Problems solved by technology

During the teaching process, we found that conventional program analysis software cannot visually display the process and results of program analysis to students, and the analysis process is also uncontrollable
[0003] For example, cppcheck, a static inspection tool for code defects, can perform strict logical defect detection on c programs, but the software can only provide detection results, and the intermediate analysis results are invisible, and the analysis process is uncontrollable

Embodiment Construction

[0085] In order to make the purpose, technical solution, and advantages of the present invention clearer, the specific implementation examples of a service function authorization method and system involved in the present invention will be further described in detail below with reference to the accompanying drawings.

[0086] The basic principle of the program process visualization method described in the present invention is:

[0087] see figure 1 , the program process visualization method adopted in the present invention is composed of four modules, namely a program conversion module, a standardization module, a meta-level operation module, and an analysis result visualization module;

[0088] Program conversion module: convert the input source program into an intermediate representation;

[0089] Standardization module: delete information unrelated to data flow and control flow in the intermediate representation;

[0090] Meta-level operation module: perform o...

Abstract

The invention discloses a visualization method and system for program analysis processes. The method includes a program switch module, a standardized processing module, a meta-level operation module and a graphical display module, wherein the program switch module generates intermediate representation of a computer program; the standardized processing module normalizes and simplifies the intermediate representation of the program; the meta-level operation module provides the intermediate representation with a primary program modification mode; the graphical display module extracts information of data flows and control flows of the program, and displays an abstract syntax tree, a control flow diagram and a program dependence graph in a graphical mode. The visualization method and system for program analysis processes have the advantages of visually showing the whole processes of a program analysis, using a graph to demonstrate the result of the program analysis, and helping students better understand analysis processes and analysis methods of programs.

Description

Technical field [0001] The present invention relates to the field of program analysis, and in particular to a method and system for visualizing a program analysis process. Background technique [0002] Currently, program analysis tools or software focus on program analysis methods. The specific analysis process is abstract and unintuitive, making it unsuitable for teaching. During the teaching process, we found that conventional program analysis software cannot visually display the process and results of program analysis to students, and the analysis process is also uncontrollable. [0003] For example, the code defect static inspection tool cppcheck can perform strict logical defect detection on C programs, but the software can only provide detection results. The intermediate analysis results are not visible and the analysis process is uncontrollable. Contents of the invention [0004] The problem to be solved by the present invention is to provide a method and system fo...
