* Fix test_atomic failure caused unaligned AO_double_t access on x86Ivan Maidanski2017-01-244-2/+20
| | | | | | | | | | | | | The failure is caused by violation of an assertion that checks AO_double_t variable is 8-byte aligned on x86. * doc/README.txt (AO_double_t): Add note about required alignment. * src/atomic_ops/sysdeps/standard_ao_double_t.h (AO_double_t): Add comment about alignment. * src/atomic_ops_stack.h (AO_stack_t): Likewise. * tests/test_atomic_include.template (test_atomicXX): Define old_w, w local variables as static (as otherwise, e.g., they could have 4-byte alignment on x86); add comment.
* Revert "Fix test_atomic fail caused unaligned AO_double_t access (VC/x86)"Ivan Maidanski2017-01-247-30/+4
| | | | | | | | | | This reverts commit 69c4010c1b3d43e2e179421e27379aaa5aeeb6d8. The failure is actually caused by the fact that default alignment of stack on x86 is 4 bytes. So, another solution should be proposed to fix the issue for other compilers (and, potentially, other targets). E.g. do not place AO_double_t volatile variables on stack.

* Fix test_atomic failure caused unaligned AO_double_t access on x86 (VC++)Ivan Maidanski2017-01-207-4/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Passing an unaligned AO_double_t pointer to AO double-wide primitives results in an undefined behavior of the latter when running on x86 (or violation of the corresponding assertion on the alignment). MS VC++/x86 aligns AO_double_t values on a 4-byte boundary by default. For the proper alignment, __declspec(align(8)) should be applied to variables defined in the client code (which uses double-wide AO primitives). Unfortunately, the attribute cannot be added to AO_double_t definition itself because the compiler does not allow the attribute for function arguments. This patch introduces AO_DOUBLE_ALIGN attribute for use by clients of the double-wide AO primitives (and, thus, AO_stack clients). Matters only Visual Studio compiler for X86. The inner clients (atomic_ops_malloc, test_atomic, test_stack) are updated to use this attribute. * doc/README_win32.txt [x86] (AO_DOUBLE_ALIGN): Document. * src/atomic_ops/sysdeps/generic_pthread.h (AO_DOUBLE_ALIGN): Define (as empty). * src/atomic_ops/sysdeps/standard_ao_double_t.h [!_WIN64 && _WIN32 && !__GNUC__ && _MSC_VER] (AO_DOUBLE_ALIGN): Define as declspec align(8); document it. * src/atomic_ops/sysdeps/standard_ao_double_t.h [!AO_DOUBLE_ALIGN] (AO_DOUBLE_ALIGN): Define as empty (otherwise). * src/atomic_ops_stack.h [AO_USE_ALMOST_LOCK_FREE && !AO_DOUBLE_ALIGN] (AO_DOUBLE_ALIGN): Likewise. * src/atomic_ops_malloc.c (AO_free_list): Use AO_DOUBLE_ALIGN attribute. * tests/test_stack.c (the_list): Likewise. * src/atomic_ops_stack.h [!AO_USE_ALMOST_LOCK_FREE] (AO_stack_t): Document AO_DOUBLE_ALIGN usage (by clients). * tests/test_atomic_include.template (test_atomicXX): Use AO_DOUBLE_ALIGN attribute for old_w and w double-wide local variables (to avoid alignment assertion violation or AO primitives undefined behavior on x86 if the test code is compiled by VC++).

* Add *_and/or/xor* and *_[fetch_]compare_and_swap* tests to test_atomicIvan Maidanski2016-11-011-0/+182
| | | | | | | | | | | | | Previously, only AO_and/or/xor and AO_[fetch]_CAS tests (for AO_t) existed in test_atomic. * tests/test_atomic_include.template (test_atomicXX): Add minimal testing of AO_short_compare_and_swapXX, AO_short_orXX, AO_short_xorXX, AO_short_andXX, AO_short_fetch_compare_and_swapXX, AO_char_compare_and_swapXX, AO_char_orXX, AO_char_xorXX, AO_char_andXX, AO_char_fetch_compare_and_swapXX, AO_int_compare_and_swapXX, AO_int_orXX, AO_int_xorXX, AO_int_andXX, AO_int_fetch_compare_and_swapXX.
* Fix reporting about missing and/or/xor_dd_acquire_read (test_atomic)Ivan Maidanski2016-11-011-3/+18
| | | | | | | | | | | | | | | AO_XSIZE_and/or/xor_dd_acquire_read are meaningless and not implemented, thus their absence is not reported in the tests. * tests/test_atomic_include.template [!AO_HAVE_orXX] (test_atomicXX): Do not call MISSING(AO_or) if all AO_HAVE_or* excluding AO_HAVE_or_dd_acquire_read are not defined. * tests/test_atomic_include.template [!AO_HAVE_xorXX] (test_atomicXX): Do not call MISSING(AO_xor) if all AO_HAVE_xor* excluding AO_HAVE_xor_dd_acquire_read are not defined. * tests/test_atomic_include.template [!AO_HAVE_andXX] (test_atomicXX): Do not call MISSING(AO_and) if all AO_HAVE_and* excluding AO_HAVE_and_dd_acquire_read are not defined.
* Fix missing double_compare_and_swap_dd_acquire_readIvan Maidanski2016-11-011-0/+16
| | | | | | | | | | This matters only if AO_double_compare_and_swap[_acquire_read] actually defined in generalize.h too. * src/atomic_ops/generalize.h [!AO_HAVE_double_compare_and_swap_dd_acquire_read] (AO_double_compare_and_swap_dd_acquire_read): Define (same as definition as auto-generated in generalize-small.h).
* Workaround 'value of MAP_ANON unknown' cppcheck info messageIvan Maidanski2016-10-261-1/+3
| | | | | | | | (fix commit 4c303bc) * src/atomic_ops_malloc.c [USE_MMAP_ANON && CPPCHECK] (OPT_MAP_ANON): Define to immediate non-zero value (taken from Linux libc) instead of MAP_ANON (because the latter is used in ifdef).
* Suppress 'ISO C does not support __int128 type' GCC/Clang pedantic warningIvan Maidanski2016-10-251-1/+15
| | | | | | * src/atomic_ops/sysdeps/standard_ao_double_t.h [!__ILP32__ && (__GNUC__ >= 4.7 || __clang__ >= 3.6)] (double_ptr_storage): Turn off pedantic warnings reporting (for this typedef only).
* Fix test_malloc failure if CPPCHECK is definedIvan Maidanski2016-10-251-2/+2
| | | | | | | (fix commit c1a7aad) * src/atomic_ops_malloc.c [USE_MMAP_ANON && MAP_ANONYMOUS] (OPT_MAP_ANON): Define to MAP_ANON (instead of 0) if CPPCHECK.
