在C / C ++中识别未使用的函数 [英] Identifying Unused Functions in C/C++
问题描述

查找死代码在大型C ++遗留应用程序中
我的项目有很多C源文件每个都有很多全局函数。很多这些都不再被任何调用者引用。是否有一个简单的方法来识别这些函数哪些没有被任何人引用?
My project has a lots of C source files each with a lots of global functions. Many of these are no longer referenced by any caller at all. Is there a simple way to identify which of these functions are not referenced by anyone at all?
VC生成的映射文件似乎是有用的。但我不确定如何/当一个函数名称在地图文件中列出。
The map file generated by VC seems to be useful. But I am not sure exactly how/when a function name is listed in the map file.
