Improvement of instrumentation in program dynamic analysis system

Program dynamic analysis is an important method to understand program,while instrumentation is one of the key technologies used most frequently in program dynamic analysis.The instrument strategy of the dynamic analysis subsystem of the QESat/C++ tool is presented detailed,and the shortage of which is proposed also.Based on which the new instrumentor is raised,and the efficiency of the instrumentation library is improved.Through the experiment,the new dynamic analysis subsystem based on the improvement in-strumentation has the excellence of rapid instrumentation,smaller dynamic file size and higher efficiency of dynamic information com-bination.In the end,how to support others type of dynamic analysis is proposed and the paper is concluded.
