摘要

给出了表意程序切片的一个原始的理论定义。程序切片是一种完全基于控制和数据流信息的自动程序分解方法。表意切片利用特定编程语言的功能语义,并定义各种域和它们之间的适当映射。为每个语言结构定义转换,并以数学和系统的方式应用于程序。结果表明,程序片可以用表意方式构造,其直接结果可以精确而简单地指定。

Denotational program slicing
An original, theoretical definition of denotational program slicing is presented. Program slicing is a method for automatic program decomposition that is based exclusively on control and data-flow information. Denotational slicing makes use of the functional semantics of a particular programming language and defines the various domains and appropriate mappings between them. Transformations are defined for each of the language constructs and applied to programs in a mathematical and systematic fashion. It is shown that program slices can be constructed denotationally and as a direct result can be specified precisely and simply.<>
