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-phminposuw.c | 57 +++++++++++++++++++++++ 1 file changed, 57 insertions(+) create mode 100644 gcc/testsuite/gcc.target/i386/sse4_1-phminposuw.c (limited to 'gcc/testsuite/gcc.target/i386/sse4_1-phminposuw.c') diff --git a/gcc/testsuite/gcc.target/i386/sse4_1-phminposuw.c b/gcc/testsuite/gcc.target/i386/sse4_1-phminposuw.c new file mode 100644 index 000000000..ab4683401 --- /dev/null +++ b/gcc/testsuite/gcc.target/i386/sse4_1-phminposuw.c @@ -0,0 +1,57 @@ +/* { 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 64 + +static void +TEST (void) +{ + union + { + __m128i x[NUM/8]; + unsigned short s[NUM]; + } src; + unsigned short minVal[NUM/8]; + int minInd[NUM/8]; + unsigned short minValScalar, minIndScalar; + int i, j, res; + + for (i = 0; i < NUM; i++) + src.s[i] = i * i / (i + i / 3.14 + 1.0); + + for (i = 0, j = 0; i < NUM; i += 8, j++) + { + res = _mm_cvtsi128_si32 (_mm_minpos_epu16 (src.x [i/8])); + minVal[j] = res & 0xffff; + minInd[j] = (res >> 16) & 0x3; + } + + for (i = 0; i < NUM; i += 8) + { + minValScalar = src.s[i]; + minIndScalar = 0; + + for (j = i + 1; j < i + 8; j++) + if (minValScalar > src.s[j]) + { + minValScalar = src.s[j]; + minIndScalar = j - i; + } + + if (minValScalar != minVal[i/8] && minIndScalar != minInd[i/8]) + abort (); + } +} -- cgit v1.2.3
