扫描并分析c代码 [英] scan and analyse a c code

问题描述

如何扫描完整的c代码并获取贵重物品和函数之间的关系？结果打印成表？

解决方案

通过编写大量代码，基本上是半个C编译器。

嗯......你可以写一个程序来做我想的。问题在于你本质上是在写一个C编译器的好部分（解析器？lexer？）。请注意，在您运行分析器之前需要对代码进行预处理，否则宏可能会给您带来麻烦。

Hello叶千



你可以开始这里 [ ^ ]。这是一个基于python的c-parser，看起来很有前途。但是我没有使用过它。



周围可能有几个C解析器（肯定有几个yacc语法，例如http://www.lysator.liu.se/c/ANSI-C-grammar-y.html [ ^ ]）。与C ++，C＃等相比，C语言解析起来并不复杂。



真正的挑战从你想要对解析的AST执行的分析开始。

我不清楚你想从扫描中提取到底是什么。



干杯

How can I scan a complete c code and get the relations between valuables and functions?Result printed to be a table?

解决方案

By writing a LOT of code, essentially half a C compiler.

Ummm... you could write a program to do that I suppose. The problem being that you would essentially be writing a good portion (parser? lexer?) of a C compiler. Beware that the code would need to be pre-processed before you run your analyzer on it or macros would probably cause you trouble.

Hello 叶千

you might start here[^]. This is a python based c-parser that looks promising to me. I have not used it, though.

There might be several C parsers around (for sure several yacc grammars, e.g. http://www.lysator.liu.se/c/ANSI-C-grammar-y.html[^]). The C language is not so complex to parse compared to C++, C#, etc.

The real challenge starts with the analysis you want to perform on the parsed AST.
It is not clear to me what exactly you want to extract from the "scan".
