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/ssa-pre-2.c | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/ssa-pre-2.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/ssa-pre-2.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/ssa-pre-2.c b/gcc/testsuite/gcc.dg/tree-ssa/ssa-pre-2.c new file mode 100644 index 000000000..311f12781 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/ssa-pre-2.c @@ -0,0 +1,24 @@ +/* { dg-do compile } */ +/* { dg-options "-O2 -fdump-tree-pre-stats" } */ +int motion_test1(int data, int data_0, int data_3, int v) +{ + int i; + int t, u; + + if (data) + i = data_0 + data_3; + else { + v = 2; + i = 5; + } + t = data_0 + data_3; + u = i; + return v * t * u; +} +/* We should eliminate one computation of data_0 + data_3 along the + main path.
