摘要
在分析异常处理结构对程序依赖性分析影响的基础上,对传统的控制流图进行改进,提出了一种新的能够描述包括异常处理结构在内的函数内和函数间的C++程序的依赖性分析模型,并给出了相应的构造算法.该方法既克服了因忽略异常处理结构对程序依赖性的影响而造成分析结果不准确的不足,又有助于实现基于异常传播的程序依赖性分析的自动处理.最后,对这种依赖性分析方法在程序切片中的应用作了进一步的探讨.
Based on analyzing the effects of exception handling constructs on dependence analysis, this paper proposes a precise and efficient representation for C＋＋ programs with exception handling constructs--improved control flow graph. It proposes a new approach to analyzing the data dependences and control de pend^nces of intra-function and inter-function in C＋＋ programs with exception handling constructs, and an efficient algorithm is also presented. This method overcomes the limitations of the previous incorrect analysis because of failing to account for the effects of exception handling constructs, and also provides a basis for automatic dependence analysis that contains exception propagation. Finally, it discusses the application of the dependence analysis method in program slicing.
