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/pr35286.c | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/pr35286.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/pr35286.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/pr35286.c b/gcc/testsuite/gcc.dg/tree-ssa/pr35286.c new file mode 100644 index 000000000..8601cabec --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/pr35286.c @@ -0,0 +1,23 @@ +/* { dg-do compile } */ +/* { dg-options "-O2 -fdump-tree-pre-stats" } */ +int g2; +struct A { + int a; int b; +}g1; +int foo(int a, int b) +{ + if (a > 0) + { + g1.a = a+ b; + } + else + g1.a = b; + + g2 = a+b; + + return g1.a; +} +/* We will eliminate the g1.a from the return statement as fully redundant, + and remove one calculation of a + b. */ +/* { dg-final { scan-tree-dump-times "Eliminated: 2" 1 "pre"} } */ +/* { dg-final { cleanup-tree-dump "pre" } } */ -- cgit v1.2.3
