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 \| llvm-dis`
Folding or(fcmp,fcmp) only works if the operands of the fcmps are the same fp type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47750 91177308-0d34-0410-b5e6-96231b3b80d8 2008-02-29 06:09:11 +00:00			`; rdar://5771353`
