Abstract
A method and apparatus for handling reusable and non-reusable code is herein described. Page table entries include code reuse and locality fields to hold hints for associated pages. If a code reuse and locality field holds a non-reusable value to indicate an associated page holds non-reusable code, then an instruction decoded from the associated page is not stored in the trace to obtain maximum efficiency and power savings from the trace cache and decode logic.
