llvm dev - May 2014 - [LLVMdev] Code generation support in llvm for windows phone

Hi,

Is there support available in llc to convert llvm bytecode to Windows Mobile
binary?
I have tried triples like arm-pc-win32 , thumbv7-window ... but the object file
generated is not getting linked to the windows native project.
Any pointers will be greatly appreciated?

Thanks,
~rajat

No - to my knowledge no one has suggested or attempted any such project/support.

I think Saleem has been working on this.  It's in a pretty early stage, so
far as I know.

As Reid mentioned, I have been working on this recently.  Just to make sure that
we are talking about the same environment, I assume that you are talking about
Windows 8 (ARM NT) rather than the Windows CE based environment.

Can you please explain what exactly you mean by “the object file generated is
not getting linked to the windows native project”.  The object file that we
generate should be pretty compatible with MSVC.  If you have specific cases
where we are generating something that is incompatible, I would be quite
interested in hearing about that.

I am talking about Windows Mobile 8 and 8.1 and not CE.
Not sure though that the Windows 8 (ARM NT) is similar to Windows Mobile 8
platform.

I used the following command to generate the obj file
    Llc.exe -mtriple=thumbv7-windows  -filetype=obj  <some_name>.bc

The object file generated in the above object doesn't get linked when I try
to link it with the windows mobile library as it fails to recognize the object
format.  ( Not a valid object file )

Hope I am clear.
