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-nest-cycle-2.c | 47 +++++++++++++++++++++++++++ 1 file changed, 47 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/vect/vect-nest-cycle-2.c (limited to 'gcc/testsuite/gcc.dg/vect/vect-nest-cycle-2.c') diff --git a/gcc/testsuite/gcc.dg/vect/vect-nest-cycle-2.c b/gcc/testsuite/gcc.dg/vect/vect-nest-cycle-2.c new file mode 100644 index 000000000..22b1d98de --- /dev/null +++ b/gcc/testsuite/gcc.dg/vect/vect-nest-cycle-2.c @@ -0,0 +1,47 @@ +/* { dg-require-effective-target vect_float } */ + +#include +#include "tree-vect.h" + +#define N 16 + +float out[N]; +float check_res[N] = {880,864,848,832,816,800,784,768,752,736,720,704,688,672,656,640}; +float a[2*N] = {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31}; + +/* Outer-loop vectorization. */ + +__attribute__ ((noinline)) void +foo () +{ + int i, j; + float res; + + for (i = 0; i < N; i++) + { + res = 1000; + + for (j = 0; j < N; j++) + res = res - a[i+j]; + + out[i] = res; + } + + for (i = 0; i < N; i++) + if (out[i] != check_res[i]) + abort (); + +} + +int main () +{ + check_vect (); + + foo(); + + return 0; +} + +/* { dg-final { scan-tree-dump-times "OUTER LOOP VECTORIZED" 1 "vect" { xfail vect_no_align } } } */ +/* { dg-final { cleanup-tree-dump "vect" } } */ + -- cgit v1.2.3
