unsigned PIC16InstrInfo::isLoadFromStackSlot	(	const MachineInstr *	MI,
		int &	FrameIndex
	)			const [virtual]

isLoadFromStackSlot - If the specified machine instruction is a direct load from a stack slot, return the virtual or physical register number of the destination along with the FrameIndex of the loaded stack slot. If not, return 0. This predicate must return 0 if the instruction has any side effects other than loading from the stack slot.

isLoadFromStackSlot - If the specified machine instruction is a direct load from a stack slot, return the virtual or physical register number of the dest reg along with the FrameIndex of the stack slot. If not, return 0. This predicate must return 0 if the instruction has any side effects other than storing to the stack slot.

	)			const [virtual]

isStoreToStackSlot - If the specified machine instruction is a direct store to a stack slot, return the virtual or physical register number of the source reg along with the FrameIndex of the loaded stack slot. If not, return 0. This predicate must return 0 if the instruction has any side effects other than storing to the stack slot.

isStoreToStackSlot - If the specified machine instruction is a direct store to a stack slot, return the virtual or physical register number of the source reg along with the FrameIndex of the loaded stack slot.

	)			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.
