> Should there be some check that that symbol exists? (the current test uses the unmangled name "bar" for instance - which gives the wrong impression?)

You mean as part of the attribute validation?

> What would happen if, instead, these trampolining functions were annotated nodebug? I guess then you wouldn't have the top level one as an entry point for the user, as there would be no debug info for it?

These trampoline functions can call other functions as part of their setup, so annotating them with nodebug wouldn't guarantee that the debugger would be able to step through to the correct place. Additionally, you wouldn't be able to refer to them in LLDB expression evaluation either.
