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-19.c | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) create mode 100644 gcc/testsuite/gcc.target/i386/sse-19.c (limited to 'gcc/testsuite/gcc.target/i386/sse-19.c') diff --git a/gcc/testsuite/gcc.target/i386/sse-19.c b/gcc/testsuite/gcc.target/i386/sse-19.c new file mode 100644 index 000000000..7a49a98fe --- /dev/null +++ b/gcc/testsuite/gcc.target/i386/sse-19.c @@ -0,0 +1,30 @@ +/* { dg-do compile } */ +/* { dg-skip-if "" { i?86-*-* x86_64-*-* } { "-march=*" } { "-march=x86-64" } } */ +/* { dg-options "-O3 -march=x86-64 -msse2" } */ +/* { dg-final { scan-assembler "punpcklbw" } } */ +extern void abort(); +#include +__m128i foo (char) __attribute__((noinline)); +__m128i foo (char x) { + return _mm_set1_epi8(x); +} +__m128i bar (char) __attribute__((noinline)); +__m128i bar (char x) { + return _mm_set_epi8 (x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x); +} + +main() { + int i, j; + union u { __m128i v; char c[16]; }; + union u x, y; + for (i = -128; i <= 127; i++) + { + x.v = foo ((char)i); + y.v = bar ((char)i); + for (j=0; j<16; j++) + if (x.c[j] != y.c[j]) + abort(); + } + return 0; +} + -- cgit v1.2.3
