2003-12-14Change interface of MachineOperand as follows:Alkis Evlogimenos
a) remove opIsUse(), opIsDefOnly(), opIsDefAndUse() b) add isUse(), isDef() c) rename opHiBits32() to isHiBits32(), opLoBits32() to isLoBits32(), opHiBits64() to isHiBits64(), opLoBits64() to isLoBits64(). This results to much more readable code, for example compare "op.opIsDef() || op.opIsDefAndUse()" to "op.isDef()" a pattern used very often in the code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10461 91177308-0d34-0410-b5e6-96231b3b80d8

2003-11-10Fix problems linking against the reoptimizer; _llvm_regAllocState must haveBrian Gaeke
externally-visible linkage, and SaveStateToModule must default to true for llc. I don't remember why I made it const; perhaps it should be deconstified. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9858 91177308-0d34-0410-b5e6-96231b3b80d8
2003-11-10Operand numbers are now ints. Save the register allocation of the valueBrian Gaeke
each instruction produces as "operand" -1, and the other operands as 0 .. n, as before. PhyRegAlloc::saveState() is refactored into PhyRegAlloc::saveStateForValue(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9842 91177308-0d34-0410-b5e6-96231b3b80d8
2003-11-04Update verifySavedState()'s comment, so that it reflects its currentBrian Gaeke
status. In doFinalization(), skip over external functions, just like Anand's mapping info does. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9703 91177308-0d34-0410-b5e6-96231b3b80d8

2003-10-30Include llvm/CodeGen/MachineCodeForInstruction.h. Use it to startBrian Gaeke
implementing verifySavedState(). In saveState(), use the new AllocInfo::AllocStateTy enum, and increment Insn each time through the loop. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9617 91177308-0d34-0410-b5e6-96231b3b80d8
2003-10-24Publicize the type of FnAllocState.Brian Gaeke
Prototype option to save state in a global instead of as a Constant in the Module. (Turned off, for now, with the on/off switch welded in the off position. You get the idea.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9500 91177308-0d34-0410-b5e6-96231b3b80d8
2003-10-23Move AllocInfo structure to a private AllocInfo.h header file.Brian Gaeke
Make FnAllocState contain vectors of AllocInfo, instead of LLVM Constants. Give doFinalization a method comment, and let it do the work of converting AllocInfos to LLVM Constants. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9451 91177308-0d34-0410-b5e6-96231b3b80d8

2003-10-22Don't worry about converting each function's reg. alloc. state into One BigBrian Gaeke
Constant early on, because we can do it in doFinalization. Tighten up a comment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9387 91177308-0d34-0410-b5e6-96231b3b80d8
2003-10-22Doxygenify method comments.Brian Gaeke
Try to improve method comments a little. Get rid of some excess whitespace; put braces on previous line when possible. Add stub for method to verify the work of saveState(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9385 91177308-0d34-0410-b5e6-96231b3b80d8

2003-09-24Use getRegClassID() instead of getRegClass()->getID(), since it's there.Brian Gaeke
Shorten the markSuggestedColorUsable method. Add a switch for saving reg. alloc. state (coming soon). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8697 91177308-0d34-0410-b5e6-96231b3b80d8

2003-09-21Rearrange #includes ... since there are fewer now I guess it's a win.Brian Gaeke
(I also zapped printMachineCode() and printLabel() at the previous checkin, but forgot to mention it.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8646 91177308-0d34-0410-b5e6-96231b3b80d8

excess whitespace a little. Also improved some comments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8642 91177308-0d34-0410-b5e6-96231b3b80d8
2003-09-21Convert PhyRegAlloc into a proper pass.Brian Gaeke
PhyRegAlloc.cpp: Don't include TargetMachine.h or TargetRegInfo.h, because these are provided by PhyRegAlloc.h. Merge class RegisterAllocator into class PhyRegAlloc. Simplify & move ctor, dtor to PhyRegAlloc.h. Make some of PhyRegAlloc's reference members into pointer members, so they can be more easily messed with. MarkAllocatedRegs() becomes a member method, with fewer args. PhyRegAlloc.h: Include Pass.h, TargetMachine.h and TargetRegInfo.h. Don't declare TargetRegInfo forward. Give AddedInstrns the obvious clear() method. Make some of PhyRegAlloc's reference members into pointer members, so they can be more easily messed with. Add prototype for markAllocatedRegs(). Remove unused inline void constructLiveRanges(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8641 91177308-0d34-0410-b5e6-96231b3b80d8

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

2003-07-291. Bug fix: Don't use branch operand reg. as temp. reg. whenVikram S. Adve
spilling values used by an instruction in the delay slot of the branch (which will eventually be moved before the branch). 2. Bug fix: Delete the delay slot instr, not the branch instr, when moving delay slot instr. out!!!! 3. Move code to insert caller-saves moved here from SparcRegInfo: it is now machine-independent. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7389 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7350 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
2003-07-02Minor beautification: fold a couple of lines of code.Vikram S. Adve
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7054 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
