| | | | | * src/atomic_ops/sysdeps/gcc/x86.h (AO_USE_PENTIUM4_INSTRS): Define if __SSE2__ is defined; update comment (and remove TODO item).
* Fix assembly comment prefix and identify memory clobbers for AArch64Yvan Roux2013-03-091-44/+35
| | | | | | | | | | | | | | * src/atomic_ops/sysdeps/gcc/aarch64.h: Revert comments beginning marker to '//' (since '@' is not supported for A64 assembler). * src/atomic_ops/sysdeps/gcc/aarch64.h (AO_double_load): Add comment about the need for STXP instruction; remove TODO item. * src/atomic_ops/sysdeps/gcc/aarch64.h (AO_double_store): Add comment about absence of "cc" in clobber lists; remove TODO item. * src/atomic_ops/sysdeps/gcc/aarch64.h (AO_double_load, AO_double_load_acquire, AO_double_store, AO_double_store_release, AO_double_compare_and_swap, AO_double_compare_and_swap_acquire, AO_double_compare_and_swap_release): Use Q constraint (instead of "r") for 'addr' argument to instruct the compiler about memory clobbers.
* Use AO_EXPECT_FALSE for AArch64 double_load/storeIvan Maidanski2013-03-051-14/+20
| | | | | | | | | | * src/atomic_ops/sysdeps/gcc/aarch64.h (AO_HAVE_DOUBLE_PTR_STORAGE): Do not check (since defined in standard_ao_double_t.h for AArch64). * src/atomic_ops/sysdeps/gcc/aarch64.h (AO_double_load): Add TODO items. * src/atomic_ops/sysdeps/gcc/aarch64.h (AO_double_load, AO_double_load_acquire, AO_double_store, AO_double_store_release): Use AO_EXPECT_FALSE.

| | | | | | | | | | | | * src/atomic_ops/sysdeps/gcc/aarch64.h (AO_double_load, AO_double_load_acquire, AO_double_store, AO_double_store_release, AO_double_compare_and_swap, AO_double_compare_and_swap_acquire, AO_double_compare_and_swap_release): Define using inline assembly (because GCC 4.7-2013.01 has no support of 16-byte atomic operations). * src/atomic_ops/sysdeps/gcc/generic.h (AO_double_load, AO_double_load_acquire, AO_double_store, AO_double_store_release, AO_double_compare_and_swap): Do not define if the corresponding AO_HAVE_double_X macro is defined.

| * Remove improper comment for AO_XSIZE_load_readIvan Maidanski2013-02-282-18/+6
| | | | | | | | | | | | | | | | | | | | * src/atomic_ops/generalize-small.template (AO_XSIZE_load_read): Remove improper comment (because nop barrier type matches that of load primitive). * src/atomic_ops/generalize-small.template (AO_XSIZE_store_write): Reorder AO_HAVE_nop_write and AO_HAVE_XSIZE_store checking (to match that for other primitives in this file). * src/atomic_ops/generalize-small.h: Regenerate.
| * Implement AO_and/or/xor efficiently for ARMIvan Maidanski2013-02-141-0/+57
| | | | | | | | | | * src/atomic_ops/sysdeps/gcc/arm.h (AO_and, AO_or, AO_xor): Implement directly using LDREX/STREX (enabled only if not AO_PREFER_GENERALIZED).
| * Add compile-time assertion for size of 'standard' AO_double_tIvan Maidanski2013-02-141-0/+5

| * Fix (remove) invalid include of read_ordered.h for ARMIvan Maidanski2013-02-143-5/+1
| | | | | | | | | | | | | | | | | | | | | | | | (fix commit 2df9c1e partially) * src/atomic_ops/sysdeps/gcc/arm.h: Do not include read_ordered.h (because load_acquire should contain a DMB instruction in a multi-core case, new load_acquire/read primitives implementation is generalized using nop_full/read which either contain a DMB instruction, or is just a compiler barrier for uniprocessor). * src/atomic_ops/sysdeps/armcc/arm_v6.h: Likewise. * src/atomic_ops/sysdeps/msftc/arm.h: Likewise.
| * Revert "Fix read_ordered.h inclusion for ARM"Ivan Maidanski2013-02-143-7/+5
| | | | | | | | | | | | (because it makes load_acquire/read incorrect for multi-core ARM) This reverts commit fcc838be49c98486c26738764f895d34de0716be.

| | | | | | | | | | | | | | | | | | | | | | | | * src/atomic_ops/sysdeps/msftc/arm.h: Include all_aligned_atomic_load_store.h instead of all_atomic_load_store.h (since unaligned accesses are not guaranteed to be atomic). * src/atomic_ops/sysdeps/msftc/arm.h (AO_load): Remove; include all_aligned_atomic_load_store.h unconditionally instead (thus implementing AO[_char/short]_load/store via simple LDR/STR; add comment about Windows interrupt handlers. * src/atomic_ops/sysdeps/msftc/arm.h: Add TODO item to implement AO_test_and_set_full (for pre-ARMv6).
| * Define AO_nop_full as compiler barrier for pre-ARMv6 single-core caseIvan Maidanski2013-02-142-60/+60

| | | | | | | | | | | | | | | | * src/atomic_ops/sysdeps/gcc/aarch64.h (AO_nop_write): Define via asm (dmb st) statement unless AO_UNIPROCESSOR (because it seems there is no equivalent definition using compiler __atomic_thread_fence). * src/atomic_ops/sysdeps/gcc/generic.h (AO_nop_write): Do not define if already is.

| | | | | | | | | | | | | | | | | | | | | | | | | | | * src/atomic_ops/sysdeps/ao_t_is_int.template: Update comment; remove TODO item. * src/atomic_ops/sysdeps/ao_t_is_int.template (AO_int_and_XBAR, AO_int_or_XBAR, AO_int_xor_XBAR): Define template primitive (and define the corresponding AO_HAVE_int_X macro). * src/atomic_ops/sysdeps/ao_t_is_int.h: Regenerate.
| | * Generate ao_t_is_int header from templateIvan Maidanski2013-01-143-96/+489
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/Makefile.am (EXTRA_DIST): Add ao_t_is_int.template entry. * src/Makefile.am (BUILT_SOURCES): Add ao_t_is_int.h entry. * src/Makefile.am (nobase_private_HEADERS): Remove ao_t_is_int.h entry (since added to BUILT_SOURCES). * src/Makefile.am (atomic_ops/sysdeps/ao_t_is_int.h): New rule (to generate the header from ao_t_is_int.template substituting XBAR parameter with the corresponding barrier type). * src/atomic_ops/sysdeps/ao_t_is_int.h: Regenerate.
| | * Fix a typo in ao_t_is_int.h commentIvan Maidanski2013-01-141-1/+1
| | | | | | | | | | | | * src/atomic_ops/sysdeps/ao_t_is_int.h: Fix a typo in comment.
| | * Fix return type of AO_int_X primitives defined in ao_t_is_int headerIvan Maidanski2013-01-131-18/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/atomic_ops/sysdeps/ao_t_is_int.h (AO_int_fetch_compare_and_swap_full, AO_int_fetch_compare_and_swap_acquire, AO_int_fetch_compare_and_swap_release, AO_int_fetch_compare_and_swap_write, AO_int_fetch_compare_and_swap_read, AO_int_fetch_compare_and_swap, AO_int_load_acquire, AO_int_fetch_and_add_full, AO_int_fetch_and_add1_acquire, AO_int_fetch_and_add1_release, AO_int_fetch_and_sub1_acquire, AO_int_fetch_and_sub1_release): Cast result to unsigned int instead of signed int.
| | * Fix ordered_except_wr header inclusion for s390Ivan Maidanski2013-01-131-1/+2
| | | | | | | | | | | | | | | | | | | | | * src/atomic_ops/sysdeps/gcc/s390.h: Move include of ordered_except_wr.h down to be after all_aligned_atomic_load_store.h inclusion (since the latter defines AO_X_load/store primitives used by the former header).
| | * Fix read_ordered.h inclusion for ARMIvan Maidanski2013-01-133-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | * src/atomic_ops/sysdeps/armcc/arm_v6.h: Move include of read_ordered.h down to the end of the file to be after AO_load/store definition (since read_ordered.h depends on these primitives). * src/atomic_ops/sysdeps/gcc/arm.h: Likewise. * src/atomic_ops/sysdeps/msftc/arm.h: Likewise.
| | * Remove AO_store_full from msftc/arm.h in favor of generalized primitiveIvan Maidanski2013-01-131-19/+2
| | | | | | | | | | | | | | | | | | | | | | | | (code refactoring) * src/atomic_ops/sysdeps/msftc/arm.h (AO_store_full): Remove since similar definition exists in generalize-small.h. * src/atomic_ops/sysdeps/msftc/arm.h: Add TODO item for AO_store().
