* Several fixes to handling of int CC register:Vikram S. Adve2003-07-101-8/+10
| | | | | | | | | | | | | | | | | | | | | (1) An int CC live range must be spilled if there are any interferences, even if no other "neighbour" in the interf. graph has been allocated that reg. yet. This is actually true of any class with only one reg! (2) SparcIntCCRegClass::colorIGNode sets the color even if the LR must be spilled so that the machine-independent spill code doesn't have to make the machine-dependent decision of which CC name to use based on operand type: %xcc or %icc. (These are two halves of the same register.) (3) LR->isMarkedForSpill() is no longer the same as LR->hasColor(). These should never have been the same, and this is necessary now for #2. (4) All RDCCR and WRCCR instructions are directly generated with the phony number for %ccr so that EmitAssembly/EmitBinary doesn't have to deal with this. llvm-svn: 7152

* Extensive changes to the way code generation occurs for functionVikram S. Adve2003-05-312-157/+261
| | | | | | | | | | | | | | call arguments and return values: Now all copy operations before and after a call are generated during selection instead of during register allocation. The values are copied to virtual registers (or to the stack), but in the former case these operands are marked with the correct physical registers according to the calling convention. Although this complicates scheduling and does not work well with live range analysis, it simplifies the machine-dependent part of register allocation. llvm-svn: 6465
* (1) Added special register class containing (for now) %fsr.Vikram S. Adve2003-05-272-16/+15
| | | | | | | | | | | | | 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". llvm-svn: 6341
