Chris Lattner 27a6c7380f Several changes: ... 1) Change the interface to TargetLowering::ExpandOperationResult to take and return entire NODES that need a result expanded, not just the value. This allows us to handle things like READCYCLECOUNTER, which returns two values. 2) Implement (extremely limited) support in LegalizeDAG::ExpandOp for MERGE_VALUES. 3) Reimplement custom lowering in LegalizeDAGTypes in terms of the new ExpandOperationResult. This makes the result simpler and fully general. 4) Implement (fully general) expand support for MERGE_VALUES in LegalizeDAGTypes. 5) Implement ExpandOperationResult support for ARM f64->i64 bitconvert and ARM i64 shifts, allowing them to work with LegalizeDAGTypes. 6) Implement ExpandOperationResult support for X86 READCYCLECOUNTER and FP_TO_SINT, allowing them to work with LegalizeDAGTypes. LegalizeDAGTypes now passes several more X86 codegen tests when enabled and when type legalization in LegalizeDAG is ifdef'd out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44300 91177308-0d34-0410-b5e6-96231b3b80d8		2007-11-24 07:07:01 +00:00
