Zusammenfassung:A simulator includes a binary translator to translate target code into host instructions to be executed on a host processor. To identify target instructions which may be modified by self-modifying code, the simulator determines whether a target instruction to be translated resides in a writeable page, and if so, inserts a run-time check into a translation cache along with translated instructions corresponding to such target instructions.
