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-dse-11.c | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/ssa-dse-11.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/ssa-dse-11.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/ssa-dse-11.c b/gcc/testsuite/gcc.dg/tree-ssa/ssa-dse-11.c new file mode 100644 index 000000000..6e13e1875 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/ssa-dse-11.c @@ -0,0 +1,21 @@ +/* { dg-do compile } */ +/* { dg-options "-O -fdump-tree-dse1-details" } */ + +extern void abort(void); +void foo(int *p) +{ + while (1) + { + *p = 1; + *p = 0; + } +} +void bar(int *p) +{ + *p = 1; + *p = 0; + abort (); +} + +/* { dg-final { scan-tree-dump-times "Deleted dead store" 2 "dse1" } } */ +/* { dg-final { cleanup-tree-dump "dse1" } } */ -- cgit v1.2.3
