[llvm-dev] invalid symbol kind for ADRP relocation

[Peter Smith via llvm-dev]

That particular failure will be coming from the MC layer. Certain symbols have kinds such as VK_GOT, the ELF object writer in AArch64ELFObjectWriter.cpp has encountered a kind that it doesn't understand when trying to resolve a relocation.

I'm not sure what to say beyond that besides tracing through to find out what kind the symbol is being given and why? One potential problem is the triple "arm64-apple-macosx11.0.1-elf". As I understand it MacOS uses MachO objects and not ELF. I don't think that combination is supported or tested. It is possible that there is a MachO specific symbol kind that the ELF backend is not expecting.

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:

I have no idea where to even start looking, but it seems related to the store.
