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. llvm-svn: 81537 2009-09-11 20:01:28 +02:00			`; RUN: opt < %s -instcombine -S \| not grep div`
Add a couple of missed optimizations on integer vectors. Multiply and divide by 1, as well as multiply by -1. llvm-svn: 60182 2008-11-27 21:21:08 +01:00
