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/alias-6.c | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/alias-6.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/alias-6.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/alias-6.c b/gcc/testsuite/gcc.dg/tree-ssa/alias-6.c new file mode 100644 index 000000000..bcc011898 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/alias-6.c @@ -0,0 +1,21 @@ +/* { dg-do compile } */ +/* { dg-options "-O2 -fdump-tree-optimized" } */ + +struct param { int *a; }; +void foo(struct param *p); +int bar(void) +{ + int a[2]; + struct param p; + a[0] = 1; + a[1] = 1; + p.a = &a[0]; + foo(&p); + return a[0] + *p.a; +} + +/* We need to have both: a load from "a[0]" and a load from "*p.a", + the latter can be an ssa temporary. */ +/* { dg-final { scan-tree-dump "= a.0.;" "optimized" } } */ +/* { dg-final { scan-tree-dump "= \\*\[pD\]" "optimized" } } */ +/* { dg-final { cleanup-tree-dump "optimized" } } */ -- cgit v1.2.3
