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

2003-06-07Do not hastily change the Opcode from 'r' to 'i' type if we're not actuallyMisha Brukman
SETTING the operand to be an immediate or have verified that one of the operands is really a SignExtended or Unextended immediate value already, which warrants an 'i' opcode. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6662 91177308-0d34-0410-b5e6-96231b3b80d8

2003-06-04I have finally seen the light. The code to change the opcode must live higher inMisha Brukman
the loop, and in both cases. In the first case, it is a VReg that is a constant so it may be actually converted to a constant. In the second case, it is already a constant, but then if it doesn't change its type (e.g. to become a register and have the value loaded from memory if it is too large to live in its instruction field), we must change the opcode BEFORE the 'continue', otherwise we miss the opportunity. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6602 91177308-0d34-0410-b5e6-96231b3b80d8

2003-05-31Added MachineCodeForInstruction object as an argument toVikram S. Adve
TmpInstruction constructors because every TmpInstruction object has to be registered with a MachineCodeForInstruction to prevent leaks. This simplifies the user's code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6469 91177308-0d34-0410-b5e6-96231b3b80d8
2003-05-31Allow explicit physical registers for implicit operands.Vikram S. Adve
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6468 91177308-0d34-0410-b5e6-96231b3b80d8
2003-05-31Changes to allow explicit physical register arguments that have beenVikram S. Adve
preallocated. While reg-to-reg dependences were already handled, this change required new code for adding edges to/from call instructions. This was part of the extensive changes to the way code generation occurs for function call arguments and return values. See log for CodeGen/PhyRegAlloc.cpp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6467 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

2003-05-27Added a debugging code emitter that prints code to a file, debug to std::cerr,Misha Brukman
and passes the real code to a memory-outputting code emitter. This may be removed at a later point in development. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6379 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
