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-outer-4b.c | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/vect/vect-outer-4b.c (limited to 'gcc/testsuite/gcc.dg/vect/vect-outer-4b.c') diff --git a/gcc/testsuite/gcc.dg/vect/vect-outer-4b.c b/gcc/testsuite/gcc.dg/vect/vect-outer-4b.c new file mode 100644 index 000000000..407315a8d --- /dev/null +++ b/gcc/testsuite/gcc.dg/vect/vect-outer-4b.c @@ -0,0 +1,26 @@ +/* { dg-do compile } */ + +#define N 40 +#define M 128 +signed short in[N+M]; +signed short coeff[M]; +int out[N]; + +/* Outer-loop vectorization. */ + +void +foo (){ + int i,j; + int diff; + + for (i = 0; i < N; i++) { + diff = 0; + for (j = 0; j < M; j+=8) { + diff += in[j+i]*coeff[j]; + } + out[i]=diff; + } +} + +/* { dg-final { scan-tree-dump-times "OUTER LOOP VECTORIZED" 1 "vect" { target vect_widen_mult_hi_to_si } } } */ +/* { dg-final { cleanup-tree-dump "vect" } } */ -- cgit v1.2.3
