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/reassoc-15.c | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/reassoc-15.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/reassoc-15.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/reassoc-15.c b/gcc/testsuite/gcc.dg/tree-ssa/reassoc-15.c new file mode 100644 index 000000000..df6fd5213 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/reassoc-15.c @@ -0,0 +1,21 @@ +/* { dg-do compile } */ +/* { dg-options "-O2 -fdump-tree-reassoc1" } */ + +unsigned int test3 (unsigned int x, unsigned int y, unsigned int z, + unsigned int weight, + unsigned int w1, unsigned int w2, unsigned int w3) +{ + unsigned int wtmp1 = w1 * weight; + unsigned int wtmp2 = w2 * weight; + unsigned int wtmp3 = w3 * weight; + unsigned int tmp1 = x * wtmp1; + unsigned int tmp2 = y * wtmp2; + unsigned int tmp3 = z * wtmp3; + return tmp1 + tmp2 + tmp3; +} + +/* The multiplication with weight should be un-distributed. + ???
