* Generalize MVT::ValueType and associated functions to be able to representDan Gohman2007-06-255-153/+179
| | | | | | | | | | | | | | | | 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

* Replace M_REMATERIALIZIBLE and the newly-added isOtherReMaterializableLoadDan Gohman2007-06-191-12/+4
| | | | | | | | | | | with a general target hook to identify rematerializable instructions. Some instructions are only rematerializable with specific operands, such as loads from constant pools, while others are always rematerializable.
