Module AddressSet.Addr

type t = AddressBase(Mval).t =
  1. | Addr of Mval.t
    (*

    Pointer to mvalue.

    *)
  2. | NullPtr
    (*

    NULL pointer.

    *)
  3. | UnknownPtr
    (*

    Unknown pointer. Could point to globals, heap and escaped variables.

    *)
  4. | StrPtr of StringDomain.t
    (*

    String literal pointer. StrPtr None abstracts any string pointer

    *)
