摘要:
A processor includes a front end, an execution pipeline, and a binary translator. The front end includes logic to receive an instruction and to dispatch the instruction to a binary translator. The binary translator includes logic to determine whether the instruction includes a control-flow instruction, identify a source address of the instruction, identify a target address of the instruction, determine whether the target address is a known destination based upon the source address, and determine whether to route the instruction to the execution pipeline based upon the determination whether the target address is a known destination based upon the source address. The target address includes an address to which execution would indirectly branch upon execution of the instruction.
