Add out-of-line versions of some <stdatomic.h> functions (PR c/65083).
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.
