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/pr32964.c | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/pr32964.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/pr32964.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/pr32964.c b/gcc/testsuite/gcc.dg/tree-ssa/pr32964.c new file mode 100644 index 000000000..18e73f939 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/pr32964.c @@ -0,0 +1,26 @@ +/* { dg-do compile } */ +/* { dg-options "-O1 -fdump-tree-optimized" } */ + +union A +{ + float a; +}; + +float t(float a) +{ + union A a1, a2, a3; + int i; + + a1.a = a; + for(i = 0; i<100; i++) + { + a2 = a1; + a2.a += a; + a1 = a2; + } + a3 = a1; + return a3.a; +} + +/* { dg-final { scan-tree-dump-times "union" 0 "optimized"} } */ +/* { dg-final { cleanup-tree-dump "optimized" } } */ -- cgit v1.2.3
