Eliminate more uses of llvm-as and llvm-dis. llvm-svn: 81290 2009-09-09 01:54:48 +02:00			`; RUN: llc < %s -march=x86`
Make EXTRACT_VECTOR_ELT a bit more flexible in terms of the returned value. Adjust other code to deal with that correctly. Make DAGTypeLegalizer::PromoteIntRes_EXTRACT_VECTOR_ELT take advantage of this new flexibility to simplify the code and make it deal with unusual vectors (like <4 x i1>) correctly. Fixes PR3037. llvm-svn: 75176 2009-07-10 00:01:03 +02:00			`; PR3037`
