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 -simplify-libcalls -S \| grep i32`
Fix PR2341 - when the length is 4 use an i32 not an i16! Cleaned up trailing whitespace while there. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51240 91177308-0d34-0410-b5e6-96231b3b80d8 2008-05-19 09:27:24 +00:00			`; PR2341`
