- 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.)
- Fixed print_block_list to print the correct kind number for
STUBBORN. (Thanks to Rutger Ovidus.)
- 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.)
- GC_allochblk_nth incremented GC_words_wasted by bytes rather than
words.
- 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.
