    Abstract: A method and system in an information processing system are disclosed for efficiently maintaining copies of values stored within a plurality of registers. The information processing system includes first circuitry, second circuitry, and a plurality of buffers. The first circuitry processes an execution state of a first type of instruction which always specifies a destination of at least one of a first type of register or a second type of register, and which outputs first information in response thereto. The first circuitry also processes an execution stage of a second type of instruction which always specifies a destination of only a third type of register, and outputs second information in response thereto.
