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.dg/vect/pr37539.c | 47 +++++++++++++++++++++++++++++++++++++ 1 file changed, 47 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/vect/pr37539.c (limited to 'gcc/testsuite/gcc.dg/vect/pr37539.c') diff --git a/gcc/testsuite/gcc.dg/vect/pr37539.c b/gcc/testsuite/gcc.dg/vect/pr37539.c new file mode 100644 index 000000000..1e73425de --- /dev/null +++ b/gcc/testsuite/gcc.dg/vect/pr37539.c @@ -0,0 +1,47 @@ +/* { dg-require-effective-target vect_int } */ + +#include +#include "tree-vect.h" + +__attribute__ ((noinline)) void +ayuv2yuyv_ref (int *d, int *src, int n) +{ + char *dest = (char *)d; + int i; + + for(i=0;i>16; + dest[i*4 + 1] = (src[i*2 + 1])>>8; + dest[i*4 + 2] = (src[i*2 + 0])>>16; + dest[i*4 + 3] = (src[i*2 + 0])>>0; + } + + /* Check results. */ + for(i=0;i>16 + || dest[i*4 + 1] != (src[i*2 + 1])>>8 + || dest[i*4 + 2] != (src[i*2 + 0])>>16 + || dest[i*4 + 3] != (src[i*2 + 0])>>0) + abort(); + } +} + +int main () +{ + int d[256], src[128], i; + + check_vect (); + + for (i = 0; i < 128; i++) + src[i] = i; + + ayuv2yuyv_ref(d, src, 128); + + return 0; +} + +/* { dg-final { scan-tree-dump-times "vectorized 1 loops" 2 "vect" { target vect_strided_wide } } } */ +/* { dg-final { cleanup-tree-dump "vect" } } */ + + + -- cgit v1.2.3
