23 all_acquire_release_volatile.h, instead of just the pointer-sized
25 *src/atomic_ops/sysdeps/gcc/ia64.h: Include
26 all_acquire_release_volatile.h and all_atomic_load_store.h,
27 instead of just the pointer-sized versions.
31 2005-09-27 Hans Boehm <Hans.Boehm@hp.com>
32 *src/atomic_ops.h: Define AO_CAN_EMUL_CAS for arm.
33 *src/atomic_ops/sysdeps/read_ordered.h: New file, extracted from

39 2005-09-16 Hans Boehm <Hans.Boehm@hp.com>
40 *src/atomic_ops/sysdeps/gcc/arm.h: Replace the AO_test_and_set
41 definition with one that might actually work. (Thanks to Kazu
42 Hirata and Paul Brook.)
44 2005-08-01 Hans Boehm <Hans.Boehm@hp.com>
45 *src/atomic_ops/Makefile.am: Change function naming from "byte" to
50 2005-03-21 Hans Boehm <Hans.Boehm@hp.com>
51 Fix various acquire_release_volatile.h files to reflect the fact
52 that both icc and gcc seem to reorder ordinary memory accesses around
53 volatile accesses early in the compilation. Modify the acquire
54 release test to catch this problem (with high probablity, and only on
57 2005-03 Hans Boehm <Hans.Boehm@hp.com>
58 Fixes for recently introduced bugs. Update x86 and x86-64 assembly
59 syntax to deal with complaints by some recent gcc versions.
61 2005-02 Hans Boehm <Hans.Boehm@hp.com>
62 Added libatomic_ops_gpl library with support for mostly
63 lock-free stack and malloc().
65 2005-01 Ian Wienand <ianw@gelato.unsw.edu.au>, Al Stone <ahs3@debian.org>,
66 Hans Boehm <Hans.Boehm@hp.com>
67 Use autoconf, automake, starting with code from Debian package.
70 2005-01 Hans Boehm <Hans.Boehm@hp.com>
71 * test_and_set_t_is_ao_t.h, test_and_set_t_is_char.h, others:
72 Change most platforms to use byte-wide test-and-set locations.
74 2005-01 Hans Boehm <Hans.Boehm@hp.com>
75 * ao_t_is_int.h: Add to trivially support int-wide operations
76 on platforms with int-sized pointers.
78 2004-12 Hans Boehm <Hans.Boehm@hp.com>
79 * gcc/powerpc.h: First serious attempt to support PowerPC (with
80 help from Maged Michael and others).
82 2004-12 Hans Boehm <Hans.Boehm@hp.com>
83 * sunc/sparc.[hS]: Added minimal supprt for the Sun SPARC compiler.
84 * atomic_ops_sysdeps.S: Add support for platforms that require
85 out-of-line assmebly code.
87 2004-10 Hans Boehm <Hans.Boehm@hp.com>
88 More work on char, short, int sized data. Add both
89 compare_double_and_swap_double and compare_and_swap_double.
90 Typically each platform will provide at most one of these.
92 2004-07-02 Ranko Zivojnovic
93 Replace both instances of AO_HAVE_NOP_FULL with AO_HAVE_nop_full.
95 2004-06 Hans Boehm <Hans.Boehm@hp.com>
96 Start to add atomic_ops primitives for different sized data.
98 2003-12-18 Hans Boehm <Hans.Boehm@hp.com>
99 * atomic_ops/sysdeps/acquire_release_volatile.h, atomic_ops.h:
100 Fix support for ecc on IA64. Remove compiler_barrier workaround
101 for gcc 3.4 and later.
103 2003-12-17 Hans Boehm <Hans.Boehm@hp.com>
104 * atomic_ops/sysdeps/hpc/{ia64.h,hppa.h},
105 atomic_ops/sysdeps/msftc/x86.h, Makefile, Makefile.atomic_ops,
106 Makefile.atomic_ops.msft, atomic_ops.h: Add initial support
107 for atomic_ops for VC++/Windows/X86 and HP/UX with the HP
108 compiler on PA_RISC and IA64.
110 2003-12-09 Hans Boehm <Hans.Boehm@hp.com>
112 * many: Install under "atomic_ops" instead of "ao".
113 Change atomic_ops include file structure. Auxiliary include
114 files are all under include/atomic_ops.
115 Fix (hopefully) "make dist" in atomic_ops distribution.
116 Renamed various types to end in _t, though the old versions
117 are still defined for backward compatibility.
119 2003-12-08 Carlos O'Donell <carlos@baldric.uwo.ca>
121 * ao_sysdeps/gcc/hppa.h: Define AO_CLEAR macro. Change
122 AO_pa_clearable_loc type. Add __ldcw, and __ldcw_align
123 helper macros. AO_test_and_set_full uses helper macros.
126 Started sometime after version 0.4 release. Currently the format is
127 informal. Eventually should become more GNU-like.
