2003-08-12For instructions in a delay slot of another instruction,Vikram S. Adve
we no longer need to find the live-before set of the delayed branch since that set is now included the live-before/after set of the instructions in each delay slot. Just assert that instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7796 91177308-0d34-0410-b5e6-96231b3b80d8

2003-07-25(1) Change the way unused regs. are marked and found to consider regTypeVikram S. Adve
info (since multiple reg types may share the same reg class). (2) Remove machine-specific regalloc. methods that are no longer needed. In particular, arguments and return value from a call do not need machine-specific code for allocation. (3) Rename TargetRegInfo::getRegType variants to avoid unintentional overloading when an include file is omitted. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7329 91177308-0d34-0410-b5e6-96231b3b80d8

2003-07-10Several fixes to handling of int CC register:Vikram S. Adve
(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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7152 91177308-0d34-0410-b5e6-96231b3b80d8

2003-05-31Extensive changes to the way code generation occurs for functionVikram S. Adve
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6465 91177308-0d34-0410-b5e6-96231b3b80d8
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
