A central concept 7265f016e2cb5d11daeb237544de1c5d59f20fe1a6eReid Spencer/// with types is that each type always has a canonical type. A canonical type 7275f016e2cb5d11daeb237544de1c5d59f20fe1a6eReid Spencer/// is the type with any typedef names stripped out of it or the types it 7285f016e2cb5d11daeb237544de1c5d59f20fe1a6eReid Spencer/// references. For example, consider: 7295f016e2cb5d11daeb237544de1c5d59f20fe1a6eReid Spencer/// 7305f016e2cb5d11daeb237544de1c5d59f20fe1a6eReid Spencer/// typedef int foo; 7315f016e2cb5d11daeb237544de1c5d59f20fe1a6eReid Spencer/// typedef foo* bar; 7325f016e2cb5d11daeb237544de1c5d59f20fe1a6eReid Spencer/// 'int *' 'foo *' 'bar' 7335f016e2cb5d11daeb237544de1c5d59f20fe1a6eReid Spencer/// 7345f016e2cb5d11daeb237544de1c5d59f20fe1a6eReid Spencer/// There will be a Type object created for 'int'. Since int is canonical, its 7355f016e2cb5d11daeb237544de1c5d59f20fe1a6eReid Spencer/// canonicaltype pointer points to itself. There is also a Type for 'foo' (a 73672564e73277e29f6db3305d1f27ba408abb7ed88Douglas Gregor/// TypedefType). Its CanonicalType pointer points to the 'int' Type. Next 7375f016e2cb5d11daeb237544de1c5d59f20fe1a6eReid Spencer/// there is a PointerType that represents 'int*', which, like 'int', is 7385f016e2cb5d11daeb237544de1c5d59f20fe1a6eReid Spencer/// canonical. Finally, there is a PointerType type for 'foo*' whose canonical 73972564e73277e29f6db3305d1f27ba408abb7ed88Douglas Gregor/// type is 'int*', and there is a TypedefType for 'bar', whose canonical type 7405f016e2cb5d11daeb237544de1c5d59f20fe1a6eReid Spencer/// is also 'int*'. 7415f016e2cb5d11daeb237544de1c5d59f20fe1a6eReid Spencer/// 7425f016e2cb5d11daeb237544de1c5d59f20fe1a6eReid Spencer/// Non-canonical types are useful for emitting diagnostics, without losing 7435f016e2cb5d11daeb237544de1c5d59f20fe1a6eReid Spencer/// information about typedefs being used.
