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/pr31146.C | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) create mode 100644 gcc/testsuite/g++.dg/tree-ssa/pr31146.C (limited to 'gcc/testsuite/g++.dg/tree-ssa/pr31146.C') diff --git a/gcc/testsuite/g++.dg/tree-ssa/pr31146.C b/gcc/testsuite/g++.dg/tree-ssa/pr31146.C new file mode 100644 index 000000000..478a488e3 --- /dev/null +++ b/gcc/testsuite/g++.dg/tree-ssa/pr31146.C @@ -0,0 +1,16 @@ +/* { dg-do compile } */ +/* { dg-options "-O -fdump-tree-forwprop" } */ + +/* We should be able to optimize this to i[j] = 1 during + early optimizations. */ + +int i[5]; +void foo (int j) +{ + void *p = &i[j]; + int *q = (int *)p; + *q = 1; +} + +/* { dg-final { scan-tree-dump "MEM\\\[.*&i\\\]\\\[j.*\\\] =.* 1;" "forwprop1" } } */ +/* { dg-final { cleanup-tree-dump "forwprop?" } } */ -- cgit v1.2.3
