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. --- gcc/testsuite/gcc.target/i386/pr52736.c | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100644 gcc/testsuite/gcc.target/i386/pr52736.c (limited to 'gcc/testsuite/gcc.target/i386/pr52736.c') diff --git a/gcc/testsuite/gcc.target/i386/pr52736.c b/gcc/testsuite/gcc.target/i386/pr52736.c new file mode 100644 index 000000000..f35c1fd6c --- /dev/null +++ b/gcc/testsuite/gcc.target/i386/pr52736.c @@ -0,0 +1,29 @@ +/* PR target/52736 */ +/* { dg-do run } */ +/* { dg-options "-O1 -msse2" } */ +/* { dg-require-effective-target sse2_runtime } */ + +#include + +typedef double D __attribute__((may_alias)); +__attribute__((aligned(16))) static const double r[4] = { 1., 5., 1., 3. }; + +__attribute__((noinline, noclone)) +void +foo (int x) +{ + asm volatile ("" : "+g" (x) : : "memory"); + if (x != 3) + __builtin_abort (); +} + +int +main () +{ + __m128d t = _mm_set1_pd (5.); + ((D *)(&t))[0] = 1.; + foo (_mm_movemask_pd (_mm_cmpeq_pd (t, _mm_load_pd (&r[0])))); + ((D *)(&t))[1] = 3.; + foo (_mm_movemask_pd (_mm_cmpeq_pd (t, _mm_load_pd (&r[2])))); + return 0; +} -- cgit v1.2.3
