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/pr21407.C | 8 ++++++++ 1 file changed, 8 insertions(+) create mode 100644 gcc/testsuite/g++.dg/tree-ssa/pr21407.C (limited to 'gcc/testsuite/g++.dg/tree-ssa/pr21407.C') diff --git a/gcc/testsuite/g++.dg/tree-ssa/pr21407.C b/gcc/testsuite/g++.dg/tree-ssa/pr21407.C new file mode 100644 index 000000000..561dc707a --- /dev/null +++ b/gcc/testsuite/g++.dg/tree-ssa/pr21407.C @@ -0,0 +1,8 @@ +/* { dg-do run } */ +/* { dg-options "-O2" } */ +extern "C" void abort(void); +struct T1 {int a, b; virtual void f(){}}; +struct T : T1 { struct T1 w; int b; }; +void foo (struct T1 *p) { struct T *q = dynamic_cast(p); if (q->b != 2) abort (); } +/* We shouldn't kill the store to c.b, because foo uses it. */ +int main () { struct T c; c.b = 2; foo (&c); return 0; } -- cgit v1.2.3
