Frama-C API - Consolidation

Consolidation of a property status according to the (consolidated) status of the hypotheses of the property.

who do the job and, for each of them, who find which issues.

type consolidated_status = private
  1. | Never_tried
    (*

    Nobody tries to verify the property. The argument is for internal use only

    *)
  2. | Considered_valid
    (*

    Nobody succeeds to verify the property, but it is expected to be verified by another way (manual review, ...)

    *)
  3. | Valid of Emitter.Usable_emitter.Set.t
    (*

    The verification of this property is fully done. No work to do anymore for this property. The argument is the emitters who did the job.

    *)
  4. | Valid_under_hyp of pending
    (*

    The verification of this property is locally done, but it remains properties to verify in order to close the work.

    *)
  5. | Unknown of pending
    (*

    The verification of this property is not finished: the property itself remains to verify and it may also remain other pending properties. NB: the pendings contains the property itself.

    *)
  6. | Invalid of Emitter.Usable_emitter.Set.t
    (*

    The verification of this property is fully done. All its hypotheses have been verified, but it is false: that is a true bug.

    *)
  7. | Invalid_under_hyp of pending
    (*

    This property is locally false, but it remains properties to verify in order to be sure that is a bug.

    *)
  8. | Invalid_but_dead of pending
    (*

    This property is locally false, but there is other bugs in hypotheses

    *)
  9. | Valid_but_dead of pending
    (*

    This property is locally true, but there is bugs in hypotheses

    *)
  10. | Unknown_but_dead of pending
    (*

    This property is locally unknown, but there is other bugs in hypotheses

    *)
  11. | Inconsistent of string
    (*

    Inconsistency detected when computing the consolidated status. The string explains what is the issue for the end-user.

    *)
include Datatype.S with type t = consolidated_status
include Datatype.S_no_copy with type t = consolidated_status
include Datatype.Ty with type t = consolidated_status
val ty : t Type.t
val name : string

Unique name of the datatype.

val descr : t Descr.t

Datatype descriptor.

val packed_descr : Structural_descr.pack

Packed version of the descriptor.

val reprs : t list

List of representants of the descriptor.

val equal : t -> t -> bool

Equality: same spec than Stdlib.(=).

val compare : t -> t -> int

Comparison: same spec than Stdlib.compare.

val hash : t -> int

Hash function: same spec than Hashtbl.hash.

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

Pretty print each value in an user-friendly way.

val mem_project : (Project_skeleton.t -> bool) -> t -> bool

mem_project f x must return true iff there is a value p of type Project.t in x such that f p returns true.

val copy : t -> t

Deep copy: no possible sharing between x and copy x.

val get : Property.t -> t
val get_conjunction : Property.t list -> t
