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/ldist-10.c | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/ldist-10.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/ldist-10.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/ldist-10.c b/gcc/testsuite/gcc.dg/tree-ssa/ldist-10.c new file mode 100644 index 000000000..0790c18a9 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/ldist-10.c @@ -0,0 +1,24 @@ +/* { dg-do compile } */ +/* { dg-options "-O2 -ftree-loop-distribution -fdump-tree-ldist-all" } */ + +int loop1 (int k) +{ + unsigned int i; + int a[1000], b[1000], c[1000]; + + for (i = 1; i < 1000; i ++) + { + a[i] = c[i]; /* S1 */ + b[i] = a[i-1]+1; /* S2 */ + } + /* Dependences: + S1->S2 (flow, level 1) + + One partition as A is used in both S1 and S2. + */ + + return a[1000-2] + b[1000-1] + c[1000-2]; +} + +/* { dg-final { scan-tree-dump-times "distributed: split to 2 loops" 0 "ldist" } } */ +/* { dg-final { cleanup-tree-dump "ldist" } } */ -- cgit v1.2.3
