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_1.c | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/ivopt_1.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/ivopt_1.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/ivopt_1.c b/gcc/testsuite/gcc.dg/tree-ssa/ivopt_1.c new file mode 100644 index 000000000..60baa4bd3 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/ivopt_1.c @@ -0,0 +1,18 @@ +/* { dg-do compile { target {{ i?86-*-* x86_64-*-* } && lp64 } } } */ +/* { dg-options "-O2 -m64 -fdump-tree-ivopts" } */ +#define TYPE char* + +/* Testing that only one induction variable is selected after IVOPT on + the given target instead of 3. */ +void foo (int i_width, TYPE dst, TYPE src1, TYPE src2) +{ + int x; + for( x = 0; x < i_width; x++ ) + { + dst[x] = ( src1[x] + src2[x] + 1 ) >> 1; + } +} + + +/* { dg-final { scan-tree-dump-times "PHI
