From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- libgomp/testsuite/libgomp.c/atomic-2.c | 37 ++++++++++++++++++++++++++++++++++ 1 file changed, 37 insertions(+) create mode 100644 libgomp/testsuite/libgomp.c/atomic-2.c (limited to 'libgomp/testsuite/libgomp.c/atomic-2.c') diff --git a/libgomp/testsuite/libgomp.c/atomic-2.c b/libgomp/testsuite/libgomp.c/atomic-2.c new file mode 100644 index 000000000..c8779483b --- /dev/null +++ b/libgomp/testsuite/libgomp.c/atomic-2.c @@ -0,0 +1,37 @@ +/* { dg-do run } */ +/* { dg-options "-O2 -mcx16" { target { { i?86-*-* x86_64-*-* } && lp64 } } } */ + +#ifdef __x86_64__ +#include "cpuid.h" +#endif + +double d = 1.5; +long double ld = 3; +extern void abort (void); + +void +test (void) +{ +#pragma omp atomic + d *= 1.25; +#pragma omp atomic + ld /= 0.75; + if (d != 1.875 || ld != 4.0L) + abort (); +} + +int +main (void) +{ +#ifdef __x86_64__ + unsigned int eax, ebx, ecx, edx; + + if (!__get_cpuid (1, &eax, &ebx, &ecx, &edx)) + return 0; + + if (!(ecx & bit_CMPXCHG16B)) + return 0; +#endif + test (); + return 0; +} -- cgit v1.2.3
