2003-05-27(1) Added special register class containing (for now) %fsr.Vikram S. Adve
Fixed spilling of %fcc[0-3] which are part of %fsr. (2) Moved some machine-independent reg-class code to class TargetRegInfo from SparcReg{Class,}Info. (3) Renamed MachienOperand::opIsDef to MachineOperand::opIsDefOnly() and related functions and flags. Fixed several bugs where only "isDef" was being checked, not "isDefAndUse". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6341 91177308-0d34-0410-b5e6-96231b3b80d8
2003-05-12Use a kill, not a dead definition, update commentChris Lattner

2003-05-12* Keep LiveVariable information more up-to-date and consistentChris Lattner
* *** Finally mark values that are inputs to PHIs as killed when appropriate. This should make the generated code quite a bit better. For example, the local-ra will not have to spill PHI inputs at the end of predecessor BB's anymore. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6117 91177308-0d34-0410-b5e6-96231b3b80d8
