Any idea about instructions marked as UNPREDICTABLE: can it then be UNDEFINED?
In other words: UNDEFINED REQUIRES the instruction to cause UND-exception, but
MAY UNPREDICTABLE do that, or does it have to execute normally except that the result may be whatever?
(I'm not yelling even if I used caps.)
I did as that same thing there Re: ARM/THUMB instructions that change execution path?
but I don't seem to get any answers. And this is probably more appropriate space anyway.
