erichkeane added a comment. Yeah, I think the diagnostics result of this attribute are unacceptable. I understand the goal here, but I suspect the more ergonomic (albeit, perhaps surprising) is a `[[should_tail]]` attribute sort of thing: a tail-hint where we do 'best effort with no promises', and make no guarantees that we're going to tail it. I'm sure this would require more work in the backends + require an additional IR tag, but even that seems difficult to use properly.
Could we instead encode the platform specific tail-call rules in Sema? We definitely have attributes that differ in behavior between platforms, and this seems like a perfect candidate.
