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
2003-11-11Put all LLVM code into the llvm namespace, as per bug 109.Brian Gaeke

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
2003-10-30Make AllocState an enum.Brian Gaeke
Move the stringifying method for that enum into class AllocInfo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9616 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 the implementations of ==, != on AllocInfos here, from UnpackTraceFunction.Brian Gaeke
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9452 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

2003-09-21Convert 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
