19// There are basically four ways that we end up doing message dispatch for the
20// NeXT runtime. They are:
21//  (1) fragile ABI, legacy dispatch
22//  (2) non-fragile ABI, legacy dispatch
23//  (2) non-fragile ABI, non-legacy dispatch
24//  (2) non-fragile ABI, mixed dispatch
25//
26// Note that fragile ABI and non-fragile ABI legacy dispatch are not the same,
27// they use some different API calls (objc_msgSendSuper vs objc_msgSendSuper2).
