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/pr19637.C | 33 +++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) create mode 100644 gcc/testsuite/g++.dg/tree-ssa/pr19637.C (limited to 'gcc/testsuite/g++.dg/tree-ssa/pr19637.C') diff --git a/gcc/testsuite/g++.dg/tree-ssa/pr19637.C b/gcc/testsuite/g++.dg/tree-ssa/pr19637.C new file mode 100644 index 000000000..2d1dcceba --- /dev/null +++ b/gcc/testsuite/g++.dg/tree-ssa/pr19637.C @@ -0,0 +1,33 @@ +/* { dg-do compile } */ +/* { dg-options "-O2 -fdump-tree-dom1" } */ + +#include + +struct Foo { + Foo() { i[0] = 1; } + int i[2]; +}; + +int foo_char(void) +{ + int i[2]; + new (reinterpret_cast(i)) Foo(); + return reinterpret_cast(i)->i[0]; +} + +int foo_void(void) +{ + int i[2]; + new (reinterpret_cast(i)) Foo(); + return reinterpret_cast(i)->i[0]; +} + +int foo_void_offset(void) +{ + int i[2]; + new (reinterpret_cast(&i[0])) Foo(); + return reinterpret_cast(&i[0])->i[0]; +} + +/* { dg-final { scan-tree-dump-times "return 1;" 3 "dom1" } } */ +/* { dg-final { cleanup-tree-dump "dom1" } } */ -- cgit v1.2.3
