Hi Mark,

I propose the application of the attached patch that rewrites
such bogus CBZ instructions to no-ops.  This isn't particularly
elegant, but does make this robust.  OK?

The patch is OK, but ... is it necessary to actually generate any instructions at all ? Wouldn't it be more elegant to just omit generating an instruction, saving a couple of bytes ?

Cheers
  Nick
