* Eliminate 'atomic_thread_fence is unsupported with tsan' gcc-11 warningIvan Maidanski2023-03-311-1/+5
| | | | | | | | | | | | The workaround is to use __atomic_test_and_set instead of __atomic_thread_fence in case of option -fsanitize=thread is passed to gcc (or clang). The old behavior could be turned on by defining AO_USE_ATOMIC_THREAD_FENCE macro. * src/atomic_ops/sysdeps/gcc/generic.h [!AO_UNIPROCESSOR && AO_THREAD_SANITIZER && !AO_USE_ATOMIC_THREAD_FENCE] (AO_nop_read, AO_nop_write, AO_nop_full): Do not define (using __atomic_thread_fence); add comment.

| | | | | | | | | | | | * src/atomic_ops_malloc.c [HAVE_MMAP] (AO_malloc_large): Change type of result local variable from char* to void*. * src/atomic_ops_malloc.c [HAVE_MMAP] (AO_free_large): Change type of argument from char* to void*. * src/atomic_ops_malloc.c (add_chunk_as): Cast to AO_t* from void* directly (adjust ofs accordingly); add assertion that sz is multiple of AO_t size. * src/atomic_ops_malloc.c (AO_free): Remove cast to char* in AO_free_large() call.
* Fix AO_compare_and_swap_full asm code for clang on sparcIvan Maidanski2022-08-101-12/+6
| | | | | | | | | | | | | | | | Issue #52 (libatomic_ops). The issue (SIGSEGV in test_malloc) is observed with clang-13, at least. The workaround is to simplify asm code of AO_compare_and_swap_full (moving the comparison of CAS result and old value to C code). * src/atomic_ops/sysdeps/gcc/sparc.h [(!(AO_GNUC_PREREQ(12,0) || AO_CLANG_PREREQ(13,0)) || AO_DISABLE_GCC_ATOMICS) && !AO_NO_SPARC_V9 && !AO_GENERALIZE_ASM_BOOL_CAS] (AO_compare_and_swap_full): Remove ret local variable; remove cmp, be, mov, clr instructions from asm block (to match that of AO_fetch_compare_and_swap_full); remove cc from asm block clobbers; change specifier for old input operand of asm block (from "0" to "r"); return new_val==old instead of ret.
* Use GCC atomic intrinsics for sparcIvan Maidanski2022-08-011-2/+9
| | | | | | | | | | | | | | | | | The intrinsics are used in gcc/sparc.h (unless AO_DISABLE_GCC_ATOMICS) starting from gcc-12 and clang-13. * src/atomic_ops/sysdeps/gcc/sparc.h: Remove TODO item that support is incomplete and about compare-and-swap. * src/atomic_ops/sysdeps/gcc/sparc.h [(AO_GNUC_PREREQ(12,0) || AO_CLANG_PREREQ(13,0)) && !AO_DISABLE_GCC_ATOMICS]: Include generic.h; do not include all_atomic_load_store.h, ordered_except_wr.h, test_and_set_t_is_char.h. * src/atomic_ops/sysdeps/gcc/sparc.h [(AO_GNUC_PREREQ(12,0) || AO_CLANG_PREREQ(13,0)) && !AO_DISABLE_GCC_ATOMICS] (AO_test_and_set_full, AO_compare_and_swap_full, AO_fetch_compare_and_swap_full): Do not define as an asm-based implementation.
* Properly place comment about minimal support in tile.hIvan Maidanski2022-07-301-2/+2
| | | | | * src/atomic_ops/sysdeps/gcc/tile.h: Move comment that the support is minimal to AO_DISABLE_GCC_ATOMICS part of code.
* Ensure result of AO_test_and_set is always AO_TS_CLEAR or AO_TS_SETIvan Maidanski2022-07-291-4/+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 Maidanski2022-02-201-1/+31
| | | | | | | | | | | | | Issue #45 (libatomic_ops). Enforce proper alignment of AO_stack_t.AO_pa 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_STACK_ATTR_ALLIGNED] (AO_STACK_ATTR_ALLIGNED): Define. * src/atomic_ops_stack.h (AO_stack_t.AO_pa): Add AO_STACK_ATTR_ALLIGNED attribute.
* Repeat black list check on CAS fail in stack_push_explicit_aux_releaseIvan Maidanski2022-02-201-9/+8
| | | | | | | | | | | 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).
* Remove redundant assert in AO_stack_pop_explicit_aux_acquireIvan Maidanski2022-02-191-2/+1
| | | | | | * src/atomic_ops_stack.c [AO_USE_ALMOST_LOCK_FREE] (AO_stack_pop_explicit_aux_acquire): Remove assertion about i; replace "First" to "first" in comment.

| | | | | | | | | | | | | | (fix of commit d29c0910d) * src/atomic_ops_stack.c (AO_real_head_ptr): Rename to AO_stack_head_ptr. * src/atomic_ops_stack.h (AO_real_head_ptr): Likewise. * src/atomic_ops_stack.c (AO_real_next_ptr): Rename to AO_stack_next_ptr. * src/atomic_ops_stack.h (AO_real_next_ptr): Likewise. * src/atomic_ops_stack.h [!AO_REAL_PTR_AS_MACRO] (AO_REAL_NEXT_PTR, AO_REAL_HEAD_PTR): Rename AO_real_head_ptr and AO_real_next_ptr to AO_stack_head_ptr and AO_stack_next_ptr, respectively.
* New AO_stack_is_lock_free API functionIvan Maidanski2022-02-182-0/+10
| | | | | | | | | | * README_stack.txt: Document AO_stack_is_lock_free; update documentation about AO_STACK_IS_LOCK_FREE. * src/atomic_ops_stack.c (AO_stack_is_lock_free): Implement. * src/atomic_ops_stack.h (AO_stack_is_lock_free): New API function declaration. * tests/test_stack.c (main): Use !AO_stack_is_lock_free() instead of AO_USE_ALMOST_LOCK_FREE.

* Move gcc-4/alpha workaround outside AO_stack_pop_explicit_aux_acquireIvan Maidanski2022-02-171-12/+9
| | | | | | | | | | | | (refactoring) * src/atomic_ops_stack.c [AO_USE_ALMOST_LOCK_FREE && __alpha__ && __GNUC__==4] (AO_EXPECT_FALSE): Redefine to expr (before AO_stack_push_explicit_aux_release); move comment from AO_stack_pop_explicit_aux_acquire. * src/atomic_ops_stack.c [AO_USE_ALMOST_LOCK_FREE && __alpha__ && __GNUC__==4] (AO_stack_pop_explicit_aux_acquire): Use AO_EXPECT_FALSE (in the same way as for non-alpha case).
* Fix sizeof passed to memset in AO_stack_initIvan Maidanski2022-02-151-1/+1
| | | | | | | (fix of commit e477b79ef) * src/atomic_ops_stack.c (AO_stack_init): Pass sizeof(AO_stack_t) to memset() instead of sizeof pointer; remove redundant cast of list.
* Use builtin_expect in AO_stack_push_explicit_aux_releaseIvan Maidanski2022-02-151-2/+2
| | | | | | * src/atomic_ops_stack.c [AO_USE_ALMOST_LOCK_FREE] (AO_stack_push_explicit_aux_release): Use AO_EXPECT_FALSE() in comparison of entries and x_bits.
* Do not expose AO_REAL_HEAD/NEXT_PTR implementation in header by defaultIvan Maidanski2022-02-152-18/+37
| | | | | | | | | | | | | | | | | | | | | | | | Now AO_REAL_HEAD_PTR() and AO_REAL_NEXT_PTR() macros definition does not depend on whether the implementation is almost or fully lock-free. These macros just call the relevant implementation-dependent API function (AO_real_head_ptr or AO_real_next_ptr, respectively). If needed, the client could define AO_REAL_PTR_AS_MACRO (prior to include atomic_ops_stack.h) to continue using implementation-dependent definition of AO_REAL_HEAD_PTR and AO_REAL_NEXT_PTR macros. * src/atomic_ops_stack.c [!AO_REAL_PTR_AS_MACRO] (AO_REAL_PTR_AS_MACRO): Define (before include atomic_ops_stack.h). * src/atomic_ops_stack.c (AO_real_head_ptr, AO_real_next_ptr): Implement. * src/atomic_ops_stack.h [AO_USE_ALMOST_LOCK_FREE] (AO_stack_push_explicit_aux_release): Rename argument. * src/atomic_ops_stack.h [!AO_REAL_PTR_AS_MACRO] (AO_REAL_NEXT_PTR, AO_REAL_HEAD_PTR): Redirect to AO_real_next_ptr/AO_real_head_ptr(). * src/atomic_ops_stack.h (AO_stack_init): Move declaration down (to be after AO_stack_pop). * src/atomic_ops_stack.h (AO_real_head_ptr, AO_real_next_ptr): Declare AO_API function.
* Define AO_stack_t uniformlyIvan Maidanski2022-02-152-63/+63

* Implement AO_stack_init using memsetIvan Maidanski2022-02-141-19/+5
| | | | | | | * src/atomic_ops_stack.c (AO_stack_init): Collapse 2 definitions into single one; move the definition upper (to be outside of ifdef USE_ALMOST_LOCK_FREE); implement using memset (instead of initializing each field to 0).
* Always export stack_init/push_release/pop_acquire from atomic_ops_gplIvan Maidanski2022-02-142-40/+40
| | | | | | | | | | | | | | | | | | Previously AO_stack_init() was declared as inline, and AO_stack_push_release() and AO_stack_pop_acquire() were define as macros in case of USE_ALMOST_LOCK_FREE. Now, these 3 functions are always defined in atomic_ops_stack.c. * src/atomic_ops_stack.c [USE_ALMOST_LOCK_FREE] (AO_stack_init, AO_stack_push_release, AO_stack_pop_acquire): Implement. * src/atomic_ops_stack.c [!USE_ALMOST_LOCK_FREE] (AO_stack_init): Likewise. * src/atomic_ops_stack.h (AO_stack_init): Remove inline function definition; declare as AO_API function instead. * src/atomic_ops_stack.h [USE_ALMOST_LOCK_FREE] (AO_stack_push_release, AO_stack_pop_acquire): Declare as AO_API function instead of macro. * src/atomic_ops_stack.h (AO_stack_push, AO_HAVE_stack_push, AO_stack_pop, AO_HAVE_stack_pop): Define macro unconditionally.
* Reformat atomic_ops_stack.c/h filesIvan Maidanski2022-02-142-362/+352
| | | | | | | | | | | | | | * README_stack.txt: Place quotes properly for "popped". * src/atomic_ops_stack.c [AO_USE_ALMOST_LOCK_FREE] (AO_stack_push_explicit_aux_release, PRECHECK, AO_load_next, AO_stack_pop_explicit_aux_acquire): Reformat comments, adjust code indentation. * src/atomic_ops_stack.c [!AO_USE_ALMOST_LOCK_FREE] (ptr, AO_stack_push_release, AO_stack_pop_acquire): Likewise. * src/atomic_ops_stack.h [AO_USE_ALMOST_LOCK_FREE] (AO_BL_SIZE, AO_stack_push_explicit_aux_release): Likewise. * src/atomic_ops_stack.h: Move copyright to be the first comment in the file.

* Avoid code duplication in AO_stack_push_explicit_aux_releaseIvan Maidanski2022-02-081-19/+7
| | | | | | | | (refactoring) * src/atomic_ops_stack.c [AO_USE_ALMOST_LOCK_FREE && AO_BL_SIZE!=2] (AO_stack_push_explicit_aux_release): Remove code duplicated with AO_BL_SIZE==2 case.
