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