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/loop-6.c | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/loop-6.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/loop-6.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/loop-6.c b/gcc/testsuite/gcc.dg/tree-ssa/loop-6.c new file mode 100644 index 000000000..992f671e4 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/loop-6.c @@ -0,0 +1,28 @@ +/* { dg-do compile } */ +/* { dg-options "-O1 -funswitch-loops -fdump-tree-unswitch-details -fdump-tree-optimized" } */ + +int ch; +int a[100]; + +void xxx(void) +{ + int i; + + for (i = 0; i < 100; i++) + { + if (ch) + a[i] = ch; + else + a[i] = i; + } +} + +/* Loop should be unswitched. */ + +/* { dg-final { scan-tree-dump-times "Unswitching loop" 1 "unswitch" } } */ +/* { dg-final { cleanup-tree-dump "unswitch" } } */ + +/* In effect there should be exactly three conditional jumps in the final program. */ + +/* { dg-final { scan-tree-dump-times "else" 3 "optimized" } } */ +/* { dg-final { cleanup-tree-dump "optimized" } } */ -- cgit v1.2.3
