是否可以强制不内联函数?

Is it possible to force a function not to be inlined?(是否可以强制不内联函数?)

问题描述

我想强制一个小函数不被编译为内联函数，即使它很简单.我认为这对于调试目的很有用.有什么关键字可以做到这一点吗?

I want to force a little function not to be compiled as inline function even if it's very simple. I think this is useful for debug purpose. Is there any keyword to do this?

推荐答案

在 Visual Studio 2010 中，__declspec(noinline) 告诉编译器永远不要内联特定的成员函数，例如:

In Visual Studio 2010, __declspec(noinline) tells the compiler to never inline a particular member function, for instance:

class X {
     __declspec(noinline) int member_func() {
          return 0; 
     }
};

此外，当使用 /clr 编译时，具有安全属性的函数永远不会被内联(同样，这是 VS 2010 特有的).

edit: Additionally, when compiling with /clr, functions with security attributes never get inlined (again, this is specific to VS 2010).

不过，我认为它在调试中根本没有用.

I don't think it will prove at all useful at debugging, though.
