const SparcRegisterInfo& llvm::SparcInstrInfo::getRegisterInfo ( ) const [inline]

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).

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.

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.
