Exp (goblint.Mval.Exp)

type idx = GoblintCil.exp

Type of indices in mvalue offset.

type t = GoblintCil.varinfo * idx Offset.t

include Printable.S with type t := t

val equal : t -> t -> bool

val hash : t -> int

val compare : t -> t -> int

val show : t -> string

val pretty : unit -> t -> Printable.Pretty.doc

val printXml : 'a BatInnerIO.output -> t -> unit

val name : unit -> string

val to_yojson : t -> Yojson.Safe.t

val tag : t -> int

Unique ID, given by HConsed, for context identification in witness

val arbitrary : unit -> t QCheck.arbitrary

val relift : t -> t

val is_definite : t -> bool

Whether offset of mvalue has only definite integer indexing (and fields).

val add_offset : t -> idx Offset.t -> t

add_offset m o appends o to m.

val prefix : t -> t -> idx Offset.t option

prefix m1 m2 checks if m1 is a prefix of m2.

returns
Some o if it is (such that the variables are equal and add_offset m1 o = m2), None if it is not.

val to_cil : t -> GoblintCil.lval

Convert to CIL lvalue.

val to_cil_exp : t -> GoblintCil.exp

Convert to CIL lvalue expression.

val type_of : t -> GoblintCil.typ

Type of mvalue.
