Alkis Evlogimenos 8cdd0215bf Remove getAllocatedRegNum(). Use getReg() instead.

Alkis Evlogimenos 80da865f77 Change MachineBasicBlock's vector of MachineInstr pointers into an
ilist of MachineInstr objects. This allows constant time removal and
insertion of MachineInstr instances from anywhere in each
MachineBasicBlock. It also allows for constant time splicing of
MachineInstrs into or out of MachineBasicBlocks.

Chris Lattner 5dd5be3ec3 Do not use MachineOperand::isVirtualRegister either!

Alkis Evlogimenos aaba4639f8 Change interface of MachineOperand as follows:
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.

Vikram S. Adve 7366fa1aa6 (1) Added special register class containing (for now) %fsr.
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".

Chris Lattner 1103e8349d Use a kill, not a dead definition, update comment

Chris Lattner 51ae817fd6 * Keep LiveVariable information more up-to-date and consistent
* *** Finally mark values that are inputs to PHIs as killed when appropriate.
   This should make the generated code quite a bit better.  For example, the
   local-ra will not have to spill PHI inputs at the end of predecessor BB's
   anymore.
