Software fault debugging based on data flow analysis
Xi Guo, Pan Wang, Pengfei Wu · 2017
Data Flow Analysis is a difficult issue in the domain of fault localization, and many software faults are related to the information of data flow.The dependency between the variants and the define-use chain are discussed in this paper, and trace the impact to the variants in the process of operation.In this paper, a data flow model is proposed which can demonstrate the change of the variant value and the dependency between the variants and it can be used to debug the faults in the program.Experimental results demonstrate that this method has better results than the traditional methods.
