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 -gvn -S \| not grep {%z2 =}`
Add a GVN pass, using the value numbering code I developed for GVNPRE and the load elimination code from RedundantLoadElimination. llvm-svn: 40469 2007-07-24 19:55:58 +02:00
