+# depending on how configure is run. This is pretty annoying, since

+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,

+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.

(Thanks again to Jeff Sturm.)
- Use NPRGREG in solaris_threads.c, thus printing all registers if things
go wrong.
- - Added GC_MARKERS envronment variable to allow use of a single marker
+ - 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
- 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.
+
To do:
+ - --enable-redirect-malloc is mostly untested and known not to work
+ on some platforms.
+ - The win32 collector ends up tracing some (most?) objects allocated with
+ the system allocator, in spite if the fact that it tries not to.
+ This costs time and space, though it remains correct.
+ We need a way to identify memory regions used by the system malloc(),
+ or an alternate way to locate dll data areas. A very partial
+ workaround is to use GC_malloc_atomic_uncollectable() instead of
+ the system malloc() for most allocation.
- There seem to be outstanding issues on Solaris/X86, possibly with
finding the data segment starting address. Information/patches would
be appreciated.
- Incremental collector should handle large objects better. Currently,
it looks like the whole object is treated as dirty if any part of it
is.
- - Cord/cordprnt.c doesn't build on a few platforms (notably PowerPC), since
- we make some unwarranted assumptions about how varargs are handled. This
- currently makes the cord-aware versions of printf unusable on some platforms.
- Fixing this is unfortunately not trivial.
+
GC_INITIAL_HEAP_SIZE=<bytes> - Initial heap size in bytes. May speed up
process start-up.
+GC_MAXIMUM_HEAP_SIZE=<bytes> - Maximum collected heap size.
+
GC_LOOP_ON_ABORT - Causes the collector abort routine to enter a tight loop.
This may make it easier to debug, such a process, especially
for multithreaded platforms that don't produce usable core
by setting GC_quiet. On by default if the collector
was built without -DSILENT.
+GC_DUMP_REGULARLY - Generate a GC debugging dump GC_dump() on startup
+ and during every collection. Very verbose. Useful
+ if you have a bug to report, but please include only the
+ last complete dump.
+
GC_PRINT_ADDRESS_MAP - Linux only. Dump /proc/self/maps, i.e. various address
maps for the process, to stderr on every GC. Useful for
mapping root addresses to source for deciphering leak
since GC_MARKERS has no impact on the lock implementation.
GC_NO_BLACKLIST_WARNING - Prevents the collector from issuing
- "Needed to allocate blacklisted block at ..." warnings.
+ warnings about allocations of very large blocks.
+ Deprecated. Use GC_LARGE_ALLOC_WARN_INTERVAL instead.
+
+GC_LARGE_ALLOC_WARN_INTERVAL=<n> - Print every nth warning about very large
+ block allocations, starting with the nth one. Small values
+ of n are generally benign, in that a bounded number of
+ such warnings generally indicate at most a bounded leak.
+ For best results it should be set at 1 during testing.
+ Default is 5. Very large numbers effectively disable the
+ warning.
GC_IGNORE_GCJ_INFO - Ignore the type descriptors implicitly supplied by
GC_gcj_malloc and friends. This is useful for debugging
of Conservative Garbage Collectors", POPL 2001, or
http://lib.hpl.hp.com/techpubs/2001/HPL-2001-251.html .
+GC_RETRY_SIGNALS, GC_NO_RETRY_SIGNALS - Try to compensate for lost
+ thread suspend signals in linux_threads.c. On by
+ default for GC_OSF1_THREADS, off otherwise. Note
+ that this does not work around a possible loss of
+ thread restart signals. This seems to be necessary for

+<TITLE>Using the Garbage Collector as Leak Detector</title>
+</head>
+<BODY>
+<H1>Using the Garbage Collector as Leak Detector</h1>
+The garbage collector may be used as a leak detector.
+In this case, the primary function of the collector is to report
+objects that were allocated (typically with <TT>GC_MALLOC</tt>),
+not deallocated (normally with <TT>GC_FREE</tt>), but are
+no longer accessible. Since the object is no longer accessible,
+there in normally no way to deallocate the object at a later time;
+thus it can safely be assumed that the object has been "leaked".
+<P>
+This is substantially different from counting leak detectors,
+which simply verify that all allocated objects are eventually
+deallocated. A garbage-collector based leak detector can provide
+somewhat more precise information when an object was leaked.
+More importantly, it does not report objects that are never
+deallocated because they are part of "permanent" data structures.
+Thus it does not require all objects to be deallocated at process
+exit time, a potentially useless activity that often triggers
+large amounts of paging.
+<P>
+All non-ancient versions of the garbage collector provide
+leak detection support. Version 5.3 adds the following
+features:
+<OL>
+<LI> Leak detection mode can be initiated at run-time by
+setting GC_find_leak instead of building the collector with FIND_LEAK
+defined. This variable should be set to a nonzero value
+at program startup.
+<LI> Leaked objects should be reported and then correctly garbage collected.
+Prior versions either reported leaks or functioned as a garbage collector.
+</ol>
+For the rest of this description we will give instructions that work
+with any reasonable version of the collector.
+<P>
+To use the collector as a leak detector, follow the following steps:
+<OL>
+<LI> Build the collector with -DFIND_LEAK. Otherwise use default
+build options.
+<LI> Change the program so that all allocation and deallocation goes
+through the garbage collector.
+<LI> Arrange to call <TT>GC_gcollect</tt> at appropriate points to check
+for leaks.
+(For sufficiently long running programs, this will happen implicitly,
+but probably not with sufficient frequency.)
+</ol>
+The second step can usually be accomplished with the
+<TT>-DREDIRECT_MALLOC=GC_malloc</tt> option when the collector is built,
+or by defining <TT>malloc</tt>, <TT>calloc</tt>,
+<TT>realloc</tt> and <TT>free</tt>
+to call the corresponding garbage collector functions.
+But this, by itself, will not yield very informative diagnostics,
+since the collector does not keep track of information about
+how objects were allocated. The error reports will include
+only object addresses.
+<P>
+For more precise error reports, as much of the program as possible
+should use the all uppercase variants of these functions, after
+defining <TT>GC_DEBUG</tt>, and then including <TT>gc.h</tt>.
+In this environment <TT>GC_MALLOC</tt> is a macro which causes
+at least the file name and line number at the allocation point to
+be saved as part of the object. Leak reports will then also include
+this information.
+<P>
+Many collector features (<I>e.g</i> stubborn objects, finalization,
+and disappearing links) are less useful in this context, and are not
+fully supported. Their use will usually generate additional bogus
+leak reports, since the collector itself drops some associated objects.
+<P>
+The same is generally true of thread support. However, as of 6.0alpha4,
+correct leak reports should be generated with linuxthreads.
+<P>
+On a few platforms (currently Solaris/SPARC, Irix, and, with -DSAVE_CALL_CHAIN,
+Linux/X86), <TT>GC_MALLOC</tt>
+also causes some more information about its call stack to be saved
+in the object. Such information is reproduced in the error
+reports in very non-symbolic form, but it can be very useful with the
+aid of a debugger.
+<H2>An Example</h2>
+The following header file <TT>leak_detector.h</tt> is included in the
+"include" subdirectory of the distribution:
+<PRE>
+#define GC_DEBUG
+#include "gc.h"
+#define malloc(n) GC_MALLOC(n)
+#define calloc(m,n) GC_MALLOC((m)*(n))
+#define free(p) GC_FREE(p)
+#define realloc(p,n) GC_REALLOC((p),(n))
+#define CHECK_LEAKS() GC_gcollect()
+</pre>
+<P>
+Assume the collector has been built with -DFIND_LEAK. (For very
+new versions of the collector, we could instead add the statement
+<TT>GC_find_leak = 1</tt> as the first statement in <TT>main</tt>.
+<P>
+The program to be tested for leaks can then look like:
+<PRE>
+#include "leak_detector.h"
+
+main() {
+ int *p[10];
+ int i;
+ /* GC_find_leak = 1; for new collector versions not */
+ /* compiled with -DFIND_LEAK. */
+ for (i = 0; i < 10; ++i) {
+ p[i] = malloc(sizeof(int)+i);
+ }
+ for (i = 1; i < 10; ++i) {
+ free(p[i]);
+ }
+ for (i = 0; i < 9; ++i) {
+ p[i] = malloc(sizeof(int)+i);
+ }
+ CHECK_LEAKS();
+}
+</pre>
+<P>
+On an Intel X86 Linux system this produces on the stderr stream:
+<PRE>
+Leaked composite object at 0x806dff0 (leak_test.c:8, sz=4)
+</pre>
+(On most unmentioned operating systems, the output is similar to this.
+If the collector had been built on Linux/X86 with -DSAVE_CALL_CHAIN,
+the output would be closer to the Solaris example. For this to work,
+the program should not be compiled with -fomit_frame_pointer.)
+<P>
+On Irix it reports
+<PRE>
+Leaked composite object at 0x10040fe0 (leak_test.c:8, sz=4)
+ Caller at allocation:
+ ##PC##= 0x10004910
+</pre>
+and on Solaris the error report is
+<PRE>
+Leaked composite object at 0xef621fc8 (leak_test.c:8, sz=4)
+ Call chain at allocation:
+ args: 4 (0x4), 200656 (0x30FD0)
+ ##PC##= 0x14ADC
+ args: 1 (0x1), -268436012 (0xEFFFFDD4)
+ ##PC##= 0x14A64
+</pre>
+In the latter two cases some additional information is given about
+how malloc was called when the leaked object was allocated. For
+Solaris, the first line specifies the arguments to <TT>GC_debug_malloc</tt>
+(the actual allocation routine), The second the program counter inside
+main, the third the arguments to <TT>main</tt>, and finally the program
+counter inside the caller to main (i.e. in the C startup code).
+<P>
+In the Irix case, only the address inside the caller to main is given.
+<P>
+In many cases, a debugger is needed to interpret the additional information.
+On systems supporting the "adb" debugger, the <TT>callprocs</tt> script
+can be used to replace program counter values with symbolic names.
+As of version 6.1, the collector tries to generate symbolic names for
+call stacks if it knows how to do so on the platform. This is true on
+Linux/X86, but not on most other platforms.
+<H2>Simplified leak detection under Linux</h2>
+Since version 6.1, it should be possible to run the collector in leak
+detection mode on a program a.out under Linux/X86 as follows:
+<OL>
+<LI> Ensure that a.out is a single-threaded executable. This doesn't yet work
+for multithreaded programs.
+<LI> If possible, ensure that the addr2line program is installed in
+/usr/bin. (It comes with RedHat Linux.)
+<LI> If possible, compile a.out with full debug information.
+This will improve the quality of the leak reports. With this approach, it is
+no longer necessary to call GC_ routines explicitly, though that can also
+improve the quality of the leak reports.
+<LI> Build the collector and install it in directory <I>foo</i> as follows:
+<UL>
+<LI> configure --prefix=<I>foo</i> --enable-full-debug --enable-redirect-malloc
+--disable-threads
+<LI> make
+<LI> make install
+</ul>
+<LI> Set environment variables as follows:
+<UL>
+<LI> LD_PRELOAD=<I>foo</i>/lib/libgc.so
+<LI> GC_FIND_LEAK
+<LI> You may also want to set GC_PRINT_STATS (to confirm that the collector
+is running) and/or GC_LOOP_ON_ABORT (to facilitate debugging from another
+window if something goes wrong).
+</ul
+<LI> Simply run a.out as you normally would. Note that if you run anything
+else (<I>e.g.</i> your editor) with those environment variables set,
+it will also be leak tested. This may or may not be useful and/or
+embarrassing. It can generate
+mountains of leak reports if the application wasn't designed to avoid leaks,
+<I>e.g.</i> because it's always short-lived.
+</ol>
+This has not yet been thropughly tested on large applications, but it's known
+to do the right thing on at least some small ones.
