交叉汇编器设计

The Design of a Cross Assembler

本文讨论了交叉汇编器设计中的两个关键问题:先引用、后定义内部符号的处理和利用外部符号进行模间通信。提出了一种统一的处理办法——随机文件代真法。实践证明十分简洁有效。

In this paper, the author disscussed two key problems in the design of a cross assembler: the processing of 'define after use' internal symbols and the communication amdhg modules by external symbols. The author also presented and unified processing method——the random file substitute algorithm. It is proven in practice that the method is simple and efficient.
