With 3.9, llvm-link tells me 'invalid subroutine type ref' when linking the two code pieces below, and I don't quite understand why. It looks like it merges the debug information with the custom metadata. I've filed a ticket already [1] but as I'm not sure if this is indeed a bug or if I'm misunderstanding something, I thought I'd ask here. Any ideas? Thanks, Robin
