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.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
