local variable.
* misc.c (GC_clear_stack_inner): Store address of volatile 'dummy'

invocation to prevent a tail-call optimization.

(if GC_OPENBSD_THREADS).

calling pthread_stackseg_np (subtracting ss_size from ss_sp) instead
of retrieving it from OpenBSD pthread implementation-dependent context
(if GC_OPENBSD_THREADS); remove comment.
2012-06-17 Ivan Maidanski <ivmai@mail.ru>
* tests/initsecondarythread.c: Include "private/config.h" if
HAVE_CONFIG_H (mostly to have GC_WIN32_PTHREADS defined for

"cmd" WinMain argument for NULL (in that case "argc" local variable is
set to 0).
2012-06-16 Ivan Maidanski <ivmai@mail.ru>
* tests/test_cpp.cc (main): Call GC_set_all_interior_pointers(1)
before GC_INIT to ensure that the collector considers pointers to
object interiors as valid ones (such a pointer could emerge as
a result of a type cast to subclass in case of multiple inheritance);
add comment.
The results of GC_MALLOC_ATOMIC, GC_get_maps, and GC_scratch_alloc
are now properly checked, avoiding segmentation faults. Several
private symbols have been made externally visible to aid third
party software which unfortunately relies on them. Minor NetBSD
issues have been resolved.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
Replace first hunk of patch-af with CONFIGURE_ARGS.
Remove next two hunks of patch-af installing some private headers.
This shouldn't be necessary in the 7.x versions. If it is, the author
is willing to help fix the underlying problems.
patch-aa and -ab will be included in the next upstream release.

Changes relative to 6.8 include, in no particular order:
- Change C code to require at least C89. Clean up code in various
other respects.
- Win64 port.
- Always count how much live data there is in the heap. Add more
robust heap expansion heuristic which relies on this.
- Remove old-style Solaris threads support and some other obsolete
platform support.
- Restructure mark code, hopefully resulting in some performance
improvements.
- Change the GC code to traffic mostly in either bytes or allocation
granules, not words, internally.
- Provide for fast inline allocation that requires less frequent client
recompilations. (Needs more testing.)
- Removed SILENT configuration macro and PRINTSTATS and GATHERSTATS
macros. Control is now via GC_PRINT_STATS and GC_PRINT_VERBOSE_STATS
encironment variables.
- Thread local allocation is now performed without needing to call
special allocation functions. The configuration macro
THREAD_LOCAL_ALLOC
continues to determine whether this is supported.
- Thread local allocation is supported on more platforms.
- Win32 threads code was rewritten and is hopefully more sane.
- Allocation routines now decide whether to lock dynamically, based on
whether a second thread has been created.
- Mostly untested support for a compiler write barrier.
- Use libatomic_ops for atomic operations.
- Limited support for malloc redirection with Linux threads (& NPTL ).
- Various bug fixes and some new platform support.
configure script since pkgsrc will set MACHINE_GNU_PLATFORM to
sparc-sun-solaris2 on a solaris/sparc machine. This gets this package closer
to building on solaris with the sunpro compiler.
Changes since 6.7:
- Added some support for Dragonfly BSD. (Thanks to Joerg Sonnenberger and
Thomas Klausner.)
- Improvements to the HP/UX section of configure.in.
(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)
- Applied a long-lost MINGW patch from Gerard Allan for malloc redirection
with threads. This one probably makes no sense for 7.0, and was not applied
there.
- The Solaris/SPARC definition of GC_INIT() in gc.h wasn't C++-compilable.
and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.
For example, "make show-buildlink3" in fonts/Xft2 displays:
zlib
fontconfig
iconv
zlib
freetype2
expat
freetype2
Xrender
renderproto
RECOMMENDED is removed. It becomes ABI_DEPENDS.
BUILDLINK_RECOMMENDED.foo becomes BUILDLINK_ABI_DEPENDS.foo.
BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo.
BUILDLINK_DEPENDS does not change.
IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS
which defaults to "yes".
Added to obsolete.mk checking for IGNORE_RECOMMENDED.
I did not manually go through and fix any aesthetic tab/spacing issues.
I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.
I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.
As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.
As discussed on tech-pkg.
I will commit to revbump, pkglint, pkg_install, createbuildlink separately.
Note that if you use wip, it will fail! I will commit to pkgsrc-wip
later (within day).
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__.
- Fix ppc 64 test_and_set code by removing it. (Thanks to Christian
Thalinger.)
- Add prototypes for GC_finalizer_notifier and GC_thr_init. (Thanks to
David Ayers.)
- Use ld instead of nonexistent 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
minimally tested 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.
- Fix Makefile.am, so it handles exe extensions under Cygwin correctly
for gctest.
