Dan Gohman	7f32156bb9	Generalize MVT::ValueType and associated functions to be able to represent ... extended vector types. Remove the special SDNode opcodes used for pre-legalize vector operations, and the special MVT::Vector type used with them. Adjust lowering and legalize to work with the normal SDNode kinds instead, and to use the normal MVT functions to work with vector types instead of using the two special operands that the pre-legalize nodes held. This allows pre-legalize and post-legalize DAGs, and the code that operates on them, to be more consistent. Pre-legalize vector operators can be handled more consistently with scalar operators. And, -view-dag-combine1-dags and -view-legalize-dags now look prettier for vector code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37719 91177308-0d34-0410-b5e6-96231b3b80d8	2007-06-25 16:23:39 +00:00
