在VC ++中进入MACRO [英] stepping into MACRO in VC++

问题描述

我正在调试一个源代码，它有很多大的#define的MACRO例程。
我很感兴趣的进入他们，但我想，VC ++不允许step-in功能...所以，

• 我将它们转换为函数，但这对我来说变得很难。

有没有办法进入MACRO例程？特别是在VC ++中？

PS：如果gcc编译器支持步进到MACRO，我可以将整个代码移植到gcc中

解决方案

除了上面所有的正确答案：我通常做的是显示混合显示（C +程序集）。这表明真正发生了什么。即使你不是底层程序集的专家，它给出一个想法发生了什么（即它是一个简单的替换或复杂的循环）。它还将提供额外的机会，以便步入功能。例如，如果你的宏是

  #define foo（a）i ++; foo_func（a，i）
  

您的调试器将显示类似
循环和使用什么类型的变量。您可以使用宏定义作为参考来了解它。

  00411454 mov dword ptr [j]，eax 
 00411457 cmp dword ptr [j]，0Ah 
 0041145B jge wmain + 58h（411478h）
 {
 foo（j）; 
 0041145D mov eax，dword ptr [i] 
 00411460 add eax，1 
 00411463 mov dword ptr [i]，eax 
 00411466 mov eax，dword ptr [i] 
 00411469 push eax 
 0041146A mov ecx，dword ptr [j] 
 0041146D push ecx 
 0041146E调用foo_func（411028h）
 00411473添加esp，8 
} 
  

这给出了一个线索，变量i和j用于调用函数foo_func。

如果使用Visual C ++，它将允许你从宏（F11）调用函数;不是个别声明。

I am debugging a source code that has a lot of big #define'd MACRO routines. I am interesting in stepping into them, but I guess, VC++ does not allow step-in functionality ... so,

• I am converting them into functions, but this is becoming hard for me

Is there a way to step into MACRO routines? especially in VC++?

PS: I can port the whole code into gcc, if gcc compiler supports stepping into MACRO

解决方案

In addition to all correct answers above: what I usually do is to show mixed display (C+assembly). This shows what really happens. Even if you are no expert in the underlying assembly, it gives an idea what happens (i.e. is it a trivial replacement or a complex loop). Also it will provide additional opportunities to step into functions. For instance, if your macro is

#define foo(a) i++;foo_func(a,i)

your debugger will show something like looping and what kind of variables are used). You can use the macro definition as a reference to understand it.

00411454  mov         dword ptr [j],eax 
00411457  cmp         dword ptr [j],0Ah 
0041145B  jge         wmain+58h (411478h) 
    {
    	foo(j);
0041145D  mov         eax,dword ptr [i] 
00411460  add         eax,1 
00411463  mov         dword ptr [i],eax 
00411466  mov         eax,dword ptr [i] 
00411469  push        eax  
0041146A  mov         ecx,dword ptr [j] 
0041146D  push        ecx  
0041146E  call        foo_func (411028h) 
00411473  add         esp,8 
    }

This gives a clue that variables i and j are used to call function foo_func.

If you use Visual C++, it will allow you to step into functions called from a macro (F11); not individual statements though.
