Design and Implementation of Peephole Optimization Based on Extensible Template

Optimization functions are crucial to compiler design. Generally, compiler optimization divides into machine-independent optimization based on the intermediate language and machine-dependent optimization based on the object code. In order to make use of the characteristics of the target machine, this paper presents an optimization scheme about peephole optimization based on extensible template, and introduces the implementation of this scheme for a C compiler of 16-bit embedded CPU system.
