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 2009-09-12 02:01:28 +08:00			`; RUN: opt < %s -simplifycfg \| llvm-dis`
fix a bug I introduced in simplifycfg handling single entry phi nodes. FoldSingleEntryPHINodes deletes the PHI, so there is no need to delete it afterward. llvm-svn: 60653 2008-12-07 15:22:45 +08:00			`define i32 @test() {`
