I thought that the existing coding for pdp11 makes LRA selectable (via = -mlra) and defaults to off. I had planned to change it to default to on = but leave it selectable. I suppose just having it on is ok too, = although the code from LRA wasn't as efficient as the old last I looked = (which is a while ago). paul
