摘要
以在嵌入式系统中建立C编译器的技术特点为主要内容,用设计实例论述了C编译器实现中前端、后端的主要工作内容。说明了在前、后端之间起桥梁作用的中间描述语言有向无环图(DAG)的设计原理及形成方法,同时还就如何将DAG与目标机系统之间形成映射关系进行描述,提出了在映射中规约规则制定的方法和原则,给出了一些有指导意义的经验性结论。
This paper, based on the technology of building C compiler in embedded system, discusses the mainly work in realization of C compiler with design examples. The paper presents the design principle and the form method of the middle description language DAG, which has the bridge function between front end and back end. Also this paper describes the relation from DAG to target machine system, puts forward rules in maps about the method and principle of the rule establishment, and gives some experience conclusions that have guided meaning.
