Abstract:
A processor includes a core with logic to execute a translated instruction. The translated instruction is translated from an instruction stored in a memory location. The processor further includes a translation lookaside buffer including logic to store translation indicators from a physical map. Each translation indicator indicates whether a corresponding memory location includes translated code to be protected. The processor further includes a translation indicator agent including logic to determine whether the buffer indicates whether the memory location has been modified subsequent to translation of the instruction.
