* Ensure result of AO_test_and_set is always AO_TS_CLEAR or AO_TS_SETIvan Maidanski2022-08-121-4/+8
| | | | | | | | | | | | | | (fix of commit cbbf8633) According to the GCC manual, __atomic_test_and_set() result type is Bool, thus it is not guaranteed to return AO_TS_SET value. (E.g., the function may return 1 while AO_TS_SET is 255, as observed on sparc64 with gcc-12.) * src/atomic_ops/sysdeps/gcc/generic.h [!AO_PREFER_GENERALIZED] (AO_test_and_set, AO_test_and_set_acquire, AO_test_and_set_release, AO_test_and_set_full): Return AO_TS_SET if __atomic_test_and_set() result is non-zero, AO_TS_CLEAR otherwise.
* Avoid AO_stack_t to cross CPU cache line boundaryIvan Maidanski2022-08-121-1/+31
| | | | | | | | | | | | | | | (a cherry-pick of commit ed712f7dc from 'release-7_6') Issue #45 (libatomic_ops). Enforce proper alignment of AO_stack_t.AO_ptr to avoid the structure value to cross the CPU cache line boundary. A workaround for almost-lock-free push/pop test failures on aarch64, at least. * src/atomic_ops_stack.h [AO_USE_ALMOST_LOCK_FREE && !AO_STACK_ATTR_ALLIGNED] (AO_STACK_ATTR_ALLIGNED): Define. * src/atomic_ops_stack.h [AO_USE_ALMOST_LOCK_FREE] (AO_stack_t.AO_ptr): Add AO_STACK_ATTR_ALLIGNED attribute.
* Repeat black list check on CAS fail in stack_push_explicit_aux_releaseIvan Maidanski2022-08-121-6/+4
| | | | | | | | | | | | | (a cherry-pick of commit ae0f8e7e4 from 'release-7_4') Also, execute the first read in a loop with an acquire barrier, and place black list checking as close to CAS as possible. * src/atomic_ops_stack.c [AO_USE_ALMOST_LOCK_FREE] (AO_stack_push_explicit_aux_release): Use acquire barrier to read list value (stored to next local variable); read list value and store it to x element before iterating over AO_stack_bl (and, thus, retry iterating over AO_stack_bl if CAS failed).
