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/pr25382.c | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/pr25382.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/pr25382.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/pr25382.c b/gcc/testsuite/gcc.dg/tree-ssa/pr25382.c new file mode 100644 index 000000000..daff68ee9 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/pr25382.c @@ -0,0 +1,19 @@ +/* PR tree-optimization/25382 + VRP used to ignore BIT_AND_EXPRs for the purpose of distilling ranges. + Check that VRP now gets ranges from BIT_AND_EXPRs. */ + +/* { dg-do compile } */ +/* { dg-options "-O2 -fno-tree-ccp -fdump-tree-vrp1" } */ + +int +foo (int a) +{ + int b = a & 0xff; + if (b > 300) + return 2; + else + return 1; +} + +/* { dg-final { scan-tree-dump-times "Folding predicate b_.* > 300 to 0" 1 "vrp1" } } */ +/* { dg-final { cleanup-tree-dump "vrp1" } } */ -- cgit v1.2.3
