Module Frama_c_kernel.Function_Froms

Datastructures and common operations for the results of the From plugin.

module DepsOrUnassigned : sig ... end
module Memory : sig ... end
type froms = {
  1. deps_return : Memory.return;
    (*

    Dependencies for the returned value

    *)
  2. deps_table : Memory.t;
    (*

    Dependencies on all the zones modified by the function

    *)

include Datatype.S with type t = froms
include Datatype.S_no_copy with type t = froms
include Datatype.Ty with type t = froms
type t = froms
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 : 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 join : froms -> froms -> froms
val top : froms
val pretty_with_type : Cil_types.typ -> froms Pretty_utils.formatter

Display dependencies of a function, using the function's type to improve readability

val pretty_with_type_indirect : Cil_types.typ -> froms Pretty_utils.formatter

Display dependencies of a function, using the function's type to improve readability, separating direct and indirect dependencies

val outputs : froms -> Locations.Zone.t

Extract the left part of a from result, ie. the zones that are written

val inputs : ?include_self:bool -> froms -> Locations.Zone.t

Extract the right part of a from result, ie. the zones on which the written zones depend. If include_self is true, and the from is of the form x FROM y (and SELF), x is added to the result; default value is false.
