查看编译器扩展代码 - C++ [英] Viewing compiler expanded code - C++

问题描述

我了解到编译器会在编译时扩展宏.模板也在编译时展开.有没有办法看到这个扩展的代码?我正在使用 Visual Studio 2008 进行编译.

I learned that compiler will expand macros while compiling. Templates are also expanded at the compile time. Is there any way to see this expanded code? I am compiling using Visual Studio 2008.

有什么想法吗?

推荐答案

VC++ 编译器 (cl.exe) 支持一些命令行开关:

The VC++ compiler (cl.exe) supports a few command line switches for this:

/E preprocess to stdout
/P preprocess to file
/EP preproscess to stdout with no #lines

可以在项目属性中添加其他命令行开关.在我的版本(VC2005)中，配置选项 -> C/C++ -> 命令行 -> 附加选项

Additional command-line switches can be added in your project properties. In my version (VC2005), Configuration Options -> C/C++ -> Command Line -> Additional Options
