The Influence of Alias and References Escape on Java Program Analysis

摘要

The alias and references escape are often used in Java programs. They bring much convenience to the developers, but, they also give adverse affects on the data flow and control flow of program during program analysis. Therefore, when analyzing Java programs, we must consider the alias and references escape. This paper proposes a static approach to detecting control flow information of programs with alias and references escape. Firstly, it computes the data flow information, including def-use information and alias information caused by references assign and references escape. Secondly, it analyzes the program and gets the control flow information based on the obtained data flow information. Finally, a case study shows that the proposed method can detect control flow information exactly.
