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_infer_2.c | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/ivopt_infer_2.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/ivopt_infer_2.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/ivopt_infer_2.c b/gcc/testsuite/gcc.dg/tree-ssa/ivopt_infer_2.c new file mode 100644 index 000000000..4b7e197dd --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/ivopt_infer_2.c @@ -0,0 +1,25 @@ +/* { dg-do compile { target {{ i?86-*-* x86_64-*-* } && lp64 } } } */ +/* { dg-options "-O2 -m64 -fdump-tree-ivopts-details" } */ + +#ifndef TYPE +#define TYPE char* +#endif + +extern int a[]; + +/* Can not infer loop iteration from array -- exit test can not be replaced. */ +void foo (int i_width, TYPE dst, TYPE src1, TYPE src2) +{ + TYPE dstn= dst + i_width; + TYPE dst0 = dst; + unsigned long long i = 0; + for( ; dst <= dstn; ) + { + dst0[i] = ( src1[i] + src2[i] + 1 +a[i]) >> 1; + dst++; + i += 16; + } +} + +/* { dg-final { scan-tree-dump-times "Replacing" 0 "ivopts"} } */ +/* { dg-final { cleanup-tree-dump "ivopts" } } */ -- cgit v1.2.3
