getNoopForMachoTarget - Return the noop instruction to use for a noop.

const Thumb2RegisterInfo& llvm::Thumb2InstrInfo::getRegisterInfo

(

)

const [inline, override, virtual]

getRegisterInfo - TargetInstrInfo is a superset of MRegister info. As such, whenever a client has an instance of instruction info, it should always be able to get register info as well (through this method).

Implements llvm::ARMBaseInstrInfo.
