| 摘 要： | 为了得到带有异常处理结构的切片,文章从传统控制流图到系统依赖图进行了层层改进,给出了构造系统依赖图的算法,并以此为基础得到精确的程序切片。该方法可以处理因为异常结构而引起的数据流和控制流的变化,有助于实现基于异常传播的程序依赖性分析的自动处理。

A graph-based Approach of Program Slicing with Exception Handling |
| |
| Abstract: | In order to obtain the slice with the exception handling structure,this paper improved from the traditional control flow graph to the system dependence graph increasingly and presented an algorithm for constructing the system dependence graph.On the basis of the graph the precise program slicing can be gotten.The method can handle the changes of data flow and control flow caused by the exception constructs,and also provides a basis for automatic dependence analysis that contains exception constructs. |
