2013-08-21Update ChangeLog fileIvan Maidanski
2013-08-17Do not use LDREXD/STREXD for Clang3.2/arm (and earlier)Ivan Maidanski
* src/atomic_ops/sysdeps/gcc/arm.h (AO_ARM_HAVE_LDREXD): Do not define for pre-Clang3.3 (since it does not allocate register pairs for LDREXD/STREXD instructions properly); add comment.
2013-08-17Fix ARM char/short fetch_and_add and double-CAS operands width (GCC/Clang)Ivan Maidanski
* src/atomic_ops/sysdeps/gcc/arm.h (AO_char_fetch_and_add, AO_short_fetch_and_add): Use 32-bit int type for "tmp" and "result" local variables instead of char/short type (resolve Clang3.3 warning "size being stored is truncated, use a modifier to specify the size" enabled by -Wasm-operand-widths compiler option); cast "incr" argument to int to prevent Clang3.2 warning about value truncation. * src/atomic_ops/sysdeps/gcc/arm.h (AO_double_compare_and_swap): Swap assembly code operands ("new_val.AO_whole" and "addr") to prevent Clang3.3 warning about operand truncation.
2013-08-17Fix ARMv7 LDREXD/STREXD double-wide operand specification (GCC/Clang)Ivan Maidanski
* src/atomic_ops/sysdeps/gcc/arm.h (AO_double_load, AO_double_store, AO_double_compare_and_swap): Specify that LDREXD and STREXD use 2 adjacent registers (thus preventing Clang3.3 from register allocation failures leading to "registers may not be the same" or "even register required" GAS errors).
2013-08-17Tests: workaround GCC 4.4.3 warning reported for list_atomic.c 'val'Ivan Maidanski
* tests/list_atomic.template (XSIZE_list_atomicXX): Use "static" modifier for "val" local variable to initialize it (cannot use direct assignment to zero because "val" type could be a SIMD vector type if XCTYPE is AO_double_t) to workaround GCC v4.4.3 "'val' is used uninitialized in this function" warning reported for AO_load.
2013-08-17Support ARMv8 target (gcc/arm)Ivan Maidanski
* src/atomic_ops/sysdeps/gcc/arm.h (__ARM_ARCH_8A__): Detect new macro (treated same as __ARM_ARCH_7A__). * src/atomic_ops/sysdeps/gcc/arm.h (AO_ARM_HAVE_SWP): Do not define for ARMv8 (since SWP{B} obsoleted); add comment. * src/atomic_ops/sysdeps/gcc/arm.h (AO_compare_and_swap): Add TODO item (for deprecated IT block containing wide Thumb instruction).
2013-08-17tests: Fix makefile sed rule for list_atomicIvan Maidanski
* tests/Makefile.am (test_atomic_include.h, list_atomic.c): Replace all occurrences of 'XX' (instead of only the first one) on every line.
2013-08-14tests: Add char/short/int/AO_double_t and dd_acquire cases to list_atomicIvan Maidanski
* tests/Makefile.am (list_atomic.c): Iterate over XSIZE/XCTYPE (in addition to XX); expand XX also as _dd_acquire_read. * tests/list_atomic.template (XSIZE_list_atomicXX): Define 'val' local variable only if used (needed for AO_double_t case).
2013-08-11tests: Add and/or/xor entries to list_atomicIvan Maidanski
* tests/list_atomic.template (list_atomicXX): Add AO_XSIZE_andXX, AO_XSIZE_orXX, AO_XSIZE_xorXX invocations.
2013-08-11tests: Parameterize list_atomic template with XSIZEIvan Maidanski
* tests/Makefile.am (list_atomic.c): Substitute XSIZE/XCTYPE for AO_t. * tests/list_atomic.template (list_atomicXX): Parameterize with XSIZE and XCTYPE (except for AO_nop and AO_test_and_set).
2013-08-11list_atomic: Add makefile rule to test list_atomic.template syntaxIvan Maidanski
* tests/Makefile.am (BUILT_SOURCES, CLEANFILES): Add "list_atomic.o". * tests/Makefile.am (list_atomic.o): New rule (to verify list_atomic.c is valid C code). * tests/list_atomic.template (list_atomicXX): Use "volatile" for "val" local variable. * tests/list_atomic.template (list_atomicXX): Define "oldval", "newval", "ts" and "incr" local variables only if used; cast string literals to void (to prevent compiler warnings). * tests/list_atomic.template (list_atomicXX): Use AO_t type for "incr" local variable instead of C long type. * tests/list_atomic.template (list_atomicXX): Define "oldval", "newval", "incr" as statitc local variables, and remove explicit initialization to zero (to void problems with initialization of these variables for AO_double_t case if the latter is a struct).
2013-08-11tests: Do not use deprecated AO_T and AO_TS_TIvan Maidanski
* tests/list_atomic.template (list_atomicXX): Use AO_t instead of deprecated AO_T. * tests/list_atomic.template (list_atomicXX): Use AO_TS_t instead of deprecated AO_TS_T. * tests/test_atomic.c (lock): Likewise.
2013-07-30Fix typo in comment of generalize-small.templateIvan Maidanski
* src/atomic_ops/generalize-arithm.template: Fix a typo in comment ("acquire"). * src/atomic_ops/generalize-arithm.h: Regenerate.
2013-05-26Add comment about store_full implementation for x86Ivan Maidanski
* src/atomic_ops/sysdeps/gcc/x86.h: Add comment about AO_store_full generalization.
2013-05-26Add non-generalized double-CAS-full implementation for AArch64Ivan Maidanski
* src/atomic_ops/sysdeps/gcc/aarch64.h (AO_double_compare_and_swap_full): New function.
2013-05-26Define AO_NO_PTHREADS in configure if no pthreads (Win32 and VxWorks)Ivan Maidanski
* configure.ac (have_pthreads): Do not define to true if check for pthread_self failed. * configure.ac (AO_NO_PTHREADS): Define if not have_pthreads.
2013-05-26Better document configure THREADDLLIBS variableIvan Maidanski
* configure.ac (THREADDLLIBS, have_pthreads): Add comments.
2013-05-26Update AUTHORSIvan Maidanski
2013-05-26Enable build using toolchain without pthreadsGilles Talis
* src/atomic_ops.c: Include pthread.h only if not AO_NO_PTHREADS (new macro). * src/atomic_ops.c (AO_pt_lock): Define only unless AO_NO_PTHREADS. * tests/test_atomic.c (main): Skip test_atomic_pthreads if both AO_NO_PTHREADS and AO_USE_PTHREAD_DEFS are defined (preventing test link failure if AO_NO_PTHREADS passed via CFLAGS).
2013-04-08Add comment about double-wide load/store on x86_64 (GCC)Ivan Maidanski
* src/atomic_ops/sysdeps/gcc/x86.h: Add comment about AO_double_load and AO_double_store implementation in 64-bit mode; remove the corresponding TODO item.
2013-04-08Fix generalized store_release_write for double-wide type on x64 (GCC)Ivan Maidanski
* src/atomic_ops/generalize-small.template (AO_XSIZE_store_release_write): Move store-write-based definition down to follow AO_XSIZE_store_write one (since AO_double_store is currently defined via CAS for gcc/x64). * src/atomic_ops/generalize-small.h: Regenerate.
2013-04-03Update AUTHORSIvan Maidanski
2013-04-03Fix AM_CONFIG_HEADER in configure for autoconf-2.69-1Manuel Serrano
* configure.ac (AM_CONFIG_HEADER): Replace obsolete macro with with AC_CONFIG_HEADERS one.
2013-03-29Generalize double_load/store for x86_64 (GCC)Ivan Maidanski
* src/atomic_ops.h (AO_GENERALIZE_TWICE): Define in case of missing double-wide load or store primitives while double-wide CAS is present (required for x86-64, at least).
2013-03-29Fix fetch_compare_and_swap asm constraints in gcc/x86.hIvan Maidanski
* src/atomic_ops/sysdeps/gcc/x86.h (AO_fetch_compare_and_swap_full): Use same asm constraints for old_val and new_val as in AO_compare_and_swap_full.
2013-03-29Reformat asm instructions of sunc/x86.hIvan Maidanski
* src/atomic_ops/sysdeps/sunc/x86.h (AO_fetch_and_add_full, AO_char_fetch_and_add_full, AO_short_fetch_and_add_full, AO_and_full, AO_or_full, AO_xor_full, AO_compare_and_swap_full): Reformat code.
2013-03-29Fix asm constraints of primitives in sunc/x86.hIvan Maidanski
* src/atomic_ops/sysdeps/sunc/x86.h (AO_fetch_and_add_full, AO_char_fetch_and_add_full, AO_short_fetch_and_add_full, AO_and_full, AO_or_full, AO_xor_full, AO_test_and_set_full, AO_compare_and_swap_full, AO_compare_double_and_swap_double_full, AO_int_fetch_and_add_full): Use "+m" asm constraint for *addr instead of "=m" (because the value pointed by addr is read and written by the code). * src/atomic_ops/sysdeps/sunc/x86.h (AO_fetch_compare_and_swap_full): Use same asm constraints and parameters order as in AO_compare_and_swap_full.
2013-03-16Merge branch 'add-aarch64-support'Ivan Maidanski
2013-03-13Fix asm constraint of CAS memory operand for gcc/alphaIvan Maidanski
* src/atomic_ops/sysdeps/gcc/alpha.h (AO_compare_and_swap): Use "+m" asm constraint for *addr instead of "=m" (because the value pointed by addr is read and written by the code).
