【摘要】 提出一种基于头文件复用的大规模可变C代码增量式分析方法。以Linux内核代码为例,首先统计和分析了大规模C代码中的头文件包含情况。然后根据头文件包含顺序,构建C代码分析的头文件加载树。最后,按照头文件加载树增量地分析C代码。实验结果表明,与原有的代码分析方法相比,本方法可以极大地提升大规模可变C代码分析的效率。更多还原

【Abstract】 An incremental code parsing technique for large-scale variable C source code is proposed. Taking the Linux kernel source code as an example, firstly, we summarize and analyze the included header files in large-scale C source code. Then, header file loading trees are built according to the inclusion order of header files. Finally, the C source code is parsed incrementally based on the header file loading trees. The experimental results show that compared with the traditioanl code parsing methods, our method can greatly improve the efficiency of large-scale variable C source code parsing.更多还原
