Moves are special as far as reload is concerned. If there is already a move instruction present *before* reload, it will get fixed up according to its constraints as any other instruction. However, reload will *introduce* new moves as part of its operation, and those will *not* themselves get reloaded. Instead, reload simply assumes that every plain move will just succeed without requiring any reload; if this is not true, the target *must* provide a secondary reload for this move. (Note that the secondary reload could also work by reloading the target address into a temporary; that's up to the target to implement.)
