val mem_base : Base.t -> t -> bool
mem_base b m returns true if b is associated to something or topified in t, and false otherwise.

val intersects : t -> t -> bool
val valid_intersects : t -> t -> bool
Assuming that z1 and z2 only contain valid bases, valid_intersects z1 z2 returns true iff z1 and z2 have a valid intersection.

Folding


val filter_base : (Base.t -> bool) -> t -> t
filter_base can't raise Error_Top since it filters bases of Top bases. Note: the filter may give an over-approximation (in the case Top Top).
val fold_bases : (Base.t -> 'a -> 'a) -> t -> 'a -> 'a
fold_bases folds also bases of Top bases.
Raises Error_Top in the case Top Top.
val fold_i : (Base.t -> Lattice_Interval_Set.Int_Intervals.t -> 'a -> 'a) -> t -> 'a -> 'a
fold_i f l acc folds l by base.
Raises Error_Top in the cases Top Top, Top bases.
val fold_topset_ok : (Base.t -> Lattice_Interval_Set.Int_Intervals.t -> 'a -> 'a) -> t -> 'a -> 'a
fold_i f l acc folds l by base.
Raises Error_Top in the case Top Top.

Lmap_bitwise utilities



The functions default and default_all are intended to be called by the functor Lmap_bitwise.
val default : Base.t -> Abstract_interp.Int.t -> Abstract_interp.Int.t -> t
val defaultall : Base.t -> t
val shape : map_t ->
Lattice_Interval_Set.Int_Intervals.t Hptmap.Shape(Base.Base).t
