Accessing values of the ADT

val bot_of : GoblintCil.Cil.ikind -> t

val top_of : GoblintCil.Cil.ikind -> t

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 * (int64 * int64)) option

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

val of_excl_list : GoblintCil.Cil.ikind -> int_t list -> t

Creates an exclusion set from a given list of integers.

val is_excl_list : t -> bool

Checks if the element is an exclusion set.

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

Cast

include ArithIkind with type t := t

val rem : GoblintCil.Cil.ikind -> t -> t -> t

Integer remainder: x % y

Comparison operators

val lt : GoblintCil.Cil.ikind -> t -> t -> t

Less than: x < y

val gt : GoblintCil.Cil.ikind -> t -> t -> t

Greater than: x > y

val le : GoblintCil.Cil.ikind -> t -> t -> t

Less than or equal: x <= y

val ge : GoblintCil.Cil.ikind -> t -> t -> t

Greater than or equal: x >= y

val eq : GoblintCil.Cil.ikind -> t -> t -> t

Equal to: x == y

val ne : GoblintCil.Cil.ikind -> t -> t -> t

Not equal to: x != y

Bit operators

val lognot : GoblintCil.Cil.ikind -> t -> t

Bitwise not (one's complement): ~x

val logand : GoblintCil.Cil.ikind -> t -> t -> t

Bitwise and: x & y

val logor : GoblintCil.Cil.ikind -> t -> t -> t

Bitwise or: x | y

val logxor : GoblintCil.Cil.ikind -> t -> t -> t

Bitwise exclusive or: x ^ y

Logical operators

val c_lognot : GoblintCil.Cil.ikind -> t -> t

Logical not: !x
