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/ivopt_mult_3.c | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/ivopt_mult_3.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/ivopt_mult_3.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/ivopt_mult_3.c b/gcc/testsuite/gcc.dg/tree-ssa/ivopt_mult_3.c new file mode 100644 index 000000000..dc78a43f7 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/ivopt_mult_3.c @@ -0,0 +1,22 @@ +/* { dg-do compile { target {{ i?86-*-* x86_64-*-* } && lp64 } } } */ +/* { dg-options "-O2 -m64 -fdump-tree-ivopts-details" } */ + +/* iv p2 can be eliminated. */ +long foo(long* p, long* p2, int N1, int N2) +{ + unsigned long i = 0; + long* p_limit2 = p2 + N2; + long s = 0; + while (i < N1) + { + p2++; + i++; + if (p2 > p_limit2) + break; + s += p[i]; + } + return s; +} + +/* { dg-final { scan-tree-dump-times "Replacing" 1 "ivopts"} } */ +/* { dg-final { cleanup-tree-dump "ivopts" } } */ -- cgit v1.2.3
