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/g++.dg/tree-ssa/pr33593.C | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) create mode 100644 gcc/testsuite/g++.dg/tree-ssa/pr33593.C (limited to 'gcc/testsuite/g++.dg/tree-ssa/pr33593.C') diff --git a/gcc/testsuite/g++.dg/tree-ssa/pr33593.C b/gcc/testsuite/g++.dg/tree-ssa/pr33593.C new file mode 100644 index 000000000..f5497407f --- /dev/null +++ b/gcc/testsuite/g++.dg/tree-ssa/pr33593.C @@ -0,0 +1,19 @@ +/* { dg-do compile } */ +/* { dg-options "-O1 -fnon-call-exceptions -fdump-tree-optimized" } */ + +#include + +void foo (int) { printf ("Bar\n"); } + +int +main (void) +{ + int a = 1 / 0; // { dg-warning "division by zero" } + printf ("Foo\n"); + foo (a); +} + +// The expression 1 / 0 should not be propagated into the call to foo() if it +// may trap. +// { dg-final { scan-tree-dump-times "foo \\(1 \\/ 0\\)" 0 "optimized" } } +// { dg-final { cleanup-tree-dump "optimized" } } -- cgit v1.2.3
