Sorry about that.

Just to confirm this will work like nvptx, so it will report that the generic address space is available but won't generate certain generic functions (because it's identical to the private address space).

If we get round to adding proper support for `generic` atomic builtins you'd still get `generic` versions of those (with `AS0`) because there's no private address space to clash with. That's not happening right now but I thought I should make you aware.
