| 摘 要： | 投机机制通过改善内存操作的效能而提高程序执行性能,但是它需要大量复杂的代码处理投机失败及恢复,增加了程序的理解和代码重建工作的复杂性。文章提出了投机代码消除技术,描述了如何应用该技术消除优化后的IA-64二进制代码中的投机指令,并证明了程序的语义不变,最终使得投机消除后的代码更容易理解,提高了对IA-64代码进行再工程的效率和代码质量。

| Abstract: | While performance can be improved still further by using a feature called speculation to ameliorate the effects of long latency memory operations,it requires a significant amount of complex support code to deal with and recover from speculation failures.This greatly complicates the tasks of understanding and re-engineering speculative code. This paper describes a technique for removing speculative instructions from optimized IA-64 binary programs in a way that is guaranteed to preserve program semantics,thereby making the resulting programs easier to understand and improving the quality and efficiency of IA-64 re-engineering. |
