摘　　要：嵌入式系统的飞速发展使得必须快速地为之开发相应的编译器。LCC是一款可重定向的开源小型C编译器,基于LCC为嵌入式系统实现交叉编译器是种有效的途径。首先分析了LCC编译器的体系结构,然后说明了基于LCC的交叉编译器移植技术及其实现,并详细讨论了实现中的关键技术:交叉C编译器ABI的制定和DAG归约规则的制定。并根据实践经验总结出了3条对规约规则的制定具有指导作用的原则。With rapid development of embedded system now, the need for cross-compliers should be satisfied efficiently. LCC is a re- targetable open-source small C compile. It is a right method to implement cross compiler based on LCC. First the architecture of LCC is analysed, then implementation of cross compiler transplantation based on LCC is presented. The key technology of implement is di- scussed in detail, including providing C cross compiler ABI and giving DAG rules, and based on practical experience three guidelines is put forward for giving DAG rules.
