I suspect that this patch could take wo= rk away from other patches. I'm sorry, I don't know how to express myself properly. I mean there's several patches that corrects shift patterns and '= tst' instruction generation (most of them are written by you, by the way). I sus= pect that some of them might not run anymore because this patch looks more gener= al and should cover more cases, including yet unknown cases, I hope. And, in t= he end, dead code may appear because of it. I hope I was able to make my point clearly.=
