From c29c36ad5d0b283404cbbaae75a4b9fb827491f2 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Wed, 18 Nov 2015 22:13:44 +0000 Subject: Add out-of-line versions of some functions (PR c/65083). PR c/65083 notes that some functions in 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 macros, along with declarations of those functions in . 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.
