Right now Im planning on using IA-64 ABI (which is unfortunately incompatible with msvcrp).  Longer term, I think that getting C++ MS ABI on ARM would be incredible.

The support requires the Windows SDK to target the Windows on ARM environment rather than through a compatibility layer like MinGW.

I would follow this up with some support changes in LLVM to support clang’s targeting of the new environment, and finish it off with the target specific changes in LLVM.  If anyone has a better approach to staging this, I am happy to discuss that.
