public final class RegisterValue
extends AllocatableValue

Denotes a register that stores a value of a fixed kind. There is exactly one (canonical) instance of RegisterValue for each (Register, Kind) pair. Use Register.asValue(LIRKind) to retrieve the canonical RegisterValue instance for a given (register,kind) pair.
