[cfe-dev] Clang-Cl - support for the FAcs flag?

[via cfe-dev]

I don't think I'm good enough to make a patch for clang.
Is there at least a way to have the line numbers of the source code in the 
assembly output?

But patches are of course gladly accepted, if you want to give it a try 
yourself :-)

Other ways to get what you want:
* If you use vim, whodis (https://github.com/sgraham/whodis) can show the 
assembly of the current function and it color-codes which parts of the 
function become which assembly. It works reasonably well. I haven't tried 
it on Windows yet, but in a chrome/win cross build on linux it worked 
well.
* Ideally we'd add clang-cl support to godbolt.org. I looked at this for a 
tiny bit a few months ago (
https://github.com/mattgodbolt/compiler-explorer/issues/204) but got 
distracted (and I'm not super likely to get re-tracted…uh…back-on-track 
soon – so this would be a cool project for someone too)

I don't think there are any plans to add it. We don't have support for the 
equivalent GCC flags yet either (-Wa,-adhln, I think?), so this isn't just 
a matter of hooking things up. The feature would need to be implemented 
from scratch.

Hello Clang-Dev-List-People, 

I use clang-cl integrated to Visual Studio to compile my projects. This is 
working fine. I wanted to ask, if there are plans for supporting the /FAcs 
flag of the visual studio compiler? Or at least is there a work around? 

For those how doesn't know the flag: 
It generates assembly output, but also mixes the C/C++ source code as 
comments into it. This really helps to find points of interest. 

Kind regards
