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/reassoc-13.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/reassoc-13.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/reassoc-13.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/reassoc-13.c b/gcc/testsuite/gcc.dg/tree-ssa/reassoc-13.c new file mode 100644 index 000000000..f05401cba --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/reassoc-13.c @@ -0,0 +1,15 @@ +/* { dg-do compile } */ +/* { dg-options "-O -ffast-math -fdump-tree-reassoc1 -fdump-tree-optimized" } */ + +double foo(double a) +{ + double tmp = 5.0; + double tmp2 = a + tmp; + tmp2 = tmp2 - a; + return a + tmp2 - 5.0; +} + +/* { dg-final { scan-tree-dump-not "\\\+ 0.0" "reassoc1" } } */ +/* { dg-final { scan-tree-dump "return a_..D.;" "optimized" } } */ +/* { dg-final { cleanup-tree-dump "reassoc1" } } */ +/* { dg-final { cleanup-tree-dump "optimized" } } */ -- cgit v1.2.3
