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_2.c | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/ivopt_2.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/ivopt_2.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/ivopt_2.c b/gcc/testsuite/gcc.dg/tree-ssa/ivopt_2.c new file mode 100644 index 000000000..ba87b502c --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/ivopt_2.c @@ -0,0 +1,17 @@ +/* { dg-do compile { target {{ i?86-*-* x86_64-*-* } && lp64 } } } */ +/* { dg-options "-O2 -m64 -fdump-tree-ivopts" } */ + +#define TYPE char* + +/* Testing on the given target, only one iv candidate instead of 3. */ +void foo (int i_width, TYPE dst, TYPE src1, TYPE src2) +{ + int x; + for( x = 0; x < i_width; x++ ) + { + *dst++ = ( *src1++ + *src2++ + 1 ) >> 1; + } +} + +/* { dg-final { scan-tree-dump-times "PHI
