2024-06-12Libatomic: Define per-file identifier macrosVictor Do Nascimento1-0/+2
In order to facilitate the fine-tuning of how `libatomic_i.h' and `host-config.h' headers are used by different atomic functions, we define distinct identifier macros for each file which, in implementing atomic operations, imports these headers. The idea is that different parts of these headers could then be conditionally defined depending on the macros set by the file that `#include'd them. Given how it is possible that some file names are generic enough that using them as-is for macro names (e.g. flag.c -> FLAG) may potentially lead to name clashes with other macros, all file names first have LAT_ prepended to them such that, for example, flag.c is assigned the LAT_FLAG macro. Libatomic/ChangeLog: * cas_n.c (LAT_CAS_N): New. * exch_n.c (LAT_EXCH_N): Likewise. * fadd_n.c (LAT_FADD_N): Likewise. * fand_n.c (LAT_FAND_N): Likewise. * fence.c (LAT_FENCE): Likewise. * fenv.c (LAT_FENV): Likewise. * fior_n.c (LAT_FIOR_N): Likewise. * flag.c (LAT_FLAG): Likewise. * fnand_n.c (LAT_FNAND_N): Likewise. * fop_n.c (LAT_FOP_N): Likewise * fsub_n.c (LAT_FSUB_N): Likewise. * fxor_n.c (LAT_FXOR_N): Likewise. * gcas.c (LAT_GCAS): Likewise. * gexch.c (LAT_GEXCH): Likewise. * glfree.c (LAT_GLFREE): Likewise. * gload.c (LAT_GLOAD): Likewise. * gstore.c (LAT_GSTORE): Likewise. * load_n.c (LAT_LOAD_N): Likewise. * store_n.c (LAT_STORE_N): Likewise. * tas_n.c (LAT_TAS_N): Likewise.

2015-11-18Add out-of-line versions of some <stdatomic.h> functions (PR c/65083).Joseph Myers1-0/+64
PR c/65083 notes that some functions in <stdatomic.h> are normal functions, not generic functions, and so need to have out-of-line copies that can be called when macro expansion is suppressed (unlike the generic functions where DR#419 makes it undefined if you suppress a macro expansion). This patch adds such out-of-line definitions in libatomic for those six functions, at a new LIBATOMIC_1.2 symbol version, as trivial wrappers to the <stdatomic.h> macros, along with declarations of those functions in <stdatomic.h>. Tests are added that are based on the corresponding tests for the macros, but with parentheses around the function names to force the out-of-line functions to be used. Bootstrapped with no regressions on x86_64-pc-linux-gnu. gcc: * ginclude/stdatomic.h (atomic_thread_fence, atomic_signal_fence) (atomic_flag_test_and_set, atomic_flag_test_and_set_explicit) (atomic_flag_clear, atomic_flag_clear_explicit): Declare as functions before defining as macros. gcc/testsuite: * gcc.dg/atomic/stdatomic-fence-2.c, gcc.dg/atomic/stdatomic-flag-2.c: New tests. libatomic: * fence.c, flag.c: New files. * Makefile.am (libatomic_la_SOURCES): Add fence.c and flag.c. * Makefile.in: Regenerate. * configure.ac (libtool_VERSION): Change to 3:0:2. * configure: Regenerate. * libatomic.map (LIBATOMIC_1.2): New symbol version.
