AlgorithmInvokeCall does not report variable usage properly

[hiker]

While implementing a trans_alg function, I tried running the VariablesAccessInfo. But the actual invoke did not add its parameters at all, it only reported the kernel types, e.g.:

            call invoke(count_neighbours(neighbours, current),   &
                        compute_born(born, current, neighbours), &
                        compute_die(die, current, neighbours),   &
                        combine(current, die, born),             &
                        name="compute"    )

would report count_neighbours, compute_born, ... - but not the actual parameters neighbours, born etc.

I even tried calling lower_to_language_level, and it didn't help either.

I believe all we need to do is add a custom reference_accesses function for the AlgorithmInvokeCall (?)
