基于GCC的抽象语法树对C++源程序结构的分析

Analysis of the C++ Source Program Structure Based on GCC Abstract Syntax Tree

源程序静态信息的提取是实现对源程序静态分析的基础,提取的静态信息的完整性、信息的规范性是静态分析的关键点。文章基于GCC编译器产生的AST(AbstractSyntaxTree)中间文件,给出了一种从AST文件中提取源程序的静态信息的方法,以XML(ExtensibleMarkupLanguage)标准格式输出,最后树形化地显示出源程序的结构关系。

Extracting the static information from source code is the foundation of static source code analysis.Integrality and specification of static information are the key for static analysis.This paper presents a method to extract information from AST fdes the GCC has dumped and output the information in the XML format.At last,the structure of program is displayed in tree view.
