Add a test case for PR1271 (necessary, but not sufficient). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35343 91177308-0d34-0410-b5e6-96231b3b80d8 2007-03-25 21:30:41 +00:00			`; PR1271`
Change tests from "opt %s" to "opt < %s" so that opt doesn't see the input filename so that opt doesn't print the input filename in the output so that grep lines in the tests don't unintentionally match strings in the input filename. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81537 91177308-0d34-0410-b5e6-96231b3b80d8 2009-09-11 18:01:28 +00:00			`; RUN: opt < %s -instcombine -S \| grep and`
