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/sse-1.c | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) create mode 100644 gcc/testsuite/gcc.target/i386/sse-1.c (limited to 'gcc/testsuite/gcc.target/i386/sse-1.c') diff --git a/gcc/testsuite/gcc.target/i386/sse-1.c b/gcc/testsuite/gcc.target/i386/sse-1.c new file mode 100644 index 000000000..afae22d37 --- /dev/null +++ b/gcc/testsuite/gcc.target/i386/sse-1.c @@ -0,0 +1,25 @@ +/* PR 12902 */ +/* { dg-do compile } */ +/* { dg-options "-O1 -msse" } */ + +#include + +typedef union +{ + int i[4]; + float f[4]; + __m128 v; +} vector4_t; + +void +swizzle (const void *a, vector4_t * b, vector4_t * c) +{ + b->v = _mm_loadl_pi (b->v, (__m64 *) a); + c->v = _mm_loadl_pi (c->v, ((__m64 *) a) + 1); +} + +/* While one legal rendering of each statement would be movaps;movlps;movaps, + we can implmenent this with just movlps;movlps.
