simplify some run lines, convert a test to filecheck. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83750 91177308-0d34-0410-b5e6-96231b3b80d8 2009-10-11 03:54:21 +00:00			`; RUN: opt < %s -jump-threading -S \| grep {ret i32 0}`
Fix PR3138: if we merge the entry block into another block, make sure to move the other block back up into the entry position! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60179 91177308-0d34-0410-b5e6-96231b3b80d8 2008-11-27 19:25:19 +00:00			`; PR3138`
