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/vect-outer-4l.c | 69 +++++++++++++++++++++++++++++++ 1 file changed, 69 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/vect/vect-outer-4l.c (limited to 'gcc/testsuite/gcc.dg/vect/vect-outer-4l.c') diff --git a/gcc/testsuite/gcc.dg/vect/vect-outer-4l.c b/gcc/testsuite/gcc.dg/vect/vect-outer-4l.c new file mode 100644 index 000000000..c6cc4a8d1 --- /dev/null +++ b/gcc/testsuite/gcc.dg/vect/vect-outer-4l.c @@ -0,0 +1,69 @@ +/* { dg-require-effective-target vect_int } */ +#include +#include "tree-vect.h" + +#define N 96 +#define M 128 +unsigned short in[N+M]; +unsigned int out[N]; +unsigned char arr[N]; + +/* Outer-loop vectorization. */ +/* Not vectorized due to multiple-types in the inner-loop. */ + +__attribute__ ((noinline)) unsigned int +foo (){ + int i,j; + unsigned int diff; + unsigned int s=0; + + for (i = 0; i < N; i++) { + arr[i] = 3; + diff = 0; + for (j = 0; j < M; j+=8) { + diff += in[j+i]; + } + s+=diff; + } + return s; +} + +__attribute__ ((noinline)) unsigned int +bar (int i, unsigned int diff, unsigned short *in) +{ + int j; + for (j = 0; j < M; j+=8) { + diff += in[j+i]; + } + return diff; +} + +int main (void) +{ + int i, j; + unsigned int diff; + unsigned int s=0,sum=0; + + check_vect (); + + for (i = 0; i < N+M; i++) { + in[i] = i; + } + + sum=foo (); + + for (i = 0; i < N; i++) { + arr[i] = 3; + diff = 0; + diff = bar (i, diff, in); + s += diff; + } + + if (s != sum) + abort (); + + return 0; +} + +/* { dg-final { scan-tree-dump-times "OUTER LOOP VECTORIZED" 1 "vect" { xfail *-*-* } } } */ +/* { dg-final { cleanup-tree-dump "vect" } } */ -- cgit v1.2.3
