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

...isting and the new ABI. For Mips N32, code and state in MCELFObjectTargetWriter seems to take care of mapping the relocation values and the ELF e_flags bit EF_MIPS_ABI_ON32 is set. I'm trying to implement the AArch64 ILP32 ELF ABI.Ideally, I'd like to be able to create a modified version of AArch64ELFObjectWriter so that its GerRelocType method can choose which relocation encoding to use based upon what was specified on the command line. Should I make up a new OSABI enum value? Do some kind of manipulation of the Triple environment field to set it based upon the value of "-mabi="? ARM64 ELF  Ref...

hi, does anyone know how to resolve this? It's a very simple IR file (below), fails with: LLVM ERROR: invalid symbol kind for ADRP relocation PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash backtrace. Stack dump: 0. Program arguments: \p\llvm-project-bin32\RelWithDebInfo\bin\llc.exe -O0 debug_output(1).ll -filetype=obj #0 0x01522349
