val array_clean_new_index : bool -> Exp.t -> Exp.t
(** This function should be used before adding a new
    index to Earray. The [exp] is the newly created
    index. This function "cleans" [exp] according to whether it is the
    footprint or current part of the prop.
    The function faults in the re - execution mode, as an internal check of the tool. *)

val abstract_array_check : Tenv.t -> Prop.normal Prop.t -> Prop.normal Prop.t
(** Apply array abstraction and check the result *)

val array_abstraction_performed : bool ref
