如何找出哪些功能没有内联 [英] How to find out which functions were NOT inlined

问题描述

有没有办法获得那些没有任何地方内联函数列表？无论是通过传递一个选项的GCC，通过检查二进制？

Is there a way to obtain a list of functions that were NOT inlined anywhere? Either by passing an option to gcc or by inspecting the binary?

编辑：我知道如何明确要求不使用gcc的内置属性noinline始终被内联函数

I know how to explicitly ask for a function not to be inlined by using gcc's builtin attribute noinline.

推荐答案

使用gcc的 -fdump树，所有并搜索转储文件内联。

Use gcc's -fdump-tree-all and search the dump files for "inline".
