2012-08-05  Ivan Maidanski <ivmai@mail.ru>

	* config.guess: Regenerate (by autoreconf -vif using autoconf-2.68,
	automake-1.11.1 and libtool-2.4).
	* config.sub: Likewise.
	* m4/libtool.m4: Likewise.

2012-08-02  Ivan Maidanski <ivmai@mail.ru>

	* misc.c (GC_clear_stack_inner): Use GC_approx_sp() instead of
	"dummy[0]" set to "&dummy" value (that worked as expected only for
	STACK_GROWS_DOWN case).

2012-08-02  Ivan Maidanski <ivmai@mail.ru>

	* alloc.c (min_bytes_allocd, GC_stopped_mark): Use GC_approx_sp()
	instead of "&dummy"; remove 'dummy' local variable.
	* dyn_load.c (GC_cond_add_roots): Likewise.
	* misc.c (GC_init): Likewise.
	* os_dep.c (GC_get_stack_base, GC_get_main_stack_base): Likewise.
	* pthread_stop_world.c (GC_suspend_handler_inner,
	nacl_pre_syscall_hook, __nacl_suspend_thread_if_needed): Likewise.
	* pthread_support.c (GC_thr_init): Likewise.
	* ptr_chck.c (GC_on_stack): Likewise.
	* win32_threads.c (GC_push_stack_for): Likewise.
	* extra/setjmp_t.c (main): Define volatile 'sp' local variable, store
	its address to it and use it instead of "&dummy"; remove 'dummy' local
	variable.
	* mach_dep.c (GC_with_callee_saves_pushed): Use volatile for 'dummy'
	local variable.
	* misc.c (GC_clear_stack_inner): Store address of volatile 'dummy'
	local array (i.e. 'sp' value) to its first element (and use it in the
	comparison of addresses) to prevent any harmful optimizations as C
	officially disallows comparisons of pointers to different objects
	(e.g., some Mac OS X clang releases might turn a conditional
	expression that uses 'dummy' address into a constant); update comment.
	* misc.c (GC_call_with_stack_base): Use "&base" instead of "&dummy"
	(it is safe to use address of base here); remove dummy variable.

2012-08-01  Ivan Maidanski <ivmai@mail.ru>

	* misc.c (GC_call_with_stack_base): Call GC_noop1 after fn()
	invocation to prevent a tail-call optimization.

2012-07-21  Ivan Maidanski <ivmai@mail.ru>

	* os_dep.c (GC_get_stack_base): Abort if pthread_stackseg_np fails
	(if GC_OPENBSD_THREADS).
	* pthread_stop_world.c (GC_suspend_all): Get correct stack_ptr by
	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
	pthreads-w32 target).
	* tests/thread_leak_test.c: Likewise.
	* tests/threadkey_test.c: Likewise.

2012-06-16  Ivan Maidanski <ivmai@mail.ru>

	* tests/test_cpp.cc (WinMain): Prevent SEGV in strtok() by checking
	"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.

[7.2c]

2012-06-11  Ivan Maidanski <ivmai@mail.ru>

	* doc/README: Change version to 7.2c (rev. C).

2008-07-25  Hans Boehm <Hans.Boehm@hp.com> (Really mostly Ivan Maidanski)

	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.
