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/pr38895.c | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/pr38895.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/pr38895.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/pr38895.c b/gcc/testsuite/gcc.dg/tree-ssa/pr38895.c new file mode 100644 index 000000000..0a96e5334 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/pr38895.c @@ -0,0 +1,24 @@ +/* { dg-do compile } */ +/* { dg-options "-O -fstrict-aliasing -fdump-tree-optimized" } */ + +struct A { + int i; + int j; +}; +struct B { + struct A a1; + struct A a2; +}; +struct C { + struct A a1; + struct B b; +}; +int foo(struct C *c, struct B *b) +{ + c->a1.i = 1; + b->a1.i = 0; + return c->a1.i; +} + +/* { dg-final { scan-tree-dump "return 1;" "optimized" } } */ +/* { dg-final { cleanup-tree-dump "optimized" } } */ -- cgit v1.2.3
