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-87.c | 56 +++++++++++++++++++++++++++++++++++++ 1 file changed, 56 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/vect/vect-87.c (limited to 'gcc/testsuite/gcc.dg/vect/vect-87.c') diff --git a/gcc/testsuite/gcc.dg/vect/vect-87.c b/gcc/testsuite/gcc.dg/vect/vect-87.c new file mode 100644 index 000000000..9912f19e7 --- /dev/null +++ b/gcc/testsuite/gcc.dg/vect/vect-87.c @@ -0,0 +1,56 @@ +/* { dg-require-effective-target vect_int } */ + +#include +#include "tree-vect.h" + +#define N 16 + +__attribute__ ((noinline)) +int main1 (int n, int *a) +{ + int i, j, k; + int b[N]; + + for (i = 0; i < n; i++) + { + for (j = 0; j < n; j++) + { + k = i + n; + a[j] = k; + } + b[i] = k; + } + + + for (j = 0; j < n; j++) + if (a[j] != i + n - 1) + abort(); + + for (j = 0; j < n; j++) + if (b[j] != j + n) + abort(); + + return 0; +} + +int main (void) +{ + int a[N] __attribute__ ((__aligned__(__BIGGEST_ALIGNMENT__))); + + check_vect (); + + main1 (N, a); + main1 (0, a); + main1 (1, a); + main1 (2, a); + main1 (N-1, a); + + return 0; +} + +/* Fails for targets that don't vectorize PLUS (e.g alpha). */ +/* { dg-final { scan-tree-dump-times "vectorized 1 loops" 1 "vect" } } */ +/* { dg-final { scan-tree-dump-times "Vectorizing an unaligned access" 0 "vect" } } */ +/* { dg-final { scan-tree-dump-times "Alignment of access forced using peeling" 1 "vect" {target vector_alignment_reachable} } } */ +/* { dg-final { scan-tree-dump-times "Alignment of access forced using versioning" 1 "vect" {target { {! vector_alignment_reachable} && {! vect_hw_misalign} } } } } */ +/* { dg-final { cleanup-tree-dump "vect" } } */ -- cgit v1.2.3
