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 anywhere. For AArch32
