编译器构造的语义分析阶段有哪些工具？ [英] What are the tools for semantic analysis phase of compiler construction?

问题描述

编译器的构建可以分为几个阶段，例如词法分析，语法分析，语义分析等。在词法分析中，有Lex，Flex等工具。在语法分析中有Yacc， Bison等。我很好奇语义分析阶段可以使用哪些工具？

Compiler construction can be divided into several phases such as Lexical analysis, Syntax analysis, Semantic analysis and etc. In lexical analysis, there are tools such as Lex, Flex and etc. In syntax analysis, there are tools such as Yacc, Bison, etc. I'm just curious what are the tools available for semantic analysis phase?

推荐答案

据我所知没有语言不可知的工具来执行类型检查，如果有的话，它们肯定不会普遍适用，因为许多语言的类型系统过于不同和复杂，无法由通用工具处理。

To the best of my knowledge there are no language-agnostic tools to perform type checking and if there were, they'd certainly not be generally applicable as many language's type system's are too different and complex to be handled by generalized tools.

借助范围解析，有一些工具可以为您处理的空间。例如，如果您的语言具有足够简单的作用域规则，则如果在语法中添加一些注释，则XText框架可以完全为您解决范围解析问题。在更复杂的情况下，您必须自己编写一些其他代码。

With scope resolution there's some room for tools to handle it for you. For example if your language has simple enough scoping rules, the XText framework can entirely take care of scope resolution for you if you add some annotations to your grammar. In more complex cases, you'll have to write some additional code yourself.

然后，如果编译为LLVM，则可以使用LLVM框架执行各种为您进行控制流分析。

Then, if you compile to LLVM, you can use the LLVM framework to perform all kinds of control-flow analyses for you.
