aschwaighofer added a comment to D91098: [coro] Async coroutines: Allow more than 3 arguments in the dispatch function.

Yes, frontend is expected to emit a thunk that models the tail call to the function at the suspend point. This prevents code moving in between the tail call and return before coroutine splitting and allows for specifying how to perform the call (e.g pointer authentication).

aschwaighofer added a comment to D91098: [coro] Async coroutines: Allow more than 3 arguments in the dispatch function.

Semantically, it is not needed. But without inlining here this helper dispatch function thunk will remain at O0 because inlining is not run again.
