// BuiltinType::Id is the enumerator defining the type.

// Context.SingletonId is the global singleton of this type. Some global

// BUILTIN_TYPE(Id, SingletonId) - A builtin type that has not been

// SIGNED_TYPE(Id, SingletonId) - A signed integral type.

// UNSIGNED_TYPE(Id, SingletonId) - An unsigned integral type.
//
// FLOATING_TYPE(Id, SingletonId) - A floating-point type.

// PLACEHOLDER_TYPE(Id, SingletonId) - A placeholder type. Placeholder
// types are used to perform context-sensitive checking of specific

//
// SHARED_SINGLETON_TYPE(Expansion) - The given expansion corresponds

BUILTIN_TYPE(NullPtr, NullPtrTy)
// The primitive Objective C 'id' type. The user-visible 'id'
// type is a typedef of an ObjCObjectPointerType to an
// ObjCObjectType with this as its base. In fact, this only ever
// shows up in an AST as the base type of an ObjCObjectType.
BUILTIN_TYPE(ObjCId, ObjCBuiltinIdTy)
// The primitive Objective C 'Class' type. The user-visible
// 'Class' type is a typedef of an ObjCObjectPointerType to an
// ObjCObjectType with this as its base. In fact, this only ever
// shows up in an AST as the base type of an ObjCObjectType.
BUILTIN_TYPE(ObjCClass, ObjCBuiltinClassTy)
// The primitive Objective C 'SEL' type. The user-visible 'SEL'
// type is a typedef of a PointerType to this.
BUILTIN_TYPE(ObjCSel, ObjCBuiltinSelTy)
// This represents the type of an expression whose type is
// totally unknown, e.g. 'T::foo'. It is permitted for this to
// appear in situations where the structure of the type is
// theoretically deducible.
BUILTIN_TYPE(Dependent, DependentTy)
// The type of an unresolved overload set. A placeholder type.
// Expressions with this type have one of the following basic
// forms, with parentheses generally permitted:
// foo # possibly qualified, not if an implicit access
// foo # possibly qualified, not if an implicit access
// &foo # possibly qualified, not if an implicit access
// x->foo # only if might be a static member function
// &x->foo # only if might be a static member function
// &Class::foo # when a pointer-to-member; sub-expr also has this type
// OverloadExpr::find can be used to analyze the expression.
//
// Overload should be the first placeholder type, or else change
// BuiltinType::isNonOverloadPlaceholderType()
PLACEHOLDER_TYPE(Overload, OverloadTy)
// The type of a bound C++ non-static member function.
// A placeholder type. Expressions with this type have one of the
// following basic forms:
// foo # if an implicit access
// x->foo # if only contains non-static members
PLACEHOLDER_TYPE(BoundMember, BoundMemberTy)
// The type of an expression which refers to a pseudo-object,
// such as those introduced by Objective C's @property or
// VS.NET's __property declarations. A placeholder type. The
// pseudo-object is actually accessed by emitting a call to
// some sort of function or method; typically there is a pair
// of a setter and a getter, with the setter used if the
// pseudo-object reference is used syntactically as the
// left-hand-side of an assignment operator.
//
// A pseudo-object reference naming an Objective-C @property is
// always a dot access with a base of object-pointer type,
// e.g. 'x.foo'.
//
// In VS.NET, a __property declaration creates an implicit
// member with an associated name, which can then be named
// in any of the normal ways an ordinary member could be.
PLACEHOLDER_TYPE(PseudoObject, PseudoObjectTy)
// __builtin_any_type. A placeholder type. Useful for clients
// like debuggers that don't know what type to give something.
// Only a small number of operations are valid on expressions of
// unknown type, most notably explicit casts.
PLACEHOLDER_TYPE(UnknownAny, UnknownAnyTy)
// The type of a cast which, in ARC, would normally require a
// __bridge, but which might be okay depending on the immediate
// context.
