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-105.c | 72 ++++++++++++++++++++++++++++++++++++ 1 file changed, 72 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/vect/vect-105.c (limited to 'gcc/testsuite/gcc.dg/vect/vect-105.c') diff --git a/gcc/testsuite/gcc.dg/vect/vect-105.c b/gcc/testsuite/gcc.dg/vect/vect-105.c new file mode 100644 index 000000000..bbf42af89 --- /dev/null +++ b/gcc/testsuite/gcc.dg/vect/vect-105.c @@ -0,0 +1,72 @@ +/* { dg-require-effective-target vect_int } */ + +#include +#include +#include "tree-vect.h" + +#define N 4 + +struct extraction +{ + int a[N][N]; + int b[N][N]; +}; + +static int a[N][N] = {{1,2,3,11},{4,5,6,12},{7,8,9,13},{34,45,67,83}}; +static int b[N][N] = {{17,28,15,23},{0,2,3,24},{4,31,82,25},{29,31,432,256}}; +static int c[N][N] = {{1,2,3,11},{4,9,13,34},{45,67,83,13},{34,45,67,83}}; + +volatile int y; + +__attribute__ ((noinline)) +int main1 (int x) { + int i,j; + struct extraction *p; + p = (struct extraction *) malloc (sizeof (struct extraction)); + + for (i = 0; i < N; i++) + { + for (j = 0; j < N; j++) + { + p->a[i][j] = a[i][j]; + p->b[i][j] = b[i][j]; + /* Because Y is volatile, the compiler cannot move this check out + of the loop. */ + if (y) + abort (); /* to avoid vectorization */ + } + } + + /* Vectorizable: distance > number of iterations. */ + for (i = 1; i < N; i++) + { + for (j = 0; j < N; j++) + { + *((int *)p + x + i + j) = *((int *)p + x + i + j + 5); + } + } + + /* check results: */ + for (i = 0; i < N; i++) + { + for (j = 0; j < N; j++) + { + if (p->a[i][j] != c[i][j]) + abort(); + } + } + return 0; +} + +int main (void) +{ + check_vect (); + + return main1 (N); +} + +/* { dg-final { scan-tree-dump-times "vectorized 1 loops" 1 "vect" } } */ +/* { dg-final { scan-tree-dump-times "Alignment of access forced using versioning" 2 "vect" { target vect_no_align } } } */ +/* { dg-final { scan-tree-dump-times "possible dependence between data-refs" 0 "vect" } } */ +/* { dg-final { cleanup-tree-dump "vect" } } */ + -- cgit v1.2.3
