virtual const IA64RegisterInfo& llvm::IA64InstrInfo::getRegisterInfo

(

)

const [inline, 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).

		unsigned &	SrcReg,
		unsigned &	DstReg,
		unsigned &	SrcSubIdx,

	)			const [virtual]

Return true if the instruction is a register to register move and return the source and dest operands and their sub-register indices by reference.

		MachineBasicBlock *	TBB,
		MachineBasicBlock *	FBB,
		const SmallVectorImpl< MachineOperand > &	Cond
	)			const [virtual]

InsertBranch - Insert a branch into the end of the specified MachineBasicBlock. This operands to this method are the same as those returned by AnalyzeBranch. This is invoked in cases where AnalyzeBranch returns success and when an unconditional branch (TBB is non-null, FBB is null, Cond is empty) needs to be inserted. It returns the number of instructions inserted.

	)			const [virtual]

copyRegToReg - Emit instructions to copy between a pair of registers. It returns false if the target does not how to copy between the specified registers.

	)			const [virtual]

storeRegToStackSlot - Store the specified register of the given register class to the specified stack frame index. The store instruction is to be added to the given machine basic block before the specified machine instruction. If isKill is true, the register operand is the last use and must be marked kill.
