Thanks for being patient with my mistakes.  Between the two of us, we'll catch
each other's mistakes and both end up stronger for it.

OK I think I found a bug on an old fix to redeem myself....

0x000000bf returns strheq r0, [r0], -pc (pc = r15)

ARM ARM say for this situation neither Rn nor Rm can be pc (R15).
Hence, we need an "; <UNPREDICTABLE>" for this case too.

P.S. By the way, I'm using ARM ARM version ARM DDI 0100I which has different
page numbers than your version.  I can send you my PDF if you wish.
