val pp : IStdlib.PrettyPrintable.F.formatter -> t -> unit

val leq : 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

val compare : t -> t -> int
val bot : t
val make_c : AbsLoc.Allocsite.t -> offset:Itv.t -> size:Itv.t -> stride:Itv.t -> t: Make an array block for C

val make_java : AbsLoc.Allocsite.t -> length:Itv.t -> t: Make an array block for Java

val unknown : t
val get_pow_loc : t -> AbsLoc.PowLoc.t: Return all allocsites as PowLoc.t

val is_bot : t -> bool
val is_symbolic : t -> bool: Check if there is a symbolic integer value in its offset or size

val lift_cmp_itv : (Itv.t -> Itv.t -> Boolean.t) -> Boolean.EqualOrder.t -> t -> t -> Boolean.t: Lift a comparison of Itv.t and Loc.t to that of t. The comparison for Itv.t is used for integer values such as offset and size, and the comparison for Loc.t is used for allocsites.

val transform_length : f:(Itv.t -> Itv.t) -> t -> t: Apply f to all sizes

val prune_binop : IR.Binop.t -> t -> t -> t: prune_binop bop x y returns a pruned value of x by bop and y.

val prune_eq : t -> t -> t: prune_eq x y returns a pruned value of x by == y.

val prune_ne : t -> t -> t: prune_ne x y returns a pruned value of x by != y.

val prune_offset_le_size : t -> t: Prune offset by offset <= size

val minus_offset : t -> Itv.t -> t
val plus_offset : t -> Itv.t -> t
val diff : t -> t -> Itv.t: Return difference of offsets between given array blocks

val normalize : t -> t: Normalize all interval values such as offset and size in it. Thus, if an interval value is invalid, the interval value is replaced with bottom.

val subst : t -> Bounds.Bound.eval_sym -> AbsLoc.PowLoc.eval_locpath -> AbsLoc.PowLoc.t * t: Substitute symbolic abstract locations and symbolic interval value in the array block. eval_sym is to get substituted interval values and eval_locpath is to get substituted abstract locaion values. It also returns a set of abstract locations containing non-allocsite locations from the substitution results. Since the key of ArrayBlk.t is AbsLoc.Allocsite.t, they cannot be written in this domain.

val set_length : Itv.t -> t -> t
val set_offset : Itv.t -> t -> t
val set_stride : Z.t -> t -> t
val get_symbols : t -> BO.Symb.SymbolSet.t: Return all symbols for integer values in it

val get_offset : ?⁠cost_mode:bool -> t -> Itv.t: Return offset of the array block. If cost_mode is true, it returns a conservative (bigger than correct one), but not correct offset results.

val get_size : ?⁠cost_mode:bool -> t -> Itv.t: Return size of the array block. If cost_mode is true, it returns a conservative (bigger than correct one), but not correct size results.
