2016-04-20Don't build 32-bit libatomic with -march=i486 on x86-64H.J. Lu2-8/+8
Gcc uses the same -march= for both -m32 and -m64 on x86-64 unless --with-arch-32= is used. There is no need for -march=i486 to compile 32-bit libatomic on x86-64. PR target/70454 * configure.tgt (XCFLAGS): Don't add -march=i486 to compile 32-bit x86 target library on x86-64. From-SVN: r235287
2016-01-06Fix libatomic multilib parallel build (PR other/67627)Szabolcs Nagy3-6/+20
The all-multi target may be built in parallel with the %_.lo targets which generate make dependencies that are parsed during the build of all-multi. This patch forces all-multi to only run after the *_.lo targets are done. libatomic: PR other/67627 * Makefile.am (all-multi): Add dependency. * Makefile.in: Regenerate. From-SVN: r232102

2015-11-18Add out-of-line versions of some <stdatomic.h> functions (PR c/65083).Joseph Myers8-6/+136
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.

2015-10-09Testsuite: add dg-{begin|end}-multiline-output commandsDavid Malcolm2-0/+6
This patch adds an easy way to write tests for expected multiline output. For example we can test carets and underlines for a particular diagnostic with: /* { dg-begin-multiline-output "" } typedef struct _GMutex GMutex; ^~~~~~~ { dg-end-multiline-output "" } */ multiline.exp is used by prune.exp; hence we need to load it before prune.exp via *load_gcc_lib* for the testsuites of the various non-"gcc" support libraries (e.g. boehm-gc). gcc/testsuite/ChangeLog: * lib/multiline.exp: New file. * lib/prune.exp: Load multiline.exp.

2013-03-24Avoid non constant memory model uses in libatomicAndi Kleen4-4/+4
x86 ends up using non constant memory models for some of the libatomic functions. These all end up as __ATOMIC_SEQ_CST. Just use this directly. This avoids a new warning for non constant memory models, which broke the bootstrap with -Werror Passed bootstrap and test on x86_64-linux. libatomic/: 2013-03-23 Andi Kleen <ak@linux.intel.com> * gcas.c: (EXACT_INLINE): Use __ATOMIC_SEQ_CST. * gexch.c: (EXACT_INLINE): Use __ATOMIC_SEQ_CST. * gload.c: (EXACT_INLINE): Use __ATOMIC_SEQ_CST. * gstore.c: (EXACT_INLINE): Use __ATOMIC_SEQ_CST. diff --git a/libatomic/gcas.c b/libatomic/gcas.c index edbf611..e3d77f3 100644 --- a/libatomic/gcas.c +++ b/libatomic/gcas.c @@ -32,7 +32,7 @@ # define EXACT_INLINE(N) \ if (C2(HAVE_ATOMIC_CAS_,N)) \ return __atomic_compare_exchange_n \ - (PTR(N,mptr), PTR(N,eptr), *PTR(N,dptr), false, smodel, fmodel) + (PTR(N,mptr), PTR(N,eptr), *PTR(N,dptr), false, __ATOMIC_SEQ_CST, __ATOMIC_SEQ_CST) #else # define EXACT_INLINE(N) #endif diff --git a/libatomic/gexch.c b/libatomic/gexch.c index 1999067..c8c8658 100644 --- a/libatomic/gexch.c +++ b/libatomic/gexch.c @@ -33,7 +33,7 @@ if (C2(HAVE_ATOMIC_EXCHANGE_,N)) \ { \ *PTR(N,rptr) = __atomic_exchange_n \ - (PTR(N,mptr), *PTR(N,vptr), smodel); \ + (PTR(N,mptr), *PTR(N,vptr), __ATOMIC_SEQ_CST); \ return; \ } #else diff --git a/libatomic/gload.c b/libatomic/gload.c index df318d5..85865bd 100644 --- a/libatomic/gload.c +++ b/libatomic/gload.c @@ -32,7 +32,7 @@ # define EXACT_INLINE(N, DEST, SRC, DONE) \ if (C2(HAVE_ATOMIC_LDST_,N)) \ { \ - DEST = __atomic_load_n (SRC, smodel); \ + DEST = __atomic_load_n (SRC, __ATOMIC_SEQ_CST); \ DONE; \ } #else diff --git a/libatomic/gstore.c b/libatomic/gstore.c index d571e58..84f9a8d 100644 --- a/libatomic/gstore.c +++ b/libatomic/gstore.c @@ -32,7 +32,7 @@ # define EXACT_INLINE(N) \ if (C2(HAVE_ATOMIC_LDST_,N)) \ { \ - __atomic_store_n (PTR(N,mptr), *PTR(N,vptr), smodel); \ + __atomic_store_n (PTR(N,mptr), *PTR(N,vptr), __ATOMIC_SEQ_CST); \ return; \ } #else From-SVN: r197017
