Hi Everyone,

I'm working Chromium targeting Windows on ARM64 platform. As a part of 
this work I ran into an issue related to llvm in Swiftshader.

Currently fixup_aarch64_movw relocation type is not supported for COFF 
ARM64 (AArch64WinCOFFObjectWriter). As far as I see, Microsoft hasn't 
defined indicator for this relocation type. I haven't seen documented 

For AArch32 mova/movt indicators were implemented, I'm not sure but 
maybe we need to have something similar for AArch64?

Could someone give me some pointers how I could handle/fix this?

Many thanks,
