是否有一个可移植的等同于DebugBreak（）/ __ debugbreak？

问题描述

在MSVC中，或导致调试器中断。在x86它相当于写_asm int 3，在x64它是不同的东西。当用gcc（或任何其他标准编译器）编译时，我也想做一个调试器。有平台独立的功能还是内在的？我看到了，但它没有

Sidenote：我主要想实现ASSERT，我理解我可以使用assert（），但我也想写DEBUG_BREAK

解决方案

基于#ifdef定义一个条件宏如何根据当前的架构或平台。

像：

  #ifdef _MSC_VER 
 #define DEBUG_BREAK __debugbreak（）
 #else 
 ... 
 #endif 
  

这将由预处理器根据编译代码的平台扩展正确的调试器断点指令。这样，您就可以在代码中始终使用 DEBUG_BREAK 。

In MSVC, DebugBreak() or __debugbreak cause a debugger to break. On x86 it is equivalent to writing "_asm int 3", on x64 it is something different. When compiling with gcc (or any other standard compiler) I want to do a break into debugger, too. Is there a platform independent function or intrinsic? I saw the XCode question about that, but it doesn't seem portable enough.

Sidenote: I mainly want to implement ASSERT with that, and I understand I can use assert() for that, but I also want to write DEBUG_BREAK or something into the code.

解决方案

What about defining a conditional macro based on #ifdef that expands to different constructs based on the current architecture or platform.

Something like:

#ifdef _MSC_VER
#define DEBUG_BREAK __debugbreak()
#else
...
#endif

This would be expanded by the preprocessor the correct debugger break instruction based on the platform where the code is compiled. This way you always use DEBUG_BREAK in your code.
