Module `HoareDomain.Set`Source

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 extrapolation heuristics instead of a true widen, i.e. convergence is only guaranteed if the number of maximal elements converges. Otherwise use SetEM.

Parameters

module B : Lattice.S

Signature

include SetDomain.S with type elt = B.t

include Lattice.S

include Lattice.PO

include Printable.S

type 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.

Sourceval bot : unit -> t

Sourceval is_bot : t -> bool

Sourceval top : unit -> t

Sourceval is_top : t -> bool

type elt = B.t

Sourceval empty : unit -> t

val 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.

See Set.S.filter.

On set abstractions this filters only canonical elements, not all subsumed elements.

Sourceval partition : (elt -> bool) -> t -> t * t

See Set.S.partition.

On set abstractions this partitions only canonical elements, not all subsumed elements.

Sourceval cardinal : t -> int

See Set.S.cardinal.

On set abstractions this counts only canonical elements, not all subsumed elements.

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.
