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/pr24117.c | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/pr24117.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/pr24117.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/pr24117.c b/gcc/testsuite/gcc.dg/tree-ssa/pr24117.c new file mode 100644 index 000000000..ffa5dd04c --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/pr24117.c @@ -0,0 +1,24 @@ +/* { dg-do compile } */ +/* { dg-options "-O2 -fdump-tree-optimized" } */ + +typedef struct { + int x; + int z; +} Foo_t; + +char *xm; +void bar(void); + +void foo(void) +{ + Foo_t x; + x.x = 1; + x.z = 2; + xm = (char *)&x; + bar(); + /* We can't propagate x.z past bar, so this link_error should still be there. */ + if (x.z != 2) + link_error (); +} +/* { dg-final { scan-tree-dump-times "link_error" 1 "optimized"} } */ +/* { dg-final { cleanup-tree-dump "optimized" } } */ -- cgit v1.2.3
