Abstract

The invention provides a program slicing based parallelization method and device of code defect static detection. The program slicing based parallelization method comprises splitting a detection object into a plurality of sub-objects which are mutually independent by a program slicing technology and executing the code defect static detection of every sub-object in a parallel mode. According to the program slicing based parallelization method and device of the code defect static detection, the object to be detected is divided into the plurality of sub-objects which are mutually independent by the program slicing technology, the detection processes of the sub-objects are not interfered with each other, the code defect static detection of every sub-object can be executed in a parallel mode, and accordingly the efficiency and the accuracy of the static detection are improved.

Description

technical field [0001] The invention relates to a code defect static detection technology, in particular to a parallel method and device for code defect static detection based on program slicing. Background technique [0002] At present, the problem of low efficiency is common in static code defect detection systems, that is, the massive execution paths to be analyzed need to consume a lot of time and resources, especially in the case of path explosion, static analysis is often computationally infeasible. As the size and complexity of software increase, this problem will become more and more serious. The current mainstream defect detection system only relies on introducing some heuristic rules and setting the analysis upper bound to limit the analysis work to an acceptable range. However, this limitation will inevitably cause some paths not to be analyzed, which will affect the detection accuracy and cause some code defects to be missed. [0003] At present, the computing ...
