Module HoareDomain.SetEMSource

Set of Lattice.S elements with Hoare ordering. This abstracts a set by its maximal elements.

Element-wise SetDomain.S operations only observe the maximal elements.

This has a true widen using the trivial Egli-Milner connector, i.e. convergence is even guaranteed if the number of maximal elements does not converge. Otherwise Set is sufficient.

Parameters

module E : Lattice.S

Signature

include Lattice.S
include Lattice.PO
include Printable.S
Sourcetype t
Sourceval equal : t -> t -> bool
Sourceval hash : t -> int
Sourceval compare : t -> t -> int
Sourceval show : t -> string
Sourceval pretty : unit -> t -> Printable.Pretty.doc
Sourceval printXml : 'a BatInnerIO.output -> t -> unit
Sourceval name : unit -> string
Sourceval to_yojson : t -> Yojson.Safe.t
val tag : t -> int

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

Sourceval arbitrary : unit -> t QCheck.arbitrary
Sourceval relift : t -> t
Sourceval leq : t -> t -> bool
Sourceval join : t -> t -> t
Sourceval meet : t -> t -> t
Sourceval widen : t -> t -> t

widen x y assumes leq x y. Solvers guarantee this by calling widen old (join old new).

Sourceval narrow : t -> t -> t
Sourceval pretty_diff : unit -> (t * t) -> Lattice.Pretty.doc

If leq x y = false, then pretty_diff () (x, y) should explain why.

include Lattice.Bot with type t := t
Sourceval bot : unit -> t
Sourceval is_bot : t -> bool
include Lattice.Top with type t := t
Sourceval top : unit -> t
Sourceval is_top : t -> bool
Sourcetype elt = E.t
Sourceval empty : unit -> t
Sourceval is_empty : t -> bool
Sourceval mem : elt -> t -> bool
Sourceval add : elt -> t -> t
Sourceval singleton : elt -> t
Sourceval remove : elt -> t -> t

See Set.S.remove.

NB! On set abstractions this is a strong removal, i.e. all subsumed elements are also removed.

Sourceval union : t -> t -> t
Sourceval inter : t -> t -> t
Sourceval diff : t -> t -> t

See Set.S.diff.

NB! On set abstractions this is a strong removal, i.e. all subsumed elements are also removed.

Sourceval subset : t -> t -> bool

Sourceval max_elt : t -> elt

See Set.S.max_elt.

On set abstractions this chooses only a canonical element, not any subsumed element.

Sourceval choose : t -> elt

See Set.S.choose.

On set abstractions this chooses only a canonical element, not any subsumed element.
