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/sse4_1-pmaxsb.c | 46 +++++++++++++++++++++++++++ 1 file changed, 46 insertions(+) create mode 100644 gcc/testsuite/gcc.target/i386/sse4_1-pmaxsb.c (limited to 'gcc/testsuite/gcc.target/i386/sse4_1-pmaxsb.c') diff --git a/gcc/testsuite/gcc.target/i386/sse4_1-pmaxsb.c b/gcc/testsuite/gcc.target/i386/sse4_1-pmaxsb.c new file mode 100644 index 000000000..ab445eefd --- /dev/null +++ b/gcc/testsuite/gcc.target/i386/sse4_1-pmaxsb.c @@ -0,0 +1,46 @@ +/* { dg-do run } */ +/* { dg-require-effective-target sse4 } */ +/* { dg-options "-O2 -msse4.1" } */ + +#ifndef CHECK_H +#define CHECK_H "sse4_1-check.h" +#endif + +#ifndef TEST +#define TEST sse4_1_test +#endif + +#include CHECK_H + +#include + +#define NUM 1024 + +static void +TEST (void) +{ + union + { + __m128i x[NUM / 16]; + char i[NUM]; + } dst, src1, src2; + int i, sign = 1; + char max; + + for (i = 0; i < NUM; i++) + { + src1.i[i] = i * i * sign; + src2.i[i] = (i + 20) * sign; + sign = -sign; + } + + for (i = 0; i < NUM; i += 16) + dst.x[i / 16] = _mm_max_epi8 (src1.x[i / 16], src2.x[i / 16]); + + for (i = 0; i < NUM; i++) + { + max = src1.i[i] <= src2.i[i] ? src2.i[i] : src1.i[i]; + if (max != dst.i[i]) + abort (); + } +} -- cgit v1.2.3
