Abstract
A processor core stores information that maps a physical register to an architectural register in response to an instruction modifying the architectural register. The processor recovers a checkpointed state of a set of architectural registers prior to modification of the architectural register by the instruction by modifying a reference mapping of physical registers to the set of architectural registers using the stored information.
