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/ssse3-pmulhrsw.c | 85 ++++++++++++++++++++++++++ 1 file changed, 85 insertions(+) create mode 100644 gcc/testsuite/gcc.target/i386/ssse3-pmulhrsw.c (limited to 'gcc/testsuite/gcc.target/i386/ssse3-pmulhrsw.c') diff --git a/gcc/testsuite/gcc.target/i386/ssse3-pmulhrsw.c b/gcc/testsuite/gcc.target/i386/ssse3-pmulhrsw.c new file mode 100644 index 000000000..24570b3bd --- /dev/null +++ b/gcc/testsuite/gcc.target/i386/ssse3-pmulhrsw.c @@ -0,0 +1,85 @@ +/* { dg-do run } */ +/* { dg-require-effective-target ssse3 } */ +/* { dg-options "-O2 -fno-strict-aliasing -mssse3" } */ + +#ifndef CHECK_H +#define CHECK_H "ssse3-check.h" +#endif + +#ifndef TEST +#define TEST ssse3_test +#endif + +#include CHECK_H + +#include "ssse3-vals.h" + +#include + +#ifndef __AVX__ +/* Test the 64-bit form */ +static void +ssse3_test_pmulhrsw (int *i1, int *i2, int *r) +{ + __m64 t1 = *(__m64 *) i1; + __m64 t2 = *(__m64 *) i2; + *(__m64 *) r = _mm_mulhrs_pi16 (t1, t2); + _mm_empty (); +} +#endif + +/* Test the 128-bit form */ +static void +ssse3_test_pmulhrsw128 (int *i1, int *i2, int *r) +{ + /* Assumes incoming pointers are 16-byte aligned */ + __m128i t1 = *(__m128i *) i1; + __m128i t2 = *(__m128i *) i2; + *(__m128i *) r = _mm_mulhrs_epi16 (t1, t2); +} + +/* Routine to manually compute the results */ +static void +compute_correct_result (int *i1, int *i2, int *r) +{ + short *s1 = (short *) i1; + short *s2 = (short *) i2; + short *sout = (short *) r; + int t0; + int i; + + for (i = 0; i < 8; i++) + { + t0 = (((int) s1[i] * (int) s2[i]) >> 14) + 1; + sout[i] = (short) (t0 >> 1); + } +} + +static void +TEST (void) +{ + int i; + int r [4] __attribute__ ((aligned(16))); + int ck [4]; + int fail = 0; + + for (i = 0; i < 256; i += 8) + { + /* Manually compute the result */ + compute_correct_result (&vals[i + 0], &vals[i + 4], ck); + +#ifndef __AVX__ + /* Run the 64-bit tests */ + ssse3_test_pmulhrsw (&vals[i + 0], &vals[i + 4], &r[0]); + ssse3_test_pmulhrsw (&vals[i + 2], &vals[i + 6], &r[2]); + fail += chk_128 (ck, r); +#endif + + /* Run the 128-bit tests */ + ssse3_test_pmulhrsw128 (&vals[i + 0], &vals[i + 4], r); + fail += chk_128 (ck, r); + } + + if (fail != 0) + abort (); +} -- cgit v1.2.3
