摘要

程序切片是一种查找可能直接或间接影响变量值的所有语句的方法。这一概念最早由M. Weiser(1981,1984)提出。讨论了C语言中程序切片的一些问题和可能的解决方案。给出了一些基本符号和Weiser的原始算法。然后,描述了切片问题及其解决方案。例如,如何在数组和指针变量中找到正确的切片,以及如何找到对切片有影响的break、continue和goto语句。介绍了一种查找分支语句的算法。

Program slicing for C-the problems in implementation
Program slicing is a method of finding all statements that might directly or indirectly affect the values of variables. The concept was first proposed by M. Weiser (1981, 1984). Some of the problems and possible solutions of program slicing within the C language are discussed. Some basic notations and Weiser's original algorithm are presented. Then, slicing problems and solutions are described. For instance, how to find the correct slice in the presence or array and pointer variables and how to find break, continue, and goto statements that have effects on the slice. An algorithm to find the branch statements is introduced.<>
