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/ssa-dce-2.c | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/ssa-dce-2.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/ssa-dce-2.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/ssa-dce-2.c b/gcc/testsuite/gcc.dg/tree-ssa/ssa-dce-2.c new file mode 100644 index 000000000..5e5302486 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/ssa-dce-2.c @@ -0,0 +1,17 @@ +/* { dg-do compile } */ +/* { dg-options "-O2 -fdump-tree-dce2" } */ + +/* We should notice constantness of this function. */ +static int __attribute__((noinline)) t(int a) +{ + return a+1; +} +void q(void) +{ + int i = t(1); + if (!i) + i = t(1); +} +/* There should be no IF conditionals. */ +/* { dg-final { scan-tree-dump-times "if " 0 "dce2"} } */ +/* { dg-final { cleanup-tree-dump "dce2" } } */ -- cgit v1.2.3
