◆ getRegisterInfo()

const VERegisterInfo & llvm::VEInstrInfo::getRegisterInfo ( ) const

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.
