Use opt -S instead of piping bitcode output through llvm-dis. llvm-svn: 81257 2009-09-09 06:34:10 +08:00			`; RUN: opt %s -instcombine -S \| 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
