And from imcc's register allocations POV the whole coroutine stuff is a PITA, no registers are preserved, AFAIK, so a coroutines and the caller + all edges out from both do share the same registers, don't they?
They do, except that each coroutine has its own user stack so saveall and restoreall can work properly.
Yep. But due to that fact, passing arguments via stack is not possible. So a HL can only communicate with a coroutine through lexcicals or globals. And imcc will need another set of hints to figure out what's going on.
