基于XML Schema技术的编译符号表生成方法

传统的编译中间代码通常不能在移动、嵌入式和分布式等环境之间转换，而符号表的构造与管理贯穿整个中间代码的生成过程。本文提出一种基于XML Schema及其相关技术生成编译中间代码的符号表的方法。首先给出整体方案，然后阐述了如何运用XML Schema等技术表示编译器的前端，以及后端的目标机体系结构。生成的编译器符号表能通过XML工具统一管理和验证，从而使生成的编译中间代码有较高的可移植性，能被不同环境中的编译器采用。

A Compiler Symbol Table Generation Approach Based on XML Schema

Traditional compiling intermediate code is normally hard to be transformed between heterogeneous environments,such as mobile,embedded and distributed sstems.The building and management of symbol table is related with all stages of intermediate code.So a compiling symbol table building method based on XML Schema and its related techniques is proposed.Firstly,the design architecture of compiling process is given,then it expatiated how to represent front end and object machine architecture of backend of compiler.As a result,the symbol table can be managed and validated by XML tools,so the compiling intermediate code is with high portability,which can be applied and translated into compilers of different environments.
