//
// The list of symbolic values (SVal kinds and sub-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 sub-kinds, which are
// neither in loc:: nor in nonloc:: namespace; these classes occupy
// their own base kind IdKind.
//
// ABSTRACT_SVAL(Id, Parent) - for abstract SVal classes which are
// neither in loc:: nor in nonloc:: namespace,
//
// ABSTRACT_SVAL_WITH_KIND(Id, Parent) - for SVal classes which are also
// neither in loc:: nor in nonloc:: namespace, but occupy a whole base kind
// identifier IdKind, much like BASIC_SVALs.
//
// LOC_SVAL(Id, Parent) - for values in loc:: namespace, which occupy a sub-kind
// loc::IdKind.
//
// NONLOC_SVAL(Id, Parent) - for values in nonloc:: namespace, which occupy a
// sub-kind nonloc::IdKind.
