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.dg/torture/pr40470-1.c | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/torture/pr40470-1.c (limited to 'gcc/testsuite/gcc.dg/torture/pr40470-1.c') diff --git a/gcc/testsuite/gcc.dg/torture/pr40470-1.c b/gcc/testsuite/gcc.dg/torture/pr40470-1.c new file mode 100644 index 000000000..cb2510e88 --- /dev/null +++ b/gcc/testsuite/gcc.dg/torture/pr40470-1.c @@ -0,0 +1,22 @@ +/* { dg-do compile { target i?86-*-* x86_64-*-* } } */ +/* { dg-options "-msse4" } */ +#include +__m128i load (char *); +char * +foo (char *p1, char *p2, + int bmsk, __m128i mask1, __m128i mask2) +{ + int len = 0; + __m128i frag1, frag2; + int cmp_s; + if( !p2[0]) return p1; + if( !p1[0] ) return NULL; + frag2 = load (p2); + frag1 = load (p1); + frag2 = _mm_blendv_epi8(frag2, mask2, mask1); + frag1 = _mm_blendv_epi8(frag1, mask2, mask1); + cmp_s = _mm_cmpistrs(frag2, frag1, 0x0c); + if( cmp_s ) + __asm("bsfl %[bmsk], %[len]" : [len] "=r" (len) : [bmsk] "r" (bmsk) ); + return p1 + len; +} -- cgit v1.2.3
