- 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.)
+
+Since gc6.6:
- 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.
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 Angeloca's configury patch. There are now separate
- Makefile.am's in the cord and tests supdirectory, more tests, etc.
+ - 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
- 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.
To do:
- Fix USE_MARK_BITS.
+ - REDIRECT_MALLOC and threads combination is getting closer, but currently
+ usually fails because the DTV (dynamic thread vector) used to access
+ thread-local storage is referenced only from the base of a thread stack,
+ but often allocated through malloc. The symptom on IA64 is a runaway
+ memset in thread creation, which may cause failures elsewhere.
+ Typically large heap sections end up cleared.
- Clone marker inner loop to support arch-dependent prefetching,
and counting of objects marked for finalization.

+The C++ interface is implemented as a thin layer on the C interface.
+Unfortunately, this thin layer appears to be very sensitive to variations

+Your platform may need minor adjustments in this layer (gc_cpp.cc, gc_cpp.h,

+But it's easy to break one platform by fixing another.)

+Usage of the collector from C++ is also complicated by the fact that there

+<BODY>
+<H1>Conservative GC Porting Directions</h1>
+The collector is designed to be relatively easy to port, but is not
+portable code per se. The collector inherently has to perform operations,
+such as scanning the stack(s), that are not possible in portable C code.
+<P>
+All of the following assumes that the collector is being ported to a
+byte-addressable 32- or 64-bit machine. Currently all successful ports
+to 64-bit machines involve LP64 targets. The code base includes some
+provisions for P64 targets (notably win64), but that has not been tested.
+You are hereby discouraged from attempting a port to non-byte-addressable,
+or 8-bit, or 16-bit machines.
+<P>
+The difficulty of porting the collector varies greatly depending on the needed
+functionality. In the simplest case, only some small additions are needed
+for the <TT>include/private/gcconfig.h</tt> file. This is described in the
+following section. Later sections discuss some of the optional features,
+which typically involve more porting effort.
+<P>
+Note that the collector makes heavy use of <TT>ifdef</tt>s. Unlike
+some other software projects, we have concluded repeatedly that this is preferable
+to system dependent files, with code duplicated between the files.
+However, to keep this manageable, we do strongly believe in indenting
+<TT>ifdef</tt>s correctly (for historical reasons usually without the leading
+sharp sign). (Separate source files are of course fine if they don't result in
+code duplication.)
+<H2>Adding Platforms to <TT>gcconfig.h</tt></h2>
+If neither thread support, nor tracing of dynamic library data is required,
+these are often the only changes you will need to make.
+<P>
+The <TT>gcconfig.h</tt> file consists of three sections:
+<OL>
+<LI> A section that defines GC-internal macros
+that identify the architecture (e.g. <TT>IA64</tt> or <TT>I386</tt>)
+and operating system (e.g. <TT>LINUX</tt> or <TT>MSWIN32</tt>).
+This is usually done by testing predefined macros. By defining
+our own macros instead of using the predefined ones directly, we can
+impose a bit more consistency, and somewhat isolate ourselves from
+compiler differences.
+<P>
+It is relatively straightforward to add a new entry here. But please try
+to be consistent with the existing code. In particular, 64-bit variants
+of 32-bit architectures general are <I>not</i> treated as a new architecture.
+Instead we explicitly test for 64-bit-ness in the few places in which it
+matters. (The notable exception here is <TT>I386</tt> and <TT>X86_64</tt>.
+This is partially historical, and partially justified by the fact that there
+are arguably more substantial architecture and ABI differences here than
+for RISC variants.)
+<P>
+on GNU-based systems, <TT>cpp -dM empty_source_file.c</tt> seems to generate
+a set of predefined macros. On some other systems, the "verbose"
+compiler option may do so, or the manual page may list them.
+<LI>
+A section that defines a small number of platform-specific macros, which are
+then used directly by the collector. For simple ports, this is where most of
+the effort is required. We describe the macros below.
+<P>
+This section contains a subsection for each architecture (enclosed in a
+suitable <TT>ifdef</tt>. Each subsection usually contains some
+architecture-dependent defines, followed by several sets of OS-dependent
+defines, again enclosed in <TT>ifdef</tt>s.
+<LI>
+A section that fills in defaults for some macros left undefined in the preceding
+section, and defines some other macros that rarely need adjustment for
+new platforms. You will typically not have to touch these.
+</ol>
+The following macros must be defined correctly for each architecture and operating
+system:
+<DL>
+<DT><TT>MACH_TYPE</tt>
+<DD>
+Defined to a string that represents the machine architecture. Usually
+just the macro name used to identify the architecture, but enclosed in quotes.
+<DT><TT>OS_TYPE</tt>
+<DD>
+Defined to a string that represents the operating system name. Usually
+just the macro name used to identify the operating system, but enclosed in quotes.
+<DT><TT>CPP_WORDSZ</tt>
+<DD>
+The word size in bits as a constant suitable for preprocessor tests,
+i.e. without casts or sizeof expressions. Currently always defined as
+either 64 or 32. For platforms supporting both 32- and 64-bit ABIs,
+this should be conditionally defined depending on the current ABI.
+There is a default of 32.
+<DT><TT>ALIGNMENT</tt>
+<DD>
+Defined to be the largest <TT>N</tt>, such that
+all pointer are guaranteed to be aligned on <TT>N</tt>-byte boundaries.
+defining it to be 1 will always work, but perform poorly.
+For all modern 32-bit platforms, this is 4. For all modern 64-bit
+platforms, this is 8. Whether or not X86 qualifies as a modern
+architecture here is compiler- and OS-dependent.
+<DT><TT>DATASTART</tt>
+<DD>
+The beginning of the main data segment. The collector will trace all
+memory between <TT>DATASTART</tt> and <TT>DATAEND</tt> for root pointers.
+On some platforms,this can be defined to a constant address,
+though experience has shown that to be risky. Ideally the linker will
+define a symbol (e.g. <TT>_data</tt> whose address is the beginning
+of the data segment. Sometimes the value can be computed using
+the <TT>GC_SysVGetDataStart</tt> function. Not used if either
+the next macro is defined, or if dynamic loading is supported, and the
+dynamic loading support defines a function
+<TT>GC_register_main_static_data()</tt> which returns false.
+<DT><TT>SEARCH_FOR_DATA_START</tt>
+<DD>
+If this is defined <TT>DATASTART</tt> will be defined to a dynamically
+computed value which is obtained by starting with the address of
+<TT>_end</tt> and walking backwards until non-addressable memory is found.
+This often works on Posix-like platforms. It makes it harder to debug
+client programs, since startup involves generating and catching a
+segmentation fault, which tends to confuse users.
+<DT><TT>DATAEND</tt>
+<DD>
+Set to the end of the main data segment. Defaults to <TT>end</tt>,
+where that is declared as an array. This works in some cases, since
+the linker introduces a suitable symbol.
+<DT><TT>DATASTART2, DATAEND2</tt>
+<DD>
+Some platforms have two discontiguous main data segments, e.g.
+for initialized and uninitialized data. If so, these two macros
+should be defined to the limits of the second main data segment.
+<DT><TT>STACK_GROWS_UP</tt>
+<DD>
+Should be defined if the stack (or thread stacks) grow towards higher
+addresses. (This appears to be true only on PA-RISC. If your architecture
+has more than one stack per thread, and is not already supported, you will
+need to do more work. Grep for "IA64" in the source for an example.)
+<DT><TT>STACKBOTTOM</tt>
+<DD>
+Defined to be the cool end of the stack, which is usually the
+highest address in the stack. It must bound the region of the
+stack that contains pointers into the GC heap. With thread support,
+this must be the cold end of the main stack, which typically
+cannot be found in the same way as the other thread stacks.
+If this is not defined and none of the following three macros
+is defined, client code must explicitly set
+<TT>GC_stackbottom</tt> to an appropriate value before calling
+<TT>GC_INIT()</tt> or any other <TT>GC_</tt> routine.
+<DT><TT>LINUX_STACKBOTTOM</tt>
+<DD>
+May be defined instead of <TT>STACKBOTTOM</tt>.
+If defined, then the cold end of the stack will be determined
+Currently we usually read it from /proc.
+<DT><TT>HEURISTIC1</tt>
+<DD>
+May be defined instead of <TT>STACKBOTTOM</tt>.
+<TT>STACK_GRAN</tt> should generally also be undefined and defined.
+The cold end of the stack is determined by taking an address inside
+<TT>GC_init's frame</tt>, and rounding it up to
+the next multiple of <TT>STACK_GRAN</tt>. This works well if the stack base is
+always aligned to a large power of two.
+(<TT>STACK_GRAN</tt> is predefined to 0x1000000, which is
+rarely optimal.)
+<DT><TT>HEURISTIC2</tt>
+<DD>
+May be defined instead of <TT>STACKBOTTOM</tt>.
+The cold end of the stack is determined by taking an address inside
+GC_init's frame, incrementing it repeatedly
+in small steps (decrement if <TT>STACK_GROWS_UP</tt>), and reading the value
+at each location. We remember the value when the first
+Segmentation violation or Bus error is signalled, round that
+to the nearest plausible page boundary, and use that as the
+stack base.
+<DT><TT>DYNAMIC_LOADING</tt>
+<DD>
+Should be defined if <TT>dyn_load.c</tt> has been updated for this
+platform and tracing of dynamic library roots is supported.
+<DT><TT>MPROTECT_VDB, PROC_VDB</tt>
+<DD>
+May be defined if the corresponding "virtual dirty bit"
+implementation in os_dep.c is usable on this platform. This
+allows incremental/generational garbage collection.
+<TT>MPROTECT_VDB</tt> identifies modified pages by
+write protecting the heap and catching faults.
+<TT>PROC_VDB</tt> uses the /proc primitives to read dirty bits.
+<DT><TT>PREFETCH, PREFETCH_FOR_WRITE</tt>
+<DD>
+The collector uses <TT>PREFETCH</tt>(<I>x</i>) to preload the cache
+with *<I>x</i>.
+This defaults to a no-op.
+<DT><TT>CLEAR_DOUBLE</tt>
+<DD>
+If <TT>CLEAR_DOUBLE</tt> is defined, then
+<TT>CLEAR_DOUBLE</tt>(x) is used as a fast way to
+clear the two words at GC_malloc-aligned address x. By default,
+word stores of 0 are used instead.
+<DT><TT>HEAP_START</tt>
+<DD>
+<TT>HEAP_START</tt> may be defined as the initial address hint for mmap-based
+allocation.
+<DT><TT>ALIGN_DOUBLE</tt>
+<DD>
+Should be defined if the architecture requires double-word alignment
+of <TT>GC_malloc</tt>ed memory, e.g. 8-byte alignment with a
+32-bit ABI. Most modern machines are likely to require this.
+This is no longer needed for GC7 and later.
+</dl>
+<H2>Thread support</h2>
+Supporting threads requires that the collector be able to find and suspend
+all threads potentially accessing the garbage-collected heap, and locate
+any state associated with each thread that must be traced.
+<P>
+The functionality needed for thread support is generally implemented
+in one or more files specific to the particular thread interface.
+For example, somewhat portable pthread support is implemented
+in <TT>pthread_support.c</tt> and <TT>pthread_stop_world.c</tt>.
+The essential functionality consists of
+<DL>
+<DT><TT>GC_stop_world()</tt>
+<DD>
+Stops all threads which may access the garbage collected heap, other
+than the caller.
+<DT><TT>GC_start_world()</tt>
+<DD>
+Restart other threads.
+<DT><TT>GC_push_all_stacks()</tt>
+<DD>
+Push the contents of all thread stacks (or at least of pointer-containing
+regions in the thread stacks) onto the mark stack.
+</dl>
+These very often require that the garbage collector maintain its
+own data structures to track active threads.
+<P>
+In addition, <TT>LOCK</tt> and <TT>UNLOCK</tt> must be implemented
+in <TT>gc_locks.h</tt>
+<P>
+The easiest case is probably a new pthreads platform
+on which threads can be stopped
+with signals. In this case, the changes involve:
+<OL>
+<LI>Introducing a suitable <TT>GC_xxx_THREADS</tt> macro, which should
+be automatically defined by <TT>gc_config_macros.h</tt> in the right cases.
+It should also result in a definition of <TT>GC_PTHREADS</tt>, as for the
+existing cases.
+<LI>For GC7+, ensuring that the <TT>atomic_ops</tt> package at least
+minimally supports the platform. For earlier versions define
+<TT>GC_test_and_set</tt> in <TT>gc_locks.h</tt>.
+<LI>Making any needed adjustments to <TT>pthread_stop_world.c</tt> and
+<TT>pthread_support.c</tt>. Ideally none should be needed. In fact,
+not all of this is as well standardized as one would like, and outright
+bugs requiring workarounds are common.
+</ol>
+Non-preemptive threads packages will probably require further work. Similarly
+thread-local allocation and parallel marking requires further work
+in <TT>pthread_support.c</tt>, and may require better <TT>atomic_ops</tt>
+support.
+<H2>Dynamic library support</h2>
+The function <TT>GC-register_dynamic_libraries</tt> in <TT>dyn_load.c</tt>
+must be defined to invoke <TT>GC_cond_add_roots</tt> on each data segment
+that should be traced for pointers. The implementation is highly
+platform specific.
+<P>
+Implementations that scan for writable data segments are error prone, particularly
+in the presence of threads. They frequently result in race conditions
+when threads exit and stacks disappear. They may also accidentally trace
+large regions of graphics memory, or mapped files. On at least
+one occasion they have been known to try to trace device memory that
+could not safely be read in the manner the GC wanted to read it.
+<P>
+It is usually safer to walk the dynamic linker data structure, especially
+if the linker exports an interface to do so. But beware of poorly documented
+locking behavior in this case.
+<H2>Incremental GC support</h2>
+If incremental/generational GC support is needed, one of the
+"virtual dirty bit" implementations in <TT>os_dep.c</tt> must be ported.
