Change interface of MachineOperand as follows: · aaba4639

Alkis Evlogimenos authored Dec 14, 2003

    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.

(1) Added special register class containing (for now) %fsr. · 7366fa1a

Vikram S. Adve authored May 27, 2003

    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".
