at 4, so calculating the value of fpsize
should be straightforward.
It feels like this could be improved. Do you agree?

Hello,
I just noticed when moving port from 4.7.2 to HEAD that genattrtab gets into an
infinite loop with:
(define_insn "br_pred"
[(set (pc)
(if_then_else
(match_operator 2 "easy_comparison"
[(match_operand:BI 0 "register_operand" "c")
(const_int 0)])
