val pretty : Stdlib.Format.formatter -> t_prop -> unit

optionally init env with user logic variables

val add_assigns : t_env -> WpPropId.assigns_info -> t_prop -> t_prop
val use_assigns : t_env -> WpPropId.prop_id option -> WpPropId.assigns_desc -> t_prop -> t_prop

use_assigns env hid kind assgn goal performs the havoc on the goal. * hid should be None iff assgn is WritesAny, * and tied to the corresponding identified_property otherwise.

val has_init : t_env -> bool
val loop_entry : t_prop -> t_prop
val loop_step : t_prop -> t_prop

val close : t_env -> t_prop -> t_prop
val build_prop_of_from : t_env -> WpPropId.pred_info list -> t_prop -> t_prop

build p => alpha(p) for functional dependencies verification.
