// The list of symbolic values (SVal kinds) used in the Static Analyzer.
// The distinction between `loc::` and `nonloc::` SVal namespaces is
// currently hardcoded, because it is too peculiar and explicit to be handled
// uniformly. In order to use this information, users of this file must define
// one or more of the following macros:
//
// BASIC_SVAL(Id, Parent) - for specific SVal kinds, which are
// neither in `loc::` nor in `nonloc::` namespace.
//
// ABSTRACT_SVAL(Id, Parent) - for abstract SVal classes which are
// neither in `loc::` nor in `nonloc::` namespace,
//
// LOC_SVAL(Id, Parent) - for values in `loc::` namespace.
//
// NONLOC_SVAL(Id, Parent) - for values in `nonloc::` namespace.
//
// SVAL_RANGE(Id, First, Last) - for defining range of subtypes of
// the abstract class `Id`.
