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/pr20742.c | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/pr20742.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/pr20742.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/pr20742.c b/gcc/testsuite/gcc.dg/tree-ssa/pr20742.c new file mode 100644 index 000000000..21d6eb63c --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/pr20742.c @@ -0,0 +1,18 @@ +/* { dg-do compile } */ +/* { dg-options "-O2" } */ + +#define TEN(x) x x x x x x x x x x +#define THOUSAND(x) TEN (TEN (TEN (x))) + +int +foo (int x, int y) +{ + register int a = y + 57; + register int b = y + 31; + + while (x-- > 0) + { + THOUSAND (a += b; b -= a;) + } + return a + b; +} -- cgit v1.2.3
