1031 [1.0 release]
1032
1033 2005-03-21  Hans Boehm <Hans.Boehm@hp.com>
1034         Fix various acquire_release_volatile.h files to reflect the fact
1035         that both icc and gcc seem to reorder ordinary memory accesses around
1036         volatile accesses early in the compilation. Modify the acquire
1037         release test to catch this problem (with high probability, and only on
1038         a multiprocessor).

1049         Hans Boehm <Hans.Boehm@hp.com>

1052
1053 2005-01 Hans Boehm <Hans.Boehm@hp.com>
1054         * test_and_set_t_is_ao_t.h, test_and_set_t_is_char.h, others:

1057 2005-01 Hans Boehm <Hans.Boehm@hp.com>
1058         * ao_t_is_int.h: Add to trivially support int-wide operations

1068         out-of-line assembly code.
1069
1070 2004-10 Hans Boehm <Hans.Boehm@hp.com>
1071         More work on char, short, int sized data.  Add both
1072         compare_double_and_swap_double and compare_and_swap_double.
1073         Typically each platform will provide at most one of these.
1074
1075 2004-07-02  Ranko Zivojnovic
1076         Replace both instances of AO_HAVE_NOP_FULL with AO_HAVE_nop_full.

1088
1089         * atomic_ops/sysdeps/hpc/{ia64.h,hppa.h},
1090         atomic_ops/sysdeps/msftc/x86.h, Makefile, Makefile.atomic_ops,
1091         Makefile.atomic_ops.msft, atomic_ops.h: Add initial support
1092         for atomic_ops for VC++/Windows/X86 and HP/UX with the HP
1093         compiler on PA_RISC and IA64.
1094
1095 2003-12-09  Hans Boehm  <Hans.Boehm@hp.com>
1096
1097         * many: Install under "atomic_ops" instead of "ao".

1099         files are all under include/atomic_ops.
1100         Fix (hopefully) "make dist" in atomic_ops distribution.
1101         Renamed various types to end in _t, though the old versions
1102         are still defined for backward compatibility.
1103
1104 2003-12-08  Carlos O'Donell  <carlos@baldric.uwo.ca>

1107         AO_pa_clearable_loc type. Add __ldcw, and __ldcw_align
1108         helper macros. AO_test_and_set_full uses helper macros.
1109
1110
1111 Started sometime after version 0.4 release.  Currently the format is
1112 informal.  Eventually should become more GNU-like.
