Hi Martin,

Thanks a lot for your input.

Hi Kris,

just a short answer for now: At line 1229, I wonder why the immediate additions don't get normalized to e.g. using SubI exclusively (AddI doesn't cover const-var). This surely isn't something to be done now, just a general question of mine. You're right, (x - const) does get normalized to (x + -const), so we're good to just check AddI.

Maybe you could change in addition to (arraylength > 0) also (arraylength != 0) into (arraylength u> 0)?

I've added the pattern. Webrev updated in place again.

Thanks, Kris

Regards, Martin.
