I provided this more expedient patch exactly because I suspected that finding out the answers to those questions and implementing the missing logic was going to be non-trivial. For me, this was initially just a weekend patch to make stack traces work properly on macOS, as contributing to LLVM's Darwin support is a bit outside of my current professional scope. Still, if no one else steps up in the meantime I expect I'll eventually get around to doing that investigation and proper implementation, but it might take a while. I'll reference any follow-up patches or investigation results here.
