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/pr19633.c | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/pr19633.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/pr19633.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/pr19633.c b/gcc/testsuite/gcc.dg/tree-ssa/pr19633.c new file mode 100644 index 000000000..01c7eec31 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/pr19633.c @@ -0,0 +1,26 @@ +/* { dg-do compile } */ +/* { dg-options "-O1 -fdump-tree-ssa-vops" } */ +struct S +{ + int w, x, y, z; +}; +struct T +{ + int r; + struct S s; +}; +void bar (struct S, int); +void +foo (int a, struct T b) +{ + struct S x; + struct S *c = &x; + if (a) + c = &b.s; + bar (*c, a); +} + +/* Make sure that .GLOBAL_VAR is not created when there are no + clobbering calls. */ +/* { dg-final { scan-tree-dump-times "GLOBAL_VAR" 0 "ssa"} } */ +/* { dg-final { cleanup-tree-dump "ssa" } } */ -- cgit v1.2.3
