Frama-C API - HCE

Datatype + utilities functions for hashconsed exprsessions.

include Frama_c_kernel.Datatype.S
include Frama_c_kernel.Datatype.S_no_copy
include Frama_c_kernel.Datatype.Ty
type t
val datatype_name : string

Unique name of the datatype.

val datatype_descr : t Frama_c_kernel.Descr.t

Datatype descriptor.

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 : (Frama_c_kernel.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.

module Set : Frama_c_kernel.Datatype.Set with type elt = t
module Map : Frama_c_kernel.Datatype.Map with type key = t
val id : t -> int

Conversions between type t and Cil lvalues and expressions.

val of_lval : Eva_ast.lval -> t
val of_exp : Eva_ast.exp -> t
val get : t -> unhashconsed_exprs
val to_exp : t -> Eva_ast.exp
val to_lval : t -> Eva_ast.lval option
val is_lval : t -> bool
val replace : kill_type -> late:Eva_ast.lval -> heir:Eva_ast.exp -> t -> t

Replaces all occurrences of the lvalue late by the expression heir.
