I don't understand is why PROPerties are not associated with TODO_ functions in a way that if a pass don't have the properties it requires, it can call the appropriate TODO_ function. That way, if some pass needs PROP_alias but none has triggered TODO_rebuild_alias, then that pass calls TODO_rebuild_alias by itself. That way, if no pass requires alias information, then no pass ever calls TODO_rebuild_alias. Not sure that I am not talking nonsense, but this seems a far better approach that just ICEing because a certain combination of passes cannot work together. Anyway, this surely is far more complex that I am making it out to be... sorry. Cheers, Manuel.
