Change these tests to feed the assembly files to opt directly, instead of using llvm-as, now that opt supports this. llvm-svn: 81226 2009-09-09 00:50:01 +08:00			`; RUN: opt %s -instcombine \| llvm-dis \| grep zeroinitializer`
Handle a special case xor undef, undef -> 0. Technically this should be transformed to undef. But this is such a common idiom (misuse) we are going to handle it. llvm-svn: 48791 2008-03-26 04:07:13 +08:00
