Abstract

A method of compiling code includes ordering instructions that protect and release critical sections in the code to improve parallel execution of the code according to an intrinsic order of the critical sections. According to one embodiment, the intrinsic order of the critical sections in the code is determined from data dependence and control dependence of instructions in the critical sections, and additional dependencies are generated to enforce the intrinsic order of the critical sections. Other embodiments are described and claimed.
