查找“死代码”在大型C ++遗留应用程序中 [英] Finding "dead code" in a large C++ legacy application

问题描述

我目前正在开发一个大型和旧的C ++应用程序，在我之前有很多开发人员。在项目中有很多死代码，任何人不再使用的类和函数。

I'm currently working on a large and old C++ application that has had many developers before me. There is a lot of "dead code" in the project, classes and functions that aren't used by anyone anymore.

C ++有哪些工具可用于分析大型代码库以检测和重构死代码？注意：我不是说gcov这样的测试覆盖工具。

What tools are available for C++ to make a analysis of large code base to detect and refactor dead code? Note: I'm not talking about test coverage tool like gcov.

如何在你的项目中找到死代码？

How do you find dead code in your project?

推荐答案

您需要使用静态分析工具

• StackOverflow：有哪些开源C ++静态分析工具可用？


• StackOverflow： C ++静态代码分析工具


• 维基百科：静态代码工具列表分析

• StackOverflow: What open source C++ static analysis tools are available?
• StackOverflow: C++ static code analysis tool on Windows
• Wikipedia: List of tools for static code analysis

我遇到的主要问题是你必须小心，不要使用任何库从你不控制/有的地方。如果你从一个类中删除一个函数，通过引用你的项目中的库，你可以破坏你不知道使用的代码。

The main gotcha I've run into is that you have to be careful that any libraries aren't used from somewhere that you don't control/have. If you delete a function from a class that gets used by referencing a library in your project you can break something that you didn't know used the code.
