* configure.ac: Replaced HAS_I386_THREAD_STATE_* with
HAS_X86_THREAD_STATE32_* and HAS_X86_THREAD_STATE64_* respectively.
* configure: Regenerated.
* include/private/gcconfig.h (DARWIN): Added X86_64 define for Darwin.
Added base definitions for the X86_64 Darwin port.
* include/private/gc_priv.h: Added definitions for Darwin MACH thread
operations. Moved existing THREAD_STATE info from darwin_stop_world.c.
* darwin_stop_world.c: Removed THREAD_STATE info. Added
HAS_X86_THREAD_STATE64___RAX. And replaced HAS_I386_THREAD_STATE___EAX
with HAS_X86_THREAD_STATE32___EAX.
(GC_push_all_stacks): Use GC_MACH_THREAD_STATE_COUNT. Add code for
X86_64 Darwin.
* dyn_load.c (GC_dyld_name_for_hdr): Use GC_MACH_HEADER.
(GC_dyld_image_add): Use GC_MACH_HEADER and GC_MACH_SECTION.
Distinguish between getsectbynamefromheader_64 and
getsectbynamefromheader.
(GC_dyld_image_remove): Likewise.
* os_dep.c (GC_dirty_init): Use GC_MACH_THREAD_STATE.
(catch_exception_raise): Introduce exception information for I386 and
X86_64 Darwin. Add X86_64 for exc_state.faultvaddr.

* os_dep.c (GC_linux_stack_base): Check for bug present in some
Sparc glibc variants where __libc_stack_end is erroneously set
to "1". Fallback to procfs code in that case.

statically initialized it to TRUE if compiling with GCC.

compiling with GCC.

* finalize.c:
- Accomodate finalization requests for static objects.
(Will be required by hash synchronization. May be needed
in some configurations now.)
* gc_priv.h:
- Define MIN_WORDS. All allocation requests are rounded
up to at least this size. Removes a subtle assumption that
Java objects have a 2 word header.
* gcconfig.h:
- Adjust Linux/IA64 configuration for non-ancient kernels.
(Necessary fix for IA64.)
* linux_threads.c:
- Fix syntax error in currently unused code. Will be needed
for Linux/PA-RISC.
* malloc.c:
- Handle MIN_WORDS.
* misc.c:
- Handle MIN_WORDS.
- Change stack cleaning code to typically clear about one tenth
the memory it used to in the threads configuration. Occasionally
still clear more. (This is really a fix for a long-standing
and fairly significant performance bug with threads.)
* os_dep.c:
- Fix the code for finding the beginning of the data segment under
Linux. I believe this is necessary for some IA64 Linux
distributions. It will also helo other platforms, though those
may additionally require a gcconfig.h adjustment. (This basically
works around the absence of a data_start or __data_start
definition in glibc.)
* test.c:
- Handle rounding due to MIN_WORDS.

* gcconfig.h (SPARC): Define ALIGNMENT to 8 for 64bit SPARC.

Make STACKBOTTOM depend on the wordsize.

Linux.

for PowerPC Linux.
