9// The list of symbolic values (SVal kinds and sub-kinds) used in the Static
10// Analyzer. The distinction between loc:: and nonloc:: SVal namespaces is
11// currently hardcoded, because it is too peculiar and explicit to be handled
12// uniformly. In order to use this information, users of this file must define
13// one or more of the following macros:
14//
15// BASIC_SVAL(Id, Parent) - for specific SVal sub-kinds, which are
16// neither in loc:: nor in nonloc:: namespace; these classes occupy
17// their own base kind IdKind.
18//
19// ABSTRACT_SVAL(Id, Parent) - for abstract SVal classes which are
20// neither in loc:: nor in nonloc:: namespace,
21//
22// ABSTRACT_SVAL_WITH_KIND(Id, Parent) - for SVal classes which are also
23// neither in loc:: nor in nonloc:: namespace, but occupy a whole base kind
24// identifier IdKind, much like BASIC_SVALs.
25//
26// LOC_SVAL(Id, Parent) - for values in loc:: namespace, which occupy a sub-kind
27// loc::IdKind.
28//
29// NONLOC_SVAL(Id, Parent) - for values in nonloc:: namespace, which occupy a
30// sub-kind nonloc::IdKind.
