Can We Feed the Output of MSVC++ Assembly Listing to MASM32

[msqweasm]

(Originally wrongly placed in another subforum .  I guess here is a better place for it)

In MSVC++ 2008, we can use the /FA switch to create an assembly listing file for the C++ code.  Can we edit this file directly and assemble it using say MASM32 or any other tools available to MSVC++ 2008 (say ml.exe)?  I mean, is this file created for human reading only or is it just part of the compiler output used internally for the assembler?

The way I assemble the listing file is like this:

In the VC++ 2008 Tools menu->External Tool, create a new item to ml.exe:

Command:C:\Program Files\Microsoft Visual Studio 9.0\VC\bin\ml.exe
Arguments:  /c $(ItemPath)
Initial Directory: $(targetdir)
Use Output Window: (selected)

Then open the .asm file in the IDE and click Tools->"the Newly Created Menu item for ml.exe".  This should invoke the ml.exe with the asm file as argument.

I have tried this myself with VC++ 2008.  When compiled to the Debug version (listing file generated in the Debug dir), it has errors:

MASM doesn't like these stuff:

The Release version works fine.

Why are there errors for the Debug version?

ML doesn't like the dot. Perhaps OPTION DOTNAME in one of the first lines could help, although afaik it is meant for leading dots.

[msqweasm]

No luck with OPTION DOTNAME (btw, is my modification correct?)

Your modification is correct, but no surprise that it didn't work. Strange that ml chokes over that, one should think it must digest a listing generated by a C compiler... ::)

Turn off all RTCs (running-time checks).
so generated asm-listing is acceptable to MASM
