--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Most like the following pattern's predicates should be expanded to include
constants and not just registers.

(define_insn "*csinc2<mode>_insn"
  [(set (match_operand:GPI 0 "register_operand" "=r")
        (plus:GPI (match_operand 2 "aarch64_comparison_operation" "")
                  (match_operand:GPI 1 "register_operand" "r")))]


s/register_operand/general_operand/ here For the second predicate.

And maybe a few others.

It is similar what I just did for `*cmov<mode>_insn_insv` pattern.
