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.target/i386/avx-vperm2f128-256-2.c | 39 ++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 gcc/testsuite/gcc.target/i386/avx-vperm2f128-256-2.c (limited to 'gcc/testsuite/gcc.target/i386/avx-vperm2f128-256-2.c') diff --git a/gcc/testsuite/gcc.target/i386/avx-vperm2f128-256-2.c b/gcc/testsuite/gcc.target/i386/avx-vperm2f128-256-2.c new file mode 100644 index 000000000..db9c65bce --- /dev/null +++ b/gcc/testsuite/gcc.target/i386/avx-vperm2f128-256-2.c @@ -0,0 +1,39 @@ +/* { dg-do run } */ +/* { dg-require-effective-target avx } */ +/* { dg-options "-O2 -mavx" } */ + +#include "avx-check.h" + +#ifndef IMM8 +# define IMM8 99 +#endif + + +void static +avx_test () +{ + union256d source1, source2, u; + double s1[4]={1, 2, 3, 4}; + double s2[4]={5, 6, 7, 8}; + double e[4]; + + source1.x = _mm256_loadu_pd(s1); + source2.x = _mm256_loadu_pd(s2); + u.x = _mm256_permute2f128_pd(source1.x, source2.x, IMM8); + + if(IMM8 & 8) e[0] = e[1] = 0; + else{ + e[0] = (IMM8 & 2 ? s2 : s1)[(IMM8 & 1) * 2]; + e[1] = (IMM8 & 2 ? s2 : s1)[(IMM8 & 1) * 2 + 1]; + } + if(IMM8 & 128) e[3] = e[3] = 0; + else{ + unsigned m = (IMM8 >> 4) & 3; + e[2] = (m & 2 ? s2 : s1)[(m & 1) * 2]; + e[3] = (m & 2 ? s2 : s1)[(m & 1) * 2 + 1]; + } + + if (check_union256d (u, e)) + abort (); +} + -- cgit v1.2.3
