| Summary: | Program analysis is the prime method to program property analysis,which is widely used in the domain of parameter dependent relation,path coverage and test case generation,and a lot of progress has been made.Current program analysis is based on the method of symbolic execution,but symbolic execution is usually tackled with the problems of logic expression generation of path condition and low efficiency of constrain solver,which will affect the results of program analysis.Aiming at enhancing the path analysis efficiency,the path conditions of different paths were collected,the common symbolic expression was extracted and the efficiency of symbolic analysis was enhanced,then the logic expression set was generated,the dependent relation algorithm was used to enhance the efficiency of symbolic analysis.Experimental results demonstrate that the proposed method has the advantages of accurate time complexity and better analysis efficiency compare to traditional program analysis method. |
