Abstract
Provided is a method and system for encoding an instruction to restore processor core register values. The method includes encoding in a first field of the instruction whether a first value, in a stack memory location having an address value equal to A plus a second value in a second register, is to be restored to a first register. A third value is encoded in a second field of the instruction for adjusting the second value in the second register.
