Adding Windows on ARM Support

[Saleem Abdulrasool]

Hello,

I would like to start adding some changes into the mainline LLVM/clang trees to support Windows on ARM.  This would enable support to target the newer Windows (NT) on ARM (not Windows CE).  The support requires the Windows SDK to target the Windows on ARM environment rather than through a compatibility layer like MinGW.

I am planning on staging the frontend changes first (clang) that help with working with the SDK.  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.

Thanks!
