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/tree-ssa/ldist-13.c | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/ldist-13.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/ldist-13.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/ldist-13.c b/gcc/testsuite/gcc.dg/tree-ssa/ldist-13.c new file mode 100644 index 000000000..984156954 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/ldist-13.c @@ -0,0 +1,22 @@ +/* { dg-do compile } */ +/* { dg-options "-O2 -ftree-loop-distribution -fdump-tree-ldist-details" } */ + +float * __restrict__ x; +float * __restrict__ y; + +float foo (int n) +{ + int i; + float tmp = 0.0; + for (i = 0; i < n; ++i) + { + x[i] = 0.0; + tmp += y[i]; + } + return tmp; +} + +/* We should apply loop distribution. */ + +/* { dg-final { scan-tree-dump "Loop 1 distributed: split to 2 loops" "ldist" } } */ +/* { dg-final { cleanup-tree-dump "ldist" } } */ -- cgit v1.2.3
