 981         version.

1004
1005         * src/atomic_ops/Makefile.am: Change function naming from "byte" to

1007
1008 [1.0 release]
1009
1010 2005-03-21  Hans Boehm <Hans.Boehm@hp.com>
1011         Fix various acquire_release_volatile.h files to reflect the fact
1012         that both icc and gcc seem to reorder ordinary memory accesses around
1013         volatile accesses early in the compilation. Modify the acquire
1014         release test to catch this problem (with high probability, and only on
1015         a multiprocessor).
1016
1017 2005-03 Hans Boehm <Hans.Boehm@hp.com>
1018         Fixes for recently introduced bugs.  Update x86 and x86-64 assembly
1019         syntax to deal with complaints by some recent gcc versions.
1020

1026         Hans Boehm <Hans.Boehm@hp.com>
1027         Use autoconf, automake, starting with code from Debian package.
1028         Don't use libtool.
1029
1030 2005-01 Hans Boehm <Hans.Boehm@hp.com>
1031         * test_and_set_t_is_ao_t.h, test_and_set_t_is_char.h, others:

1033
1034 2005-01 Hans Boehm <Hans.Boehm@hp.com>
1035         * ao_t_is_int.h: Add to trivially support int-wide operations

1039         * gcc/powerpc.h: First serious attempt to support PowerPC (with
1040         help from Maged Michael and others).
1041

1043         * sunc/sparc.[hS]: Added minimal support for the Sun SPARC compiler.
1044         * atomic_ops_sysdeps.S: Add support for platforms that require
1045         out-of-line assembly code.
1046
1047 2004-10 Hans Boehm <Hans.Boehm@hp.com>
1048         More work on char, short, int sized data.  Add both
1049         compare_double_and_swap_double and compare_and_swap_double.
1050         Typically each platform will provide at most one of these.
1051
1052 2004-07-02  Ranko Zivojnovic
1053         Replace both instances of AO_HAVE_NOP_FULL with AO_HAVE_nop_full.

1059
1060         * atomic_ops/sysdeps/acquire_release_volatile.h, atomic_ops.h:
1061         Fix support for ecc on IA64.  Remove compiler_barrier workaround
1062         for gcc 3.4 and later.
1063
1064 2003-12-17  Hans Boehm  <Hans.Boehm@hp.com>
1065
1066         * atomic_ops/sysdeps/hpc/{ia64.h,hppa.h},
1067         atomic_ops/sysdeps/msftc/x86.h, Makefile, Makefile.atomic_ops,
1068         Makefile.atomic_ops.msft, atomic_ops.h: Add initial support
1069         for atomic_ops for VC++/Windows/X86 and HP/UX with the HP
1070         compiler on PA_RISC and IA64.
1071
1072 2003-12-09  Hans Boehm  <Hans.Boehm@hp.com>
1073
1074         * many: Install under "atomic_ops" instead of "ao".
1075         Change atomic_ops include file structure.  Auxiliary include
1076         files are all under include/atomic_ops.
1077         Fix (hopefully) "make dist" in atomic_ops distribution.
1078         Renamed various types to end in _t, though the old versions
1079         are still defined for backward compatibility.
1080
1081 2003-12-08  Carlos O'Donell  <carlos@baldric.uwo.ca>

1084         AO_pa_clearable_loc type. Add __ldcw, and __ldcw_align
1085         helper macros. AO_test_and_set_full uses helper macros.
1086
1087
1088 Started sometime after version 0.4 release.  Currently the format is
1089 informal.  Eventually should become more GNU-like.
