Disassembly display in Visual Studio

Question

I'm using VS  2010 Express and I'm trying to get my compiled source code to be displayed in assembly. I could easily do this when using VS 6 but can't see how to do this in VS 2010. I want to see each line of my source code with the coresponding assembly line below it. For example:

++x;                                        // source code

mov ax, [0b3456743];               // assembly representation

inc ax;

mov [0b3456743], ax;

 

Thank you for any help!

 

Answer 1

While debugging, go to Debug->Windows->Disassembly. The shortcut for this on my system is Ctrl+Alt+D.

Thanks for your reply, but I tried that and there is no window for disassembly. Are you using Visual Studio 2010 Express? I wonder if the express edition has that feature. The way you stated worked on VS 6 (introductory edition) but not with VS 2010.

I am not sure if this works in VS 2010 Express, but you can have the compiler output assembler output with Assembly, Machine Code, and Source:

1.) Right click on the Project Name in the Solution Explorer.

2.) Click on the "Properties" menu item.

3.) Navigate to "Configuration Properties -> C/C++ -> Output Files".

4.) Set the "Assembler Output" to "Assembly, Machine Code and Source (/FAcs)"

5.) Make sure the "ASM List Location" is set (my system defaulted to "$(IntDir)").

If the above options are not available, then try adding the following to the "Additional Options" under "Configuration Properties -> C/C++ -> Command Line":

/FAcs /Fa"Debug\"

 

The listing files will have an extension of .cod

 

For more information see the following MSDN library page:

NOTE: The file is pretty big, I would recommend searching for a comment that is near the code you are wanting to investigate.

Thanks David! That was it. And thanks for pointing out the .cod extention. Your a gentelman and a scholar.

Answer 5

Can you please help me because I have the same problem. I made all the settings listed but do not know where to find the .cod listing files

Answer 6

I made all the settings listed but do not know where to find the .cod listing files

In the same project directory as where the .obj files are created.

Note that the extension isn't always .cod - as described
in the documentation it may be .asm, depending on which
option you used.

sorry but I am not understanding at all where are these files.

Enable Expert settings in VS 2010 Express. Tools > Settings > Expert settings. Then, new window types appear under Debug > Windows (for example, Disassembly).
