Should I add intrinsics to write my own automatic reference counting passes?
...om intrinsics to function call
6. full optimization passes
I think about having the following intrinsics:
ptr = cast_untyped_to_nonshared(ptr) // e.g. used after allocation
ptr = cast_to_shared_irreversible(ptr) // basically a gateway to other
threads
nonhared_acquire(ptr)
nonshared_release(ptr)
shared_acquire(ptr)
shared_release(ptr)
I also want weak_ptr at a later stage, but leave it out for now to keep
the complexity manageble.
Is this idea completely unreasonable?

The main problem for this sort of optimization is that it is difficult
to do on...
