2008-11-07 Hans Boehm <Hans.Boehm@hp.com> (Really Ivan Maidansky)
(Mostly improves LLP64 support.)
* backgraph.c, checksums.c, dbg_mlc.c, finalize.c, mark.c,
misc.c, reclaim.c: Changed some int and long type to word or size_t
(and vice versa where appropriate)
* gcj_mlc.c, include/private/dbg_mlc.h, include/private/gcconfig.h,
include/private/thread_local_alloc.h, mark.c,
misc.c, thread_local_alloc.c, win32_threads.c: Added intermediate
casts to word type when casting from int to pointer (or pointer
to int, or data pointer to code pointer) - just to remove the
corresponding compiler warning.
* ptr_chck.c (GC_is_visible): cast int const to word type to
prevent left shift overflow.
* os_dep.c: change the type of GC_mem_top_down global var
(containing a flag) to DWORD.
* include/gc_config_macros.h: define GC_SOLARIS_THREADS if GC_THREADS
is defined on SunOS x86_64.
* misc.c (GC_init_size_map): Ifdef out GC_ASSERT as a workaround
for VC++ 2008 amd64 (v15.00.21022.08 for x64) compiler bug
(the compiler gets hung if invoked with -Ox -D
ALL_INTERIOR_POINTERS -D GC_ASSERTIONS)
* backgraph.c: cast GC_gc_no value to unsigned short when
assigned/compared to height_gc_no field of back_edges.
* os_dep.c (GC_remove_protection): Add ARGSUSED.
* win32_threads.c (GC_thread_exit_proc): Remove unused local var.
* mark.c (GC_check_dirty): Move declaration out of func body.
