Accessing values of the ADT

val to_int : t -> int_t option

Return a single integer value if the value is a known constant, otherwise * don't return anything.

val equal_to : int_t -> t -> [ `Eq | `Neq | `Top ]
val to_bool : t -> bool option

Give a boolean interpretation of an abstract value if possible, otherwise * don't return anything.

val to_excl_list : t -> (int_t list * (int * int)) option

Gives a list representation of the excluded values from included range of bits if possible.

val to_incl_list : t -> int_t list option

Gives a list representation of the included values if possible.

val maximal : t -> int_t option
val minimal : t -> int_t option
