摘要
提出了一种基于分层思想的,并且无需构造具体语法树的变量类型提取方法。目的是为高级语言的类型信息的提取提供一般方法,从而降低类型系统实现的难度以及产生程序错误的可能性,并且简化高级语言的中间表示,便于后端的代码生成和优化。
This paper introduced a kind of variable type collecting method, which is based on layered thoughtway and abstract syntax tree. Our purpose is to supply a common method for type information collection of high-level programming languages, so that we can lower the difficulty of the implemention of type system and the possibility of occurence of the program errors; simplify the intermediate presentation of high-level programming language, so that we can do code generation and optimization conveniently.
