基于范型匹配的窥孔优化

Peephole Opimization Based on Pattern Matching

提出了基于范型匹配的窥孔优化技术，定义了窥孔优化的类。对每一个优化类，进行了范型匹配，使之能够产生一个匹配例程对应多个类的匹配摸式，改进了以往窥孔优化时的实现方法，提高了优化的质量与效率。

In this paper, the technique of peephole optindzation based on pattern matching is prented,and the clssification of peephole optimiztoin is defined,The optimizer matches each classification and makes a particular peephole routine which can be used for sev- eral different patterns.
