I guess I'll have to look harder to see if it's possible to make LRA handle CISC addressing modes like memory indirect, autoincrement, autodecrement, and others that the old reload handles at least somewhat. Ideally LRA should do a better job; right now I believe it doesn't really do these things at all. Targets like pdp11 and vax would like these.
