Abstract
A method of responding to an attempt to write a memory address including a target instruction which has been translated to a host instruction for execution by a host processor including the steps of marking a memory address including a target instruction which has been translated to a host instruction, detecting a memory address which has been marked when an attempt is made to write to the memory address, and responding to the detection of a memory address which has been marked by protecting a target instruction at the memory address until it has been assured that translations associated with the memory address will not be utilized before being updated.
