The problem is that genrecog tests sets operand for non-VIUDmode.
But the operand is (match_dup num), that seems to be VOIDmode to genrecog
but of course isn't in reality.
So the warning is bogus and it is in my TODO list to fix these.
I will try to give it higher proirity , since this issue remains
in tree for a while. I am really busy lately :(
