Module `SVA.Bitvector_Lattice`Source

include Datatype_sig.S with type t = bitvector

Sourcetype t = bitvector

Sourceval equal : t -> t -> bool

Any notion of equality is allowed, as long as it is an equivalence relation, and that if a == b, then equal a b.

Sourceval compare : t -> t -> int

compare is a total order, and should be compatible with equal.

Sourceval hash : t -> int

hash requires that equal values have the same hash.

Sourceval bottom : size:Units.In_bits.t -> t

Sourceval is_bottom : size:Units.In_bits.t -> t -> bool

Sourceval top : size:Units.In_bits.t -> t

Sourceval inter : size:Units.In_bits.t -> t -> t -> t

Sourceval join : size:Units.In_bits.t -> t -> t -> t

Sourceval pretty : size:Units.In_bits.t -> Format.formatter -> t -> unit

Sourceval widen : size:Units.In_bits.t -> previous:t -> t -> t

Sourceval includes : size:Units.In_bits.t -> t -> t -> bool

Sourceval includes_or_widen : size:Units.In_bits.t -> previous:t -> t -> bool * t

Sourceval singleton : size:Units.In_bits.t -> Z.t -> t

Sourceval is_singleton : size:Units.In_bits.t -> t -> Z.t option

Sourceval is_empty : size:Units.In_bits.t -> t -> bool

True if the binary cannot be concretized into any value.
