Abstract
A method for maintaining consistency between translated host instructions and target instructions from which the host instructions have been translated including the steps of maintaining a copy of a target instruction for which a translated host instruction have been made, comparing the copy of the target instruction with a target instruction at a memory address at which the target instruction from which the copy was made was stored when translated, disabling the translated host instruction if the copy of the target instruction is not the same as the target instruction at the memory address, and executing the translated host instruction if the copy of the target instruction is the same as the target instruction at the memory address.
