动态二进制翻译中的冗余LOAD删除优化技术

OPTIMIZATION TECHNIQUE OF LOAD REDUNDANCY ELIMINATION IN DYNAMIC BINARY TRANSLATION

动态二进制翻译系统是根据程序的动态执行信息来将源机器上的可执行代码翻译成目标机器上的可执行代码。在翻译成中间表示的过程中会产生一些冗余的LOAD指令,为提高代码的执行效率,提出对这些LOAD指令进行冗余删除优化。该优化技术可以使优化效果超过其自身的开销,达到优化的目的。

Dynamic binary translation system is the translation process for the executable code from source machine to target machine according to dynamic executive information. In the translation process at intermediate representation stage, many redundant LOAD instructions will be generated. In this paper it presents an optimization of redundancy elimination for improving execution efficiency of the codes. It is such a technique with optimized effect exceeding its cost and achieves the goal of optimization.
