Indeed. 68K is a perfect candidate for addressing mode optimization (AMS). It was actually one of the next targets on the list after SH. What's with all that hurry to kill the old reload? Unless LRA can be brought "up to speed" for all other targets and vice versa, ripping out old reload and all the dependent targets would be a set back for GCC, IMHO. It would lose a bunch of targets.
