Module AbstractDomain.CountDomain

Domain keeping a non-negative count with a bounded maximum value. The count can be only incremented and decremented

Parameters

Signature

include WithBottom with type t = private int
include S
include NoJoin
val (<=) : lhs:t -> rhs:t -> bool

the implication relation: lhs <= rhs means lhs |- rhs

val join : t -> t -> t
val widen : prev:t -> next:t -> num_iters:int -> t
val bottom : t

The bottom value of the domain.

val is_bottom : t -> bool

Return true if this is the bottom value

top is maximum value

include WithTop with type t := t
include S
include NoJoin
val (<=) : lhs:t -> rhs:t -> bool

the implication relation: lhs <= rhs means lhs |- rhs

val join : t -> t -> t
val widen : prev:t -> next:t -> num_iters:int -> t
val top : t
val is_top : t -> bool
val increment : t -> t

bump the count by one if it is less than the max

val decrement : t -> t

descrease the count by one if it is greater than 0

val add : t -> t -> t

capped sum of two states
