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-iv-1.c | 42 +++++++++++++++++++++++++++++++++++ 1 file changed, 42 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/vect/vect-iv-1.c (limited to 'gcc/testsuite/gcc.dg/vect/vect-iv-1.c') diff --git a/gcc/testsuite/gcc.dg/vect/vect-iv-1.c b/gcc/testsuite/gcc.dg/vect/vect-iv-1.c new file mode 100644 index 000000000..5d6ab5cd2 --- /dev/null +++ b/gcc/testsuite/gcc.dg/vect/vect-iv-1.c @@ -0,0 +1,42 @@ +/* { dg-require-effective-target vect_int } */ + +#include +#include "tree-vect.h" + +#define N 16 +int result[N] = {8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38}; + +__attribute__ ((noinline)) int main1 (int X) +{ + int arr[N]; + int k = X; + int m, i=0; + + /* vectorization of induction. */ + + do { + m = k + 5; + arr[i] = m; + k = k + 2; + i++; + } while (i < N); + + /* check results: */ + for (i = 0; i < N; i++) + { + if (arr[i] != result[i]) + abort (); + } + + return 0; +} + +int main (void) +{ + check_vect (); + + return main1 (3); +} + +/* { dg-final { scan-tree-dump-times "vectorized 1 loops" 1 "vect" } } */ +/* { dg-final { cleanup-tree-dump "vect" } } */ -- cgit v1.2.3
