ABSTRACT:
The invention includes a method and apparatus for maintaining content of predefined registers of a processor which uses the registers for executing instructions, including an interruptible instruction. According to the invention, instructions are dispatched, including instructions ("targeting instructions") which target registers for holding register content, and an interruptible instruction. The content of a register is altered in response to executing a targeting instruction. An entry of register content is stored only for selected ones of the dispatched targeting instructions.
