPROTECT_VDB implementation so that,
- under favorable conditions, pointerfree objects are not protected.
- Added GC_incremental_protection_needs() to determine ahead of time whether
- pointerfree objects may be protected. Replaced GC_write_hint() with
- GC_remove_protection().
- - Added test for GC_ENABLE_INCREMENTAL environment variable.
- - Made GC_time_limit runtime configurable. Added GC_PAUSE_TIME_TARGET
- environment variable.
- - Eliminated GC_page_sz, a duplicate of GC_page_size.
- - Caused the Solaris and Irix thread creation primitives to call
- GC_init_inner().
-
-Since 6.1alpha3:
- - Fixed typo in sparc_mach_dep.S, preventing the 64-bit version from
- building. Increased 64-bit heap size limit in test.c slightly, since
- a functional SPARC collector seems to slightly exceed the old limits.
- (Thanks again to Jeff Sturm.)
- - Use NPRGREG in solaris_threads.c, thus printing all registers if things
- go wrong.
- - Added GC_MARKERS environment variable to allow use of a single marker
- thread on an MP without confusing the lock implementation.
- - Collect much less aggressively in incremental mode with GC_TIME_UNLIMITED.
- This is really a purely generational mode, and we can afford to
- postpone the collection until the heap is (nearly) full.
- - Remove read() wrapper for MPROTECT_VDB. It was causing more harm than
- good. It is often no longer needed if system calls avoid writing to
- pointerfull heap objects.
- - Fix MACOSX test in gcconfig.h. (Thanks to John Clements.)
- - Change GC_test_and_set so that it consistently has one argument.
- Add spaces to ::: in powerpc assembly code in gc_locks.h.
- (Thanks to Ryan Murray.)
- - Fixed a formatting error in dbg_mlc.c. Added prototype to GC_abort()
- declaration. (Thanks to Michael Smith.)
- - Removed "source" argument to GC_find_start(). Eliminate GC_FIND_START().
- - Added win32 recognition code in configure.in. Changed some of the
- dllimport/export defines in gc.h. (Thanks to Adam Megacz.)
- - GC_malloc_many didn't set hb_last_reclaimed when it called
- GC_reclaim_generic. (I'm not sure this matters much, but ...)
- - Allocating uncollectable objects with debug information sometimes
- allocated objects that were one byte too small, since uncollectable
- objects don't have the extra byte added at the end. (Thanks to
- Wink Saville for pointing this out.)
- - Added a bit more assertion checking to make sure that gcj objects
- on free lists never have a nonzero second word.
- - Replaced BCC_MAKEFILE with an up-to-date one. (Thanks to
- Andre Leiradella.)
- - Upgraded libtool, cinfigure.in and some related files to hopefully
- support NetBSD/SPARC. (Thanks to Adrian Bunk.) Unfortunately,
- libtool 1.4.2 seemed to be buggy due to missing quotes in several
- "test" invocations. Fixed those in the ltmain.sh script.
- - Some win32-specific patches, including the introduction of
- GC_CreateThread. (Thanks to Adam Megacz.)
- - Merged in gcj changes from Anthony Green to support embedded systems.
- - Tried to consistently rename preprocessed assembly files with a capital
- .S extension.
- - Use alpha_mach_dep.S on ALPHA again. It doesn't really matter, but this
- makes our distribution consistent with the gcc one, avoiding future merge
- problems.
- - Move GET_MEM definition into gcconfig.h. Include gcconfig.h slightly
- later in gc_priv.h to avoid forward references to ptr_t.
- - Add some testing of local allocation to test.c.
- - Change definition of INVALID_QTID in specific.h. The -1 value was used
- inconsistently, and too likely to collide with a valid stack address.
- Some general clean-up of specific.[ch]. Added assertions. (Thanks
- to Michael Smith for tracking down an intermittent bug to this
- general area. I'm not sure it has been squashed yet, however.)
- - On Pthread systems it was not safe to call GC_malloc() between fork()
- and exec(). According to the applicable standards, it doesn't appear
- to be safe to call malloc() or many other libc functions either, thus
- it's not clear this is fixable. Added experimental support for
- -DHANDLE_FORK in linux_threads.c which tries to support it. It may
- succeed if libc does the right thing. I'm not sure whether it does.
- (Thanks to Kenneth Schalk for pointing out this issue.)
- - Documented thread local allocation primitives to require an
- explicit GC_init call. GC_init_parallel is no longer declared to
- be a constructor function, since that isn't portable and often
- seems to lead to initialization order problems.
- - Changed gc_cpp.cc and gc_cpp.h in one more attempt to make them
- compatible with Visual C++ 6. (Thanks to Wink Saville for the
- patch.)
- - Some more patches for Linux on HP PA-RISC.
- - Added include/gc_allocator.h. It implements (hopefully) standard
- conforming (as opposed to SGI-style) allocators that allocate
- collectable (gc_allocator) or GC-traceable, but not collectable
- (traceable_allocator) objects. This borrows heavily from libstc++,
- which borrows heavily from the SGI implementation, this part of
- which was written by Matt Austern. Changed test_cpp.cc to very
- minimally test this.
- - On Linux/X86, retry mmap with a different start argument. That should
- allow the collector to use more (closer to 3GB) of the address space.
- (Thanks to Jeffrey Mark Siskind for tracking this down.)
- - Force 64 bit alignment with GCJ support. (Reflects Bryce McKinley's
- patch to the gcc tree.)
- - Refined the choice of sa_handler vs. sa_sigaction in GC_dirty_init
- to accomodate some glibc5 systems. (Thanks to Dan Fandrich for the
- patch.)
- - Compensated for the fact that current versions of glibc set
- __libc_stack_end incorrectly on Linux/IA64 while initialization code
- is running. This could cause the collector to miss 16 bytes of
- the memory stack if GC_malloc or friends where called before main().
- - Mostly integrated Takis Psarogiannakopoulos' port to DG/UX Inix 86.
- This will probably take another iteration to work, since his
- patch conflicted with the libtool upgrade.
- - Added README.arm.cross containing some information about cross-
- compiling to an ARM processor from Margaret Fleck.
-
-Since 6.1alpha4:
- - Added GC_finalizer_mem_freed, and changed some of the code that
- decided on heap expansion to look at it. Memory explicitly
- deallocated by finalizers essentially needs to be counted as reclaimed
- by the GC. Otherwise there are cases in which the heap can grow
- unboundedly. (Thanks to Mark Reichert for the test case.)
- - Integrated Adam Megacz patches to not scan dynamic libraries if
- we are compiling with gcc on win32. Otherwise we need structured
- exception handling to deal with asynchronously unmapped root
- segments, and gcc doesn't directly support that.
- - Integrated Anthony Green's patch to support Wine.
- - GC_OPERATOR_NEW_ARRAY was misspelled OPERATOR_NEW_ARRAY in several
- places, including gc_cpp.cc. (Thanks to Wink Saville for pointing
- this out.)
- - Integrated Loren James Rittle's Alpha FreeBSD patches. In
- response to Richard Henderson's suggestion, these also
- changed the declarations of symbols like _end on many platforms to
- that they wouldn't mistakenly be declared as short data symbols.
- - Integrated changes from the Debian distribution. (Thanks to Ryan Murray
- for pointing these out.) Fix C++ comments in POWERPC port. Add ARM32
- incremental GC support. Get rid of USE_GENERIC_PUSH_REGS for alpha/Linux,
- this time for real. Use va_copy to get rid of cord printf problems
- (finally).
- - Close file descriptor used to count cpus. Thanks to Jeff Sturm for
- pointing out the omission.
- - Don't just drop gcj free lists in GC_start_reclaim, since that can
- eventually cause the marker to see a bogus mark descriptor in the
- dropped objects. The usual symptom was a very intermittent segmentation
- fault in the marker. This mattered only if one of the GC_gcj_malloc
- variants was used. (Thanks to Michael Smith, Jeff Sturm, Bryce
- McKinley and Tom Tromey for helping to track this down.)
- - Fixed Linux and Solaris/64 SPARC configuration. (Thanks to David Miller,
- Jeff Sturm, Tom Tromey, and Christian Joensson.)
- - Fixed a typo in strdup definition. (Thanks to Gerard A Allan.)
- - Changed Makefile.direct to invoke $(CC) to assemble alpha_mach_dep.S.
- This is needed on Linux. I'm not sure whether it's better or worse
- on Tru64.
- - Changed gc_cpp.h once more to declare operator new and friends only in
- a Microsoft environment. This may need further fine tuning. (Thanks to
- Johannes Schmidt for pointing out that the older code breaks on gcc3.0.4.)
- - Don't ever override strdup if it's already macro defined. (Thanks to
- Adnan Ali for pointing out the problem.)
- - Changed gc_cpp.h yet again to also overload placement new. Due to the
- C++ overloading rules, the other overloaded new operations otherwise hide
- placement new, which causes many STL uses to break. (Thanks to Reza
- Shahidi for reporting this, and to Matt Austern for proposing a fix.)
- - Integrated cygwin pthreads support from Dan Bonachea.
- - Turn on DYNAMIC_LOADING for NetBSD. (Thanks to Krister Walfridsson.)
- - Changed printing code to print more complete GC times.
- - Applied Mark Mitchell's Irix patch to correct some bitrot.
- - Clarified which object-printing routines in dbg_mlc.c should hold
- the allocation lock. Restructured the code to allow reasonable object
- printing with -DREDIRECT_MALLOC.
- - Fix the Linux mmap code to always start with 0x1000 as the initial hint.
- Minor patches for 64-bit AIX, particularly to STACKBOTTOM.
- (Thanks again to Jeffrey Mark Siskind.)
- - Renamed "SUSPENDED" flag for Solaris threads support to avoid a conflict
- with a system header. (Thanks to Philp Brown.)
- - Cause win32_threads.c to handle an out of range stack pointer correctly,
- though currently with a warning. (Thanks to Jonathan Clark for
- observing that win32 applications may temporarily use the stack
- pointer for other purposes, and suggesting a fix. Unfortunately, it's
- not clear that there is a complete solution to this problem.)
-
-Since 6.1alpha5:
- - Added GC_MAXIMUM_HEAP_SIZE environment variable.
- - Fix configure.in for MIPS/LINUX. (Thanks to H.J. Lu.)
- - Double page hash table size for -DLARGE_CONFIG.
- - Integrated Bo Thorsen's X86-64 support.
- - STACKBOTTOM definition for LINUX/MIPS was partially changed back.
- (Thanks to H.J. Lu and Hiroshi Kawashima for resolving this.)
- - Replaced all occurrences of LINUX_DATA_START in gcconfig.h with
- SEARCH_FOR_DATA_START. It doesn't hurt to falll back to a search.
- And __data_start doesn't seem to get defined correctly of the GC
- library is loaded with LD_PRELOAD, e.g. for leak detection.
- - If the GC_find_leak environment variable is set, do a
- atexit(GC_gcollect) to give us at least one chance to detect leaks.
- This may report some very benign leaks, but ...
- - Addeded REDIRECT_FREE. It's necessary if we want leak detection with
- LD_PRELOAD.
- - Defer printing of leaked objects, as for smashed objects.
- - Fixed process and descriptor leak in GC_print_callers. Try for
- line number even if we got function name.)
- - Ported parallel GC support and thread local allocation to Alpha.
- Not yet well-tested.
- - Added GC_DUMP_REGULARLY and added finalization statistics to GC_dump().
- - Fixed Makefile.am to mention alpha_mach_dep.S instead of the defunct
- alpha_mach_dep.s. (Thanks to Fergus Henderson.)
- - Incorporated a change to new_gc_alloc.h, suggested by Johannes Schmidt,
- which should make it work with gcc3.1. (I would still like to encourage
- use of gc_allocator.h instead.)
- - Use alpha_mach_dep.S only on Linux. (It's not clear that this is
- optimal, but it otherwise didn't build on Tru64. Thanks to Fergus
- Henderson.)
- - Added ifdef to guard free() in os_dep.c. Otherwise we get a
- compilation error on Irix. (Thanks to Dai Sato.)
- - Added an experimental version of GC_memalign to mallocx.c. This can't
- always work, since we don't handle alignment requests in the hblk-level
- allocator, and we can't handle arbitrary pointer displacements unless
- GC_all_interior_pointers is enabled. But it should work for alignment
- requests up to HBLKSIZE. This is not yet documented in the standard
- places.
- - Finally debugged the OSF1/Tru64 thread support. This needs more testing,
- since I needed to add a somewhat unconvincing workaround for signal
- delivery issues that I don't yet completely understand. But it does
- pass my tests, even in parallel GC mode. Incremental GC support is
- disabled if thread support is enabled, due to the signal issues.
- - Eliminated name-space-incorrect definition of _cdecl from gc_cpp.h.
- - Added GC_debug_malloc_replacement and GC_debug_realloc_replacement
- declarations to gc.h. On IA64, this is required for REDIRECT_MALLOC
- to work correctly with these.
- - Fixed Linux USE_PROC_FOR_LIBRARIES to work with a 64-bit /proc format.
-
-Since 6.1:
- - Guard the test for GC_DUMP_REGULARLY in misc.c with
- "#ifndef NO_DEBUGGING". Otherwise it fails to build with NO_DEBUGGING
- defined. (Thanks to Manuel Serrano.)
- - Message about retrying suspend signals was incorrectly generated even when
- flag was not set.
- - Cleaned up MACOSX/NEXT root registration code. There was apparently a
- separate ifdef case in GC_register_data_segments() for no reason.
- - Removed MPROTECT_VDB for MACOSX port, based on one negative report.
- - Arrange for gc.h and friends to be correctly installed with GNU-style
- "make install".
- - Enable the GNU-style build facility include C++ support in the library
- with --enable-cplusplus. (Thanks to Thomas Maier for some of the patch.)
- - Mark from GC_thread_key in linux_threads.c, in case that's allocated
- from the garbage collected heap, as it is with our own thread-specific
- storage implementation. (Thanks to Jeff Sturm.)
- - Mark all free list header blocks if they are heap allocated. This avoids
- some unnecessary tracing. And it remains correct if we clear the
- root set. (Thanks to Jeff Sturm for identifying the bug.)
- - Improved S390/Linux support. Add S390/Linux 64-bit support. (Thanks
- to Ulrich Weigand.)
- - Corrected the spelling of GC_{M,C}ALLOC_EXPLICTLY_TYPED to
- GC_{M,C}ALLOC_EXPLICITLY_TYPED in gc_typed.h. This is technically
- an interface change. Based on the fact that nobody reported this,
- I suspect/hope there were no clients.
- - Cleaned up gc_typed.h so that (1) it adds an extern "C" declaration
- when appropriate, (2) doesn't generate references to undefined internal
- macros, and (3) allows easier manual construction of descriptors.
- - Close the file descriptor used by GC_print_address_map().
- - Set the "close-on-exec" bit for various file descriptors maintained
- for the collector's internal use.
- - Added a hack to find memory segments owned by the system allocator
- under win32. Based on my tests, this tends to eventually find all
- segments, though it may take a while. There appear to be cleaner,
- but slower solutions under NT/XP. But they rely on an API that's
- unsupported under 9X.
- - Changed Linux PowerPC stack finding to LINUX_STACKBOTTOM. (Thanks
- to Akira Tagoh for pointing out that HEURISTIC1 doesn't work on
- 64-bit kernels.)
- - Added GC_set_free_space_divisor to avoid some Windows dll issues.
- - Added FIXUP_POINTER, POINTER_SHIFT, POINTER_MASK to allow preprocessing
- of candidate pointers for tagging, etc.
- - Always lock around GC_notify_full_gc(). Simplified code for
- invoking GC_notify_full_gc().
- - Changed the way DATASTART is defined on FreeBSD to be robust against
- an unmapped page after etext. (Thanks to Hironori Sakamoto for
- tracking down the intermittent failure.)
- - Made GC_enable() and GC_disable() official. Deprecated direct update
- of GC_dont_gc. Changed GC_gcollect to be a noop when garbage collection
- is disabled.
- - Call GC_register_dynamic_libraries before stopping the world on Linux,
- in order to avoid a potential deadlock due to the dl_iterate_phdr lock.
- - Introduced a more general mechanism for platform-dependent code to
- decide whether the main data segment should be handled separately
- from dynamic libraries, or registered by GC_register_dynamic_libraries.
- The latter is more reliable and easier on Linux with dl_iterate_phdr.
-
-Since 6.2alpha1:
- - Fixed the completely broken FreeBSD code in 6.2alpha1. (Thanks to
- Hironori Sakamoto for the patch.)
- - Changed IRIX reference in dbg_mlc.c to IRIX5. (Thanks to Marcus Herbert.)
- - Attempted to work around the problems with .S filenames and the SGI
- compiler. (Reported by several people. Untested.)
- - Worked around an HP/UX make issue with the GNU-style build process.
- - Fixed the --enable-cplusplus build machinery to allow builds without
- a C++ compiler. (That was always the intent ...)
- - Changed the debugging allocation macros to explicitly pass the return
- address for Linux and XXXBSD on hardware for which we can't get stack
- traces. Use __builtin_return_address(0) to generate it when possible.
- Some of the configuration work was cleaned up (good) and moved to gc.h
- (bad, but necessary). This should make leak detection more useful
- on a number of platforms. (Thanks to Fabian Thylman for the suggestion.)
- - Fixed compilation problems in dbg_mlc.c with GC_ADD_CALLER.
- - Bumped revision number for dynamic library.
-
-Since 6.2alpha2:
- - Don't include execinfo.h in os_dep.c when it's not needed, and may not exist.
-
-Since 6.2alpha3:
- - Use LINUX_STACKBOTTOM for >= glibc2.2 on Linux/MIPS. (See Debian bug
- # 177204)
- - Integrated Jeff Sturm and Jesse Rosenstock's MACOSX threads patches.
- - Integrated Grzegorz Jakacki's substantial GNU build patch. "Make dist"
- should now work for the GNU build process. Documentation files
- are installed under share/gc.
- - Tweaked gc_cpp.h to again support the Borland compiler. (Thanks to
- Rene Girard for pointing out the problems.)
- - Updated BCC_MAKEFILE (thanks to Rene Girard).
- - Added GC_ASSERT check for minimum thread stack size.
- - Added --enable-gc-assertions.
- - Added some web documentation to the distribution. Updated it in the
- process.
- - Separate gc_conf_macros.h from gc.h.
- - Added generic GC_THREADS client-defined macro to set the appropriate
- GC_XXX_THREADS internal macro. (gc_config_macros.h.)
- - Add debugging versions of _ignore_off_page allocation primitves.
- - Moved declarations of GC_make_closure and GC_debug_invoke_finalizer
- from gc.h to gc_priv.h.
- - Reset GC_fail_count even if only a small allocation succeeds.
- - Integrated Brian Alliet's patch for dynamic library support on Darwin.
- - gc_cpp.h's gc_cleanup destructor called GC_REGISTER_FINALIZER_IGNORE_SELF
- when it should have called the lower case version, since it was
- explicitly computing a base pointer.
-
-Since 6.2alpha4:
- - GC_invoke_finalizers could, under rare conditions, set
- GC_finalizer_mem_freed to an essentially random value. This could
- possibly cause unbounded heap growth for long-running applications
- under some conditions. (The bug was introduced in 6.1alpha5, and
- is not in gcc3.3. Thanks to Ben Hutchings for finding it.)
- - Attempted to sanitize the various DLL macros. GC_USE_DLL disappeared.
- GC_DLL is used instead. All internal tests are now on GC_DLL.
- README.macros is now more precise about the intended meaning.
- - Include DllMain in the multithreaded win32 version only if the
- collector is actually built as a dll. (Thanks to Mohan Embar for
- a version of the patch.)
- - Hide the cygwin threadAttach/Detach functions. They were violating our
- namespace rules.
- - Fixed an assertion in GC_check_heap_proc. Added GC_STATIC_ASSERT.
- (Thanks again to Ben Hutchings.)
- - Removed some obsolete definitions for Linux/PowerPC in gcconfig.h.
- - CORD_cat was not rebalancing unbalanced trees in some cases, violating
- a CORD invariant. Also tweaked the rebalancing rule for
- CORD_cat_char_star. (Thanks to Alexandr Petrosian for the bug report
- and patch.)
- - Added hand-coded structured exception handling support to mark.c.
- This should enable support of dynamic libraries under win32 with
- gcc-compiled code. (Thanks to Ranjit Mathew for the patch.)
- Turned on dynamic library scanning for win32/gcc.
- - Removed some remnants of read wrapping. (Thanks to Kenneth Schalk.)
- GC_USE_LD_WRAP ws probably broken in recent versions.
- - The build could fail on some platforms since gcconfig.h could include
- declarations mentioning ptr_t, which was not defined, e.g. when if_mach
- was built. (Thanks to Yann Dirson for pointing this out.) Also
- cleaned up tests for GC_PRIVATE_H in gcconfig.h a bit.
- - The GC_LOOP_ON_ABORT environment variable interfered with incremental
- collection, since the write fault handler was erroneously overridden.
- Handlers are now set up in the correct order.
- - It used to be possible to call GC_mark_thread_local_free_lists() while
- the world was not stopped during an incremental GC. This was not safe.
- Fortunately, it was also unnecessary. Added GC_world_stopped flag
- to avoid it. (This caused occasional crashes in GC_set_fl_marks
- with thread local allocation and incremental GC. This probably happened
- primarily on old, slow multiprocessors.)
- - Allowed overriding of MAX_THREADS in win32_threads.c from the build
- command line. (Patch from Yannis Bres.)
- - Taught the IA64/linux code to determine the register backing store base from
- /proc/self/maps after checking the __libc symbol, but before guessing.
- (__libc symbols are on the endangered list, and the guess is likely to not
- always be right for 2.6 kernels.) Restructured the code to read and parse
- /proc/self/maps so it only exists in one place (all platforms).
- - The -DUSE_PROC_FOR_LIBRARIES code was broken on Linux. It claimed that it
- also registered the main data segment, but didn't actually do so. (I don't
- think anyone actually uses this configuration, but ...)
- - Made another attempt to get --enablecplusplus to do the right thing.
- Since there are unavoidable problems with C programs linking against a
- dynamic library that includes C++ code, I separated out the c++ code into
- libgccpp.
-
-Since 6.2alpha5:
- - There was an extra underscore in the name of GC_save_registers_in_stack
- for NetBSD/SPARC. (Thanks to Jaap Boender for the patch.)
- - Integrated Brian Alliet's patch for Darwin. This restructured the
- linuxthreads/pthreads support to separate generic pthreads support
- from more the system-dependent thread-stopping code. I believe this
- should make it easier to eliminate the code duplication between
- pthreads platforms in the future. The patch included some other
- code cleanups.
- - Integrated Dan Bonachea's patch to support AIX threads. This required
- substantial manual integration, mostly due to conflicts with other
- recent threads changes. It may take another iteration to
- get it to work.
- - Removed HPUX/PA-RISC support from aix_irix_threads.c. It wasn't used
- anyway and it cluttered up the code. And anything we can do to migrate
- towards generic pthreads support is a good thing.
- - Added a more explicit test for tracing of function arguments to test.c.
- (Thanks to Dan Grayson.)
- - Added Akira Tagoh's PowerPC64 patch.
- - Fixed some bit rot in the Cygwin port. (Thanks to Dan Bonachea for
- pointing it out.) Gc.h now includes just windows.h, not winbase.h.
- - Declared GC_save_regs_in_stack() in gc_priv.h. Remove other declarations.
- - Changed --enable-cplusplus to use automake consitionals. The old way
- confused libtool. "Make install" didn't work correctly for the old version.
- Previously --enable-cplusplus was broken on cygwin.
- - Changed the C version of GC_push_regs to fail at compile time if it is
- generated with an empty body. This seems to have been the cause of one
- or two subtle failures on unusual platforms. Those failures should
- now occur at build time and be easily fixable.
-
-Since 6.2alpha6:
- - Integrated a second round of Irix/AIX patches from Dan Bonachea.
- Renamed mips_sgi_mach_dep.S back to mips_sgi_mach_dep.s, since it requires
- the Irix assembler to do the C preprocessing; gcc -E doesn't work.
- - Fixed Makefile.direct for DARWIN. (Thanks to Manuel Serrano.)
- - There was a race between GC_pthread_detach and thread exit that could
- result in a thread structure being deallocated by GC_pthread_detach
- eventhough it was still needed by the thread exit code. (Thanks to
- Dick Porter for the small test case that allowed this to be debugged.)
- - Fixed version parsing for non-alpha versions in acinclude.m4 and
- version checking in version.h.
-
-Since 6.2:
- - Integrated some NetBSD patches forwarded to me by Marc Recht. These
- were already in the NetBSD package.
- - GC_pthread_create waited for the semaphore even if pthread_create failed.
- Thanks to Dick Porter for the pthread_support.c patch. Applied the
- analogous fix for aix_irix_threads.c.
- - Added Rainer Orth's Tru64 fixes.
- - The check for exceeding the thread table size in win32 threadDetach
- was incorrect. (Thanks to Alexandr Petrosian for the patch.)
- - Applied Andrew Begel's patch to correct some reentrancy issues
- with dynamic loading on Darwin.
- - GC_CreateThread() was neglecting to duplicate the thread handle in
- the table. (Thanks to Tum Nguyen for the patch.)
- - Pass +ESdbgasm only on PA-RISC machines with vendor compiler.
- (Thanks to Roger Sayle for the patch.)
- - Applied more AIX threads patches from Scott Ananian.
-
-Since 6.3alpha1:
- - Reenabled I_HOLD_LOCK assertion in aix_irix_threads.h.
- - Put back the WINABI qualifier for GC_CreateThread. (Thanks to
- Danny Smith for the patch. 6.3alpha1 had the qualifier in one place
- but not elsewhere, which was clearly wrong.)
- - Sometimes explicitly define __private_extern__ before DARWIN dyld.h
- include. (Thanks to Andreas Tobker for postting the patch.)
- - Included signal.h from pthread_support.c. Removed GC_looping_handler,
- which was dead code.
- - GC_find_start was misdeclared by gc_pmark.h if PRINT_BLACK_LIST was
- defined. (Thanks to Glauco Masotti for testing and reporting this.)
- Changed GC_find_start to never just return 0. According to its
- comment it doesn't, and it's unclear that's correct.
- - GC_alloc_large had several largely compensating bugs in the
- computation of GC_words_wasted. (It was confused about bytes vs.
- words in two places.)
- - Integrated Slava Sysoltev's patch to support more recent versions of
- the Intel compiler on IA64/Linux.
- - Changed win32 spinlock initialization to conditionally set a spin count.
- (Emmanual Stumpf pointed out that enabling this makes a large performance
- difference on win32 multiprocessors.) Also cleaned up the win32 spinlock
- initialization code a bit.
- - Fixed thread support for HP/UX/IA64. The register backing store base for
- the main thread was sometimes not set correctly. (Thanks to Laurent
- Morichetti.)
- - Added -DEMPTY_GETENV_RESULTS flag to work around Wine problem.
- - Declare GC_stack_alloc and GC_stack_free in solaris_threads.h to
- avoid 64-bit size mismatches. (Thanks to Bernie Solomon.)
- - Fixed GC_generic_push_regs to avoid a potential and very unfortunate
- tail call optimization. This could lead to prematurely reclaimed
- objects on configurations that used the generic routine and the new
- build infrastructure (which potentially optimizes mach_dep.c).
- This was a serious bug, but it's unclear whether it has resulted in
- any real failures.
- - Fixed CORD_str to deal with signed characters. (Thanks to Alexandr
- Petrosian for noticing the problem and supplying the patch.)
- - Merged a couple of NOSYS/ECOS tests into os_dep.c from gcj. (Thanks
- to Anthony Green.)
- - Partially merged a win32 patch from Ben Hutchings, and substantially
- revised other parts of win32_threads.c. It had several problems.
- Under MinGW with a statically linked library, the main thread was
- not registered. Cygwin detached threads leaked thread descriptors.
- There were several race conditions. For now, unfortunately the
- static threads limit remains, though we increased it, and made table
- traversal cost depend on the actual thread count.
- There is also still some code duplication with pthread_support.c.
- (Thread descriptors did become much smaller, since Ben Hutchings
- removed the thread context from them.)
- - Integrated a Solaris configure.in patch from Rainer Orth.
- - Added GC_IGNORE_FB and associated warning to very partially address
- the issue of the collector treating a mapped frame buffer as part
- of the root set. (Thanks to David Peroutka for providing some
- insight. More would be helpful. Is there anything that can be used
- to at least partially identify such memory segments?)
-
-Since 6.3alpha2:
- - Removed -DSMALL_CONFIG from BCC_MAKEFILE.
- - Changed macros to test for an ARM processor (Patch from Richard Earnshaw.)
- - Mostly applied a DJGPP patch from Doug Kaufman. Especially Makefile.dj
- had suffered from serious bit rot.
- - Rewrote GC_apply_to_maps, eliminating an off-by-one subscript error,
- and a call to alloca (for lcc compatibility).
- - Changed USE_MUNMAP behavior on posixy platforms to immediately remap
- the memory with PROT_NONE instead of unmapping it. The latter risks
- an intervening mmap grabbing the address space out from underneath us.
- Updated this code to reflect a cleaner patch from Ulrich Drepper.
- - Replaced _T with _Tp in new_gc_alloc.h to avoid a MACOS X conflict.
- (Patch from Andrew Begel.)
- - Dynamically choose whether or not lock should spin on win32. (Thanks
- to Maurizio Vairani for the patch.) This may be a significant performance
- improvement for win32.
- - Fix Makefile.direct to actually include NT_STATIC_THREADS_MAKEFILE
- in the distribution. (Again thanks to Maurizio Vairani.)
- - Maybe_install_looping_handler() was accidentally exported, violating
- our name space convention.
- - Made os_dep.c use sigsetjmp and SA_NODEFER for NetBSD. (Thanks to
- Christian Limpach.) (I generalized the patch to use sigsetjmp on all
- UNIX_LIKE platforms, admittedly a slightly risky move. But it may avoid
- similar problems on some other platforms. I also cleaned up the defn
- of UNIX_LIKE a bit. - Hans)
- - Integrated Andrew Begel's Darwin threads patch, adjusted according to
- some of Fergus Hendersons's comments. (Patch didn't apply cleanly,
- errors are possible.)
- - Added another test or two for the Intel 8.0 compiler to avoid
- confusing it with gcc. The single-threaded collector should now build
- with icc, at least on ia64.
-
-Since 6.3alpha3:
- - USE_MMAP was broken by confusion in the code dealing with USE_MMAP_ANON.
- (This was pointed out, and fixes were suggested by several other people.)
- - Darwin supprt was broken in alpha3 as a result of my misintegration of
- Andrew Begel's patches. Fixed with another patch from Andrew Begel.
- - A new sanity check in pthread_stop_world.c:GC_push_all_stacks() was
- overly aggressive. We may collect from an unregistered thread during
- thread creation. Fixed by explicitly checking for that case. (Added
- GC_in_thread_creation.)
-
-Since 6.3alpha4:
- - Fix & vs && typo in GC_generic_malloc and
- GC_generic_malloc_ignore_off_page. (Propagated from the gcc tree.)
- - Removed SA_NODEFER hack from NetBSD and Solaris write-protect handler.
- (According to Christian Limpach, the NetBSD problem is fixed.
- Presumably so is the Solaris 2.3 problem.)
- - Removed placement delete from gc_cpp.h for the SGI compiler.
- (Thanks to Simon Gornall for the patch.)
- - Changed semantics of the GC_IGNORE_FB environment variable, based
- on experimentation by Nicolas Cannasse pointing out that the old
- interpretation was useless. We still need help in identifying win32
- graphics memory mappings. The current "solution" is a hack.
- - Removed "MAKEOVERRIDES =" from Makefile.am and thus Makefile.in.
- It probably made more sense in the gcc context.
- - Explicitly ensure that NEED_FIND_LIMIT is defined for {Open,Net}BSD/ELF.
- - Replaced USE_HPUX_TLS macro by USE_COMPILER_TLS, since gcc often
- supports the same extension on various platforms.
- - Added some basic (completely untested) defines for win64, in support
- of future work.
- - Declared GC_jmp_buf in os_dep.s as JMP_BUF instead of jmp_buf, fixing
- a memory overwrite bug on Solaris and perhaps other platforms.
- - Added 0 != __libc_stack_end test to GC_linux_stack_base. (Thanks to Jakub
- Jelinek, both for the patch, and for explaining the problem to me.)
- Otherwise "prelink"ing could cause the collector to fail.
- - Changed default thread local storage implementation to USE_PTHREAD_SPECIFIC
- for HP/UX with gcc. The compiler-based implementation appears to work
- only with the vendor compiler.
- - Export GC_debug_header_size and GC_USR_PTR_FROM_BASE from gc_mark.h,
- making client mark code cleaner and less dependent on GC version.
- - Export several new procedures and GC_generic_malloc from gc_mark.h
- to support user-defined kinds. Use the new procedures to replace existing
- code in gcj_mlc.c and typd_mlc.c.
- - Added support for GC_BACKTRACES.
- - Fixed a remaining problem in CORD_str with signed characters. (Thanks
- to Alexandr Petrosian for the patch.)
- - Removed supposedly redundant, but very buggy, definitions of finalizer
- macros from javaxfc.h. Fortunately this file probably has no users.
- The correct declarations were already in gc.h.
- - Also need to set GC_in_thread_creation while waiting for GC during
- thread termination, since it is also possible to collect from an
- unregistered thread in that case.
- - Define NO_GETENV for Windows CE, since getenv doesn't appear to exist.
- + some other minor WinCE fixes. (Thanks to Alain Novak.)
- - Added GC_register_describe_type_fn.
- - Arrange for debugging finalizer registration to ignore non-heap
- registrations, since the regular version of the routine also behaves
- that way.
- - GC_gcj_malloc and friends need to check for finalizers waiting to be run.
- One of the more obscure allocation routines with missing a LOCK() call.
- - Fixed cvtres invocations in NT_MAKEFILE and NT_STATIC_THREADS_MAKEFILE
- to work with VS.NET.
- - Cleaned up GC_INIT calls in test. Updated gc.man to encourage GC_INIT
- use in portable code.
- - Taught the GC to use libunwind if --enable-full-debug is specified on
- IA64 and libunwind is present.
- - The USE_MUNMAP code could get confused about the age of a block and
- prematurely unmap it. GC_unmap_old had a bug related to wrapping of
- GC_gc_no. GC_freehblk and GC_merge_unmapped didn't maintain
- hb_last_reclaimed reasonably when blocks were merged. The code was
- fixed to reflect original intent, but that may not always be an
- improvement. See todo list item.
-
-Since 6.3alpha5:
- - Define USE_GENERIC_PUSH_REGS for NetBSD/M68K.
- - Fixed the X86_64 PREFETCH macros to correctly handle ia32e (which uses
- different prefetch instructions from AMD64). (Thanks to H.J. Lu.)
- - GC_config_macros.h did not correctly define GC_WIN32_THREADS from
- GC_THREADS.
- - Added simple_example.html.
- - Merged Andrew Gray's patch to correctly restore signal handlers on
- FreeBSD.
- - Merged a patch from Andreas Jaeger to deal with prefetch-related warnings
- on x86-64. Added some other casts so that the PREFETCH macros
- always get a ptr_t argument. Removed some casts inthe PREFETCH
- implementations.
- - At Jesse Jones suggestion: Added a header guard for gc_allocator.h
- and changed GC_debug_free to clobber contents of deallocated object.
- - The signal masking code in pthread_stop_world.c contained some errors.
- In particular SIGSEGV was masked in the handler, in spite of the fact that
- it wrote to the heap. This could lead to an uncaught SIGSEGV, which
- apparently became much more likely in Linux 2.6. Also fixed some
- typos, and reduced code duplication in the same area.
- - Remove ltconfig, clean up configure messages for DGUX (thanks to
- Adrian Bunk for the patches).
- - Integrated NetBSD/OpenBSD patches from Marc Recht and Matthias Drochner.
-
-Since 6.3alpha6:
- - Compile test_cpp.cc with CXXCOMPILE instead of COMPILE.
- - Very large allocations could cause a collector hang. Correct
- calculation of GC_collect_at_heapsize.
- - GC_print_hblkfreelist printed some bogus results if USE_MUNMAP
- was defined.
- - Include gc_config_macros.h in threadlibs.c.
- - Correct MacOSX thread stop code. (Thanks to Dick Porter.)
- - SMALL_OBJ definition was off by one. This could cause crashes
- at startup. (Thanks to Zoltan Varga for narrowing this down to
- a trivial test case.)
- - Integrate Paolo Molara's patch to deal with a race in the Darwin
- thread stopping code.
- - Changed X86_64 implementation to use SA_SIGINFO in the MPROTECT_VDB
- implementation. The old approach appears to have been broken by
- recent kernels.
- - Added GC_ATTR_UNUSED to eliminate a warning in gc_allocator.h (Thanks
- to Andrew Begel.)
- - Fix GC_task_self declaration in os_dep.c. (Thanks to Andrew Pinski.)
- - Increase INITIAL_BUF_SZ in os_dep.c for Solaris /proc reads.
-
-Since gc6.3:
- - Merge gcconfig.h changes from gcc tree.
- - Unconditionally include gc_priv.h in solaris_pthreads.c, win32_threads.h,
- aix_irix_threads.c, and solaris_threads.c to get thread definitions.
- - Start marker threads in GC_thr_init, so that they get started even
- if no other threads are ever started. (Oddly enough, the parallel
- collector worked correctly, though not well, with no helper threads.)
- - Go ahead and split large blocks in GC_allochblk_nth if GC_dont_gc
- is set. (Thanks to Alexander Petrossian.)
- - GC_PRINT_BACK_HEIGHT would deadlock with thread support.
- - Let in_progress_space in backgraph.s grow dynamically.
- - Fix README.solaris2. The GC_thr_init() hack doesn't work anymore.
- - Convert GC_finalizer_mem_freed to bytes in allchblk.c.
- - Add missing declaration for GC_generic_malloc_words_small_inner.
- Without it, s390x breaks. (Thanks to Ulrich Weigand.)
- - Applied several MacOSX patches to support older tool chains.
- (Thanks to Stefan Ring.)
- - Bug fix for NetBSD/amd64. (Thanks to Marc Recht.) Add NetBSD/sh3
- support. (Thanks to Uchiyama Yasushi.)
- - Fixed an uninitialized variable in cordprnt.c. (Thanks to gcc for
- providing the warning.)
- - Eliminated some, but not all, gcc -Wall warnings.
- - Changed some old style casts to reinterpret_cast in new_gc_alloc.h.
- (Thanks to Dan Grayson.)
- - GC_extend_size_map shouldn't adjust for GC_all_interior_pointers if
- GC_DONT_ADD_BYTE_AT_END is set.
- - Changed some (long) casts to (word) in preparation for win64.
- (Thanks to Peter Colson.)
- - Changed "int stack_size" declaration in pthread_support.c to use
- size_t. (Only mattered with GC_ASSERTIONS enabled.)
- - Added CRIS (etrax) support. (Thanks to Simon Posnjak and
- Hans-Peter Nilsson.)
- - Removed GC_IGNORE_FB frame buffer recognition, and replaced
- it with a check that the mapping type is MEM_IMAGE.
- In theory, this should work much better, but it is a high
- risk change for win32. (Thanks to Ashley Bone for the crucial
- experimental data behind this, and to Rutger Ovidus for
- some further experiments.)
- - GC_allochblk_nth incremented GC_words_wasted by bytes rather than
- words.
- - Consider GC_words_wasted in GC_adj_words_allocd only if it is within
- reason. (A hack to avoid some extremely unlikely scenarios in which
- we manage to allocate only "wasted" space. 7.0 has a better fix.)
- - Changed PowerPC GC_clear implementation to use lwsync instead of
- eieio, since the documentation recommends against eieio, and
- it seems to be incorrect if the preceding memory op is a load.
- - Fixed print_block_list to print the correct kind number for
- STUBBORN. (Thanks to Rutger Ovidus.)
- - Have configure.in generate an error if it is asked to support
- pthreads, but doesn't know how to.
- - Added Kazuhiro Inaoka's patch for Renesas M32R support.
- - Have the GNU build mechanism link with -ldl. Rename THREADLIBS
- to THREADDLLIBS to reflect this. (Thanks to Sven Verdoolaege.)
- - Added Hannes Mehnert's patch for FreeBSD/SPARC support.
- - Merged some FreeBSD specific patches to threadlibs.c and dyn_load.c.
- (Thanks tp John Merryweather Cooper.)
- - Define MPROTECT_VDB on MACOSX only if threads are being used, since the
- dirty page tracking mechanism uses threads. (This avoids an undefined
- reference to _GC_darwin_register_mach_handler_thread.)
- - By popular demand, use __libc symbols only if we are built with
- USE_LIBC_PRIVATES, which is off by default, and not otherwise documented.
- - Ignore GC_enable_incremental() requests when KEEP_BACK_PTRS is set.
- The GC itself will dirty lots of pages in this cases, probably making
- it counterproductive on all platforms. And the DARWIN port crashes.
-
-Since gc6.4:
- - Integrated Paolo Molaro's patch to deal with EINTR in sem_wait.
- - Make GC_approx_sp() write to dummy location to ensure that stack
- is grown here, when sp looks reasonable, rather than later, when
- it might look like a bad memory reference. (Problem was never
- observed that I know of. But on rereading the code it seemed
- dubious.)
- - Separate out GC_with_callee_saves_pushed and sometimes call
- it from GC_suspend_handler in pthread_stop_world.c. Callee-save
- register values sometimes failed to get traced under HP/UX on
- PA-RISC. Linux/IA64 had the same problem, though non-stacked
- callee-save registers seem to be so rarely used there that nobody
- ever noticed.
- - Integrated an ancient Darwin powerpc_darwin_machine_dep.s patch
- from Andreas Tobler, which I had lost.
- - Fix compare_and_exchange implementation for gcc/IA64 to deal with
- pickier compiler versions.
- - Fixed Itanium 32-bit ABI support (HP/UX). In particular, the
- compare_and_exchange implementation didn't consider that possibility.
- - Undefine GC_pthread_detach in win32_threads.c. (Thanks to
- Tagliapietra Tommaso.)
- - Fixed inclusion of frame.h for NETBSD in os_dep.c.
- - Applied Dan Bonachea's patch to use mmap on AIX.
- - Several fixes to resurrect the Irix port on recent OS versions.
- - Change ALPHA to use LINUX_STACKBOTTOM.
- - Change SPARC64/LINUX to also use LINUX_STACKBOTTOM. Deal with potential
- bad values of __libc_stack_end on that platform. (Thanks to David Miller.)
- - Relax gctest to allow larger heap if ALIGN_DOUBLE isn't set.
- (Unnecessary in 7.0)
- - Force a define of __STDC__=0 for the IBM compiler on AIX, so that
- we get prototypes. (Unnecessary in 7.0)
- - GC_INIT definition for AIX and CYGWIN referred to DATASTART and DATAEND
- which are only defined in private include files.
- - Integrated some small gcconfig.h patches from Dan Bonachea. Also
- relaxed assertion about FreeBSD stack size in pthread_support.c.
- - Integrated Andrew Begel's darwin_stop_world.c patch for 64-bit
- support. This may need additional work.
- - Avoided potentially infinite recursion in GC_save_callers if
- the system backtrace calls malloc. The workaround currently requires
- __thread support if this code is used with threads.
- - Avoided another similar infinite recursion by conditionally
- invoking GC_save_callers in alloc.c. (Thanks to Matthias Andree
- for helping to track down both of these.)
- - Removed all traces of aix_irix_threads.c. AIX and Irix now use
- pthread_support.c and pthread_stop_world.c. The old code appeared
- to be unreliable for AIX, and was not regularly maintained.
- - On Irix, ignore segments with MA_FETCHOP or MA_NOTCACHED attributed;
- they're not always safe to read.
- - Fixed a previously vacuous assertion (diagnosed by the SGI compiler)
- in GC_remove_from_fl.
- - Fix stack_size assertion in GC_pthread_create.
- - Fix assertion in GC_steal_mark_stack.
-
-Since gc6.5:
- - Fix CPU count detection for Irix and FreeBSD. (Thanks to Dan Bonachea.)
- - Integrate Dan Bonachea's patch for the IBM XLC compiler on Darwin.
- - Integrated Andreas Tobler's FreeBSD/PowerPC patch.
- - Don't access the GC thread structure from the restart handler. It's
- unsafe, since the handler may run too late. (Thanks to Ben Maurer for
- tracking this down.)
- - Applied Christian Thalinger's patch to change comment syntax in
- alpha_mach_dep.S.
- - Added test for GC_no_dls in GC_dyld_image_add for DARWIN. (Thanks to
- Juan Jose Garcia Ripoli).
- - Use LINUX_STACKBOTTOM for Linux/SH and LINUX/ARM. (Thanks to Sugioka
- Toshinobu and Christian Thalinger.)
- - Rewrote GC_parse_map_entry. This assumed a fixed column layout of
- /proc/self/maps on Linux. This ceased to be true about 2 years ago.
- The old code is probably quite problemetic with -DREDIRECT_MALLOC. It
- is also used by default for IA64, though I haven't seen actual failures
- there.
- - More consistently define HBLKSIZE to 4096 on 64 bit architectures with
- 4K pages. (Thanks to Andrew Haley.)
- - With win32 threads, GC_stop_world needs to acquire GC_write_cs. (Thanks
- to Ben Hutchings for the observation and patch.)
- - Move up struct callinfo declaration to make gcc 4.0.2. happy.
-
-Since 6.6:
- - Add "int" to Solaris "end" and "etext" declaration in gc.h. Declared
- the symbols with underscores and as arrays, since that's what's actually
- used. Perhaps this could all just be removed? (Thanks to John Bowman.)
- - Fixed ARM GC_test_and_set code. (Thanks to Kazu Hirata and Paul Brook.)
- - Added casts for assignments to hb_last_reclaimed, which truncate the
- value. Added a cast to GC_adj_words_allocd. Use GetModuleHandleA
- when retrieving a handle to kernel32.dll under win32. (Thanks to the
- Visual Prolog developers.)
- - Added Tandem S-Series support. (Thanks to Craig McDaniel. A modified
- version of his patch was applied, and hence breakage is probably not
- his fault.)
- - Remove spurious gc:: qualifier for operator delete[] in gc_cpp.h.
- (Thanks to Hanno Boeck.)
- - Changed a test for LINUX in config_macros.h to one for __linux__.
- - Add prototypes for GC_finalizer_notifier and GC_thr_init. (Thanks to
- David Ayers.)
- - Use ld instead of nonexitent ldz instruction in Darwin FindTopOfStack.
- (Thanks to Andreas Tobler.)
- - Add support for Darwin/X86. (Thanks to Geoff Norton and the Mono
- developers.)
- - Merge in some recent gcc fixes. Add ppc64 asm code. (Thanks to Bryce
- McKinley and other gcj developers.)
- - Scan MEM_PRIVATE sections under Windows ME and predecessors.
- - Interior pointers with some largish offsets into large objects could
- be ignored, if GC_all_interior_pointers was set. (Oddly this worked
- correctly for stack references if it was not set. Otherwise it failed
- for both stack and heap references.) Thanks to Andrew McKinlay for the
- critical test case.
- - Integrated Tatsuya Bizenn's NETBSD threads support, with some
- untested changes.
- - Added GC_strdup and friends to make leak detection work correctly
- for strdup clients. (Thanks to Jon Moore.) Fixed the existing strdup
- with malloc redirection to handle a null malloc return correctly.
-
-Since gc6.7:
- - Added some support for Dragonfly BSD. (Thanks to Joerg Sonnenberger and
- Thomas Klausner.)
- - Improvements to the HP/UX section of configure.in/configure.ac.
- (Thanks to Andreas Tobler)
- - GC_unix_get_mem could neglect to release the malloc lock on Irix, under
- extremely unlikely circumstances. Thanks to Jean-Baptiste Nivois for
- some careful code reading.
- - Added support for kFreeBSD + glibc (Thanks to Petr Salinger)
- - Fix more MacOS threads memory leaks (Thanks to Allan Hsu)
- - Added initial Solaris/X86-64 support (Thanks to Rainer Orth)
-
-Since gc6.8:
- - Fix typo in PREFETCH implementation for X86_64. (Thanks to Peter Wang.)
- - Fix M68K LINUX port. (Thanks to Debian packagers.)
- - __GNUC__ was misspelled as __GNUC in new_gc_alloc.h. (Thanks to Peter Wang.)
- - Integrated Allan Hsu's patch for OS X VM deallocation problems.
- - Applied FreeBSD/X86_64 patch.
-
-Since gc6.9:
- - Remove GC_PROTO, VOLATILE, GC_PTR, and GC_CONST. Assume ANSI C compiler
- and use ANSI constructs unconditionally.
- - Introduce #elif and #error in some of the appropriate places.
- - Remove GC_printf cruft. Use stdargs.
- - Remove separate Solaris threads support. Use the more generic Posix
- implementation.
- - Use atomic_ops for atomic operations and memory barriers.
- - Clean up MPROTECT_VDB implementation. Use SA_SIGINFO wherever
- possible.
- - Remove broken SIGNALS stuff.
- - Use size_t instead of word, where appropriate.
- - Add .S.o rule to Makefile.am.
- - Officially unsupport SunOS4, several old flavors of M68K (SunOS4,
- A/UX, HP), IBM PC/RTs and RISCOS/Irix4. (I doubt the old code worked.
- If anyone cares, these should be easy to resurrect.)
- - Add EXPECT() in some critical places.
- - Redefined hb_sz and hb_body to deal with bytes rather than words.
- This affected a great deal of code. I would like to consistently use
- byte offsets and sizes where there's not a convincing reason to do
- otherwise.
- - Redefined several other variables (GC_mem_found, GC_words_allocd)
- etc. to use units of bytes. Most of these were also renamed to
- reflect that fact.
- - Killed as many "register" declarations as possible.
- - Partially replaced stubborn allocation with manual write barrier.
- It's currently broken.
- - Restructured mark code, to allow mark bits to be kept either on
- a per allocation granule or per object basis. The emphasis is
- now on the -DUSE_MARK_BYTES option, since individual bits perform
- quite badly on hyperthreaded P4s, and are probably suboptimal on
- other architectures. -DUSE_MARK_BITS is currently broken, and may
- be resurrected only for the single-threaded case. This significantly
- reduced the cache footprint required by auxiliary GC data structures.
- It also reduces space overhead for small heaps. It probably slows
- things down slightly if interior pointers are very common.
- - As part of the above, we now maintain an approximate count of set
- mark bits in each heap block.
- - As part of the above, the semantics of hb_map changed drastically.
- For MARK_BIT_PER_OBJ, it doesn't exist. For MARK_BIT_PER_GRANULE,
- it is purely a way to replace a mod instruction with a table lookup.
- (Somewhat to my surprise, this still wins on modern hardware.)
- - Removed PRINTSTATS, GATHERSTATS, and SILENT macros. Everything is
- now controlled by GC_print_stats variable and GC_PRINT_STATS
- and new GC_PRINT_VERBOSE_STATS environment variables.
- - Add GC_log_printf and use it consistently for logging output.
- - Unconditionally count the objects we reclaim in the sweep phase.
- For thread local allocation, we need that anyway, and we expect
- that's increasingly the only case that matters. And it simplifies
- the code. In general expect minor performance hacks that benefit
- only the single-threaded case to disappear.
- - Remove GC_quiet from gc.h and elsewhere.
- - Changed the heap expansion heuristic, and the definition of
- GC_free_space_divisor, to refer to live data size, instead of total
- heap size. I believe this is much more robust. It wasn't previously
- possible, because we didn't have access to live data size.
- - Thread local allocation added the extra byte in twice: Once in
- thread_local_alloc, and once in malloc_many.
- - Removed GC_malloc_words_small and GC_gcj_fast_malloc. A new
- mechanism based on the thread local allocation data structures
- is expected to be added instead. This should allow inlined code
- that is both fast and doesn't rely on collector internals.
- - Changed both free lists and reclaim lists to be indexed by granules
- instead of words, norming halving their size.
- - MERGE_SIZE is now the only option, and the macro was removed.
- (Without it, we need a memory reference to GC_all_interior_pointers
- anyway. Thus it costs us nothing.)
- - Change GC_size_map to map to granules instead of words. Make sure
- that every possible size up to TINY_FREELISTS is present.
- - Split of macros need for fast inline allocation into gc_tiny_fl.h
- in anticipation of a new inline allocator that doesn't rely on GC
- internals.
- - Changed thread local allocation to use GRANULE_BYTES and TINY_FREELISTS
- in anticipation of a merge with the inline allocation code.
- - Removed ALIGN_DOUBLE. This is mostly handled by GRANULE_BYTES.
- - Make locking on most platforms conditional on GC_need_to_lock.
-
-Since gc7.0alpha1:
- - GC_bytes_allocd was incremented by a possibly uninitialized variable
- in GC_generic_malloc_inner. (Bug introduced in gc7.0alpha1. Thanks
- to Ben Hutchings for tracking it down.)
- - Win32 fixes. (Thanks to Ben Hutchings and Maurizio Vairani.)
- - Integrated Ben Hutchings' GetWriteWatch-based virtual dirty bit
- implementation for win32.
- - Removed pc_gc.tar and floppy targets in Makefile.direct. Removed
- pc_excludes file.
- - No longer include GC_bytes_wasted when evaluating allocation progress.
- Since we are now counting live memory, it no longer makes sense.
- - Applied Davide Angelocola's configury patch. There are now separate
- Makefile.am's in the cord and tests subdirectory, more tests, etc.
- - Renamed configure.in to configure.ac.
- - Merged a very small number of Nathanael Nerode's configure.ac
- cleanups from the gcc tree. Unfortunately, that file is a bit
- different from ours.
- - Changed EINTR handling in sem_wait slightly.
- - Restructure the root marking code. Remove all traces of
- USE_GENERIC_PUSH_REGS, and effectively make it the default.
- Make it easier to pass a context pointer to the mark routine, in
- case we ever want to do precise stack marking.
- - Replace GC_start_blocking() and GC_end_blocking() with GC_do_blocking().
- This remains undocumented, and only implemented for pthreads. But it
- removes an otherwise unavoidable race with stores of callee-save
- registers.
- - Fix GC_n_mark_bits for the default MARK_BIT_PER_GRANULE case. This
- resulted in bogus complaints in heap dumps.
- - Upgrade to libatomic_ops-1.0, and update build structure to match.
- - Remove SRC_M3 support. Clean up lock initialization code in misc.c.
- - Removed gc_local_alloc.h. If THREAD_LOCAL_ALLOC is defined, the
- thread local allocation routines are now called automatically.
- - Renamed gc_inl.h back to gc_inline.h. Changed the interface appreciably
- since locking has turned into a dominant issue, and in-line allocation
- only makes sense if it's no worse than thread-local allocation.
- Gc_inline.h is now also used to implement thread-local allocation.
- - Finished replacing stubborn allocation with manual write barrier.
- Untested.
- - Use thread-local allocation code by default.
- - Added GC_register_my_thread and friends for Posix and win32.
- - Patch for GWW_VDB from Ben Hutchings.
- - Removed explicit THREAD_LOCAL_ALLOC tests, since that now always
- redefines GC_malloc.
- - Removed now unused AIX memory allocation code.
- - Various minor fixes for bugs introduced in 7.0alpha1.
-
-Since gc7.0alpha2:
- - Added support for dlopen-based interception of pthread functions.
- This is only half done. The gc.h redefinitions currently interfere.
- - Integrated major automake overhaul from Petter Urkedal.
-
-Since gc7.0alpha3:
- (various 6.5, 6.6 changes)
- - Removed GC_brief_async_signal_safe_sleep and used atomic_ops instead.
- (Thanks to Ben Maurer.)
- - Integrated build patches from David Angelocola and Petter Urkedal.
- - Fix dynamic-linker-based pthread call redirection.
- - Renamed RS6000 to POWERPC/AIX.
- - Allow recovery from SIGSEGV in marker on Linux. This works around
- a race in thread stack marking if /proc is used to find roots. We do
- that by default with malloc redirection and threads. This involved
- moving some GC_find_limit and SETJMP related declarations to gc_priv.h.
- - Added doc/porting.html file.
- - Added ADD_HEAP_GUARD_PAGES for sbrk/*nix platforms to debug extreme
- memory overwrite errors.
- - Added trivial NO_INCREMENTAL flag to facilitate debugging.
- - Added GC_getattr_np-based GC_get_stack_base (untested).
- - Separated thread local allocation into a separate file and added the
- beginning of win32 support for that.
-
-Since gc7.0alpha4:
- (more 6.6, 6.7 changes)
- - Some Solaris fixes, including some more general changes in how
- the assembly pieces of mach_dep.c are handled.
- - Removed a lot of SOLARIS_THREADS-specific code that was only
- needed with the old implementation. This included many (mostly no-op)
- versions of GC_is_fresh.
- - Don't use atomic_ops in gc_locks.h unless we need threads.
- - Fixed USE_MARK_BITS, which is once againthe default without PARALLEL_MARK.
- - Removed Solaris GC_INIT hack. It's a workaround for a long dead bug,
- and it seemed to be wrong anyway.
- - Changed win32_threads.c to require preprocessor-based interception
- of thread routines by default. A client call to GC_use_DllMain is
- now required to get the old behavior in which DllMain is used to implicitly
- register threads. This was doen for uniformity with other platforms, and
- because the DllMain solution seemed to require very tricky code which,
- at least in the past, imposed hard bounds onthe number of threads.
- - Many small changes to make thread support work again on Cygwin.
- - Moved definition of allocator lock etc. to pthread_support.c and
- win32_threads.c for those two cases.
- - Got rid of the FASTLOCK() machinery. It doesn't seem useful on modern
- platforms.
- - Cleaned up the uncollectable allocation routines, speeding up the
- slower paths. The code did enough unnecessary work off the critical path
- that the underlying logic was getting hard to extract.
- - No longer turn off THREAD_LOCAL_ALLOC with DBG_HDRS_ALL. Indications
- are it just works, and I think the reasons for it not working disappeared
- a while ago.
- - Fixed bugs in hb_n_marks calculation and assertion.
- - Don't use __builtin_expect for pre-3.0 gcc.
- - Define GWW_VDB only for recent Microsoft tool chains.
- - Add overview.html to doc directory.
- - Fix NT_STATIC_THREADS_MAKEFILE, various compiler warnings.
- - Made thread local allocation sort of work with Cygwin. The code should
- be there to deal with other Windows variants, But non-Cygwin Windows
- threads need more bug fixes.
-
-Since gc7.0alpha5:
- (more 6.7 changes)
- - Declare GC_dump() in gc.h.
- - Add --enable-large-config, which just defines the LARGE_CONFIG macro.
- - Make GlobalAlloc address alignment a bit more intuitive. (Thanks to
- Charles Mills.)
- - Use #elif in the definitions of GET_MEM.
- - Overhaul porting.html. Remove corresponding text from README.
- - Fix typo in DARWIN section of gcconfig.h.
- - Fix Darwin thread memory leak. (Thanks to Bruce Mitchener.)
- - Update x86 AO_test_and_set implementation to use "=q".
- - Add $(EXEEXT) to many tests in tests/tests.am. (Corresponds to a
- 6.7 fix, which no longer applied.)
- - Fix Darwin/PPC port.
- - Fix Cygwin/threads port.
- - Fix gcj malloc support.
- - For GNU-style make, don't build libatomic_ops unless threads are requested.
- This should allow single-threaded builds on platforms which do not
- currently support libatomic_ops.
- - Clean up and hopefully fix the CFLAGS calculation for GNU build.
- (Substantially improves things on HP/UX.)
- - Integrated Andrei Polushin's Visual C++ patches. These provide for
- stack traces, better C++ debug support, and better log file handling.
- Note that these change the location of the log file to a the path of the
- executable with a .log extension. To get the old behavior back, define
- OLD_WIN32_LOG_FILE. For the time being, I'm checking his project
- files and the like into a windows-untested subdirectory. They
- are almost certainly already out of date, but better than what we had
- before.
- - Fixed some win32 threads bugs, and added support for _beginthreadex.
- - Fix zero size thread local allocation so that explicit deallocation
- works correctly.
- - Removed serious bug in GC_malloc_uncollectable(large size).
- - Do not try to do thread-local gcj allocation in incremental mode. There
- are races in setting up the descriptor.
- - Add GC_INIT() to middle.c, fix some more GC_printfn calls.
- - Some assertions erroneously used I_HOLD_LOCK() negatively, eventhough
- it can now spuriously return TRUE.
- - Rename SUNOS5 macro and OS name to SOLARIS and SUNOS5DL to SOLARISDL.
- - On Linux and some Un*x variants, allocate memory by first trying sbrk,
- and then switching to mmap if that fails.
- - Fixed /proc/x/maps reading to deal with asynchronous deletions.
- - Fix REDIRECT_MALLOC with threads on Linux. It now usually seems to work
- with ugly hacks that include having calloc behave differently when it is
- called from ld.so or the pthreads library. A reasonable amount of
- infrastructure was added to support some of this. Thanks to Roland McGrath
- for ideas and information.
- - Import various updated build scripts.
- - Add GC_register_has_static_roots_callback. (Thanks to Andrew Haley.)
- - Fix serious bugs in GC_malloc_atomic_uncollectable().
- - Return GC_SUCCESS form GC_get_stack_base().
- - Fix several atomic_ops problems on IA64 with HP Compiler.
- - Update to atomic_ops-1.2.
- - Fix hb_n_marks description and reclaim.c assertion.
- - Various additional win32 threads fixes.
- - Enable GC_ASSERTIONS for Debug build with NT_THREADS_MAKEFILE.
-
-[gc7.0alpha7 was released and version bumped to gc7.0alpha8]
-
-Since first gc7.0alpha8 version:
- [ Some gc6.9 changes ]
- - Change FindTopOfStack decl in darwin_stop_world.c.
- - Move some static tests from misc.c to gcconfig.h. Use #error.
- - Add GC_print_free_list() function. (Thanks to Bruce Hoult.)
- - Add GC_GNU_THREADS support on HURD. (Thanks to Aleksey Demakov,
- Barry DeFreese, and possibly other Debian maintainers.)
- - __GNUC__ was misspelled as __GNUC in thread_local_alloc.h.
- (Thanks to Peter Wang.)
- - Integrated various MacOSX patches and tried to reconcile them.
- Thanks to Allan Hsu, several contributers at Apple, and probably
- others.
- - Added some casts to powerpc.h in libatomic_ops to silence warnings.
-
-To do (OLD):
- - REDIRECT_MALLOC and threads combination should work on more platforms,
- and needs more testing on Linux.
- - Clone marker inner loop to support arch-dependent prefetching,
- and counting of objects marked for finalization.
- - The USE_MUNMAP code should really use a separate data structure
- indexed by physical page to keep track of time since last use of
- a page. Using hblk headers means we lose track of ages when
- blocks are merged, and we can't unmap pages that have been allocated and
- dropped by the blacklisting code. I suspect both of these matter.
- - A dynamic libgc.so references dlopen unconditionally, but doesn't link
- against libdl.
- - GC_proc_fd for Solaris is not correctly updated in response to a
- fork() call. Thus incremental collection in the child won't work
- correctly. (Thanks to Ben Cottrell for pointing this out.)
- - --enable-redirect-malloc is mostly untested and known not to work
- on some platforms.
- - There seem to be outstanding issues on Solaris/X86, possibly with
- finding the data segment starting address. Information/patches would
- be appreciated.
- - Very large root set sizes (> 16 MB or so) could cause the collector
- to abort with an unexpected mark stack overflow. (Thanks again to
- Peter Chubb.) NOT YET FIXED. Workaround is to increase the initial
- size.
- - The SGI version of the collector marks from mmapped pages, even
- if they are not part of dynamic library static data areas. This
- causes performance problems with some SGI libraries that use mmap
- as a bitmap allocator. NOT YET FIXED. It may be possible to turn
- off DYNAMIC_LOADING in the collector as a workaround. It may also
- be possible to conditionally intercept mmap and use GC_exclude_static_roots.
- The real fix is to walk rld data structures, which looks possible.
- - Incremental collector should handle large objects better. Currently,
- it looks like the whole object is treated as dirty if any part of it
- is.
+* Fixed spurious
+assembly language assignments to TMP_SP. Only the assignment in the PC/RT
+code is necessary. On other machines, with certain compiler options,
+the assignments can lead to an unsaved register being overwritten.
+Known to cause problems under SunOS 3.5 WITHOUT the -O option. (With
+-O the compiler recognizes it as dead code. It probably shouldn't,
+but t2hat's another story.)
