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-117.c | 66 ++++++++++++++++++++++++++++++++++++ 1 file changed, 66 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/vect/vect-117.c (limited to 'gcc/testsuite/gcc.dg/vect/vect-117.c') diff --git a/gcc/testsuite/gcc.dg/vect/vect-117.c b/gcc/testsuite/gcc.dg/vect/vect-117.c new file mode 100644 index 000000000..920e29314 --- /dev/null +++ b/gcc/testsuite/gcc.dg/vect/vect-117.c @@ -0,0 +1,66 @@ +/* { dg-require-effective-target vect_int } */ + +#include +#include +#include "tree-vect.h" + +#define N 5 + +static int a[N][N] = {{ 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}}; + +static int c[N][N] = {{ 1, 2, 3, 4, 5}, + { 7, 9,11, 13,15}, + {18,21,24,27,30}, + {34,38,42,46,50}, + {55,60,65,70,75}}; + +volatile int foo; + +__attribute__ ((noinline)) +int main1 (int A[N][N], int n) +{ + + int i,j; + + /* vectorizable */ + for (i = 1; i < N; i++) + { + for (j = 0; j < n; j++) + { + A[i][j] = A[i-1][j] + A[i][j]; + } + } + + return 0; +} + +int main (void) +{ + int i,j; + + check_vect (); + + foo = 0; + main1 (a, N); + + /* check results: */ + + for (i = 0; i < N; i++) + { + for (j = 0; j < N; j++) + { + if (a[i][j] != c[i][j]) + abort(); + } + } + return 0; +} + +/* { dg-final { scan-tree-dump-times "vectorized 1 loops" 1 "vect" } } */ +/* { dg-final { scan-tree-dump-times "possible dependence between data-refs" 0 "vect" } } */ +/* { dg-final { cleanup-tree-dump "vect" } } */ + -- cgit v1.2.3
