The invention discloses a C language code dependency relationship extraction method based on static analysis, which comprises the following steps of: performing static analysis on a C language source code to obtain information of each macro instruction and information of each variable, function and type; for each macro instruction, extracting a dependency relationship generated by the macro instruction based on the macro instruction information; for each variable, extracting a dependency relationship generated by the variable based on each piece of variable information; for each function, extracting a dependency relationship generated by the function based on each piece of function information; for each type, extracting a dependency relationship generated by the type based on the type information; extracting a dependency relationship of a file level based on the dependency relationship of the symbol level; carrying out persistence on the extracted dependency relationship. According to the method, a more comprehensive, more accurate and multi-level dependency relationship is extracted from a C language source code.
Description
technical field [0001] The invention relates to the fields of computer technology and software engineering, in particular to a static analysis-based method for extracting dependencies of C language codes. Background technique [0002] With the development of modern software technology, the scale of software projects tends to be large, the coupling relationship between files and modules tends to be complicated, and the threshold of traditional experience-based software architecture design methods is getting higher and higher. Therefore, it is more and more important to automatically perform static analysis on the code and extract the multi-level dependencies of software projects. At the same time, the dependencies of software projects are also the underlying supporting data necessary to implement functions such as architecture analysis and software refactoring. [0003] At the same time, the existing static analysis work usually focuses on specific requirements and focuses o...
