10//  This file defines the AST type info database. Each type node is
11//  enumerated by providing its name (e.g., "Builtin" or "Enum") and
12//  base class (e.g., "Type" or "TagType"). Depending on where in the
13//  abstract syntax tree the type will show up, the enumeration uses
14//  one of four different macros:
15//
16//    TYPE(Class, Base) - A type that can show up anywhere in the AST,
17//    and might be dependent, canonical, or non-canonical. All clients
18//    will need to understand these types.
19//
20//    ABSTRACT_TYPE(Class, Base) - An abstract class that shows up in
21//    the type hierarchy but has no concrete instances.
22//
23//    NON_CANONICAL_TYPE(Class, Base) - A type that can show up
24//    anywhere in the AST but will never be a part of a canonical
25//    type. Clients that only need to deal with canonical types
26//    (ignoring, e.g., typedefs and other type alises used for
27//    pretty-printing) can ignore these types.
28//
29//    DEPENDENT_TYPE(Class, Base) - A type that will only show up
30//    within a C++ template that has not been instantiated, e.g., a
31//    type that is always dependent. Clients that do not need to deal
32//    with uninstantiated C++ templates can ignore these types.
