...so presumably it's the attr highlighted below:

 10920  (define_insn "*jcc_1"
 10921    [(set (pc)
 10922          (if_then_else (match_operator 1 "ix86_comparison_operator"
 10923                                        [(reg FLAGS_REG) (const_int 0)])
 10924                        (label_ref (match_operand 0))
 10925                        (pc)))]
 10926    ""
 10927    "%!%+j%C1\t%l0"
 10928    [(set_attr "type" "ibr")
 10929     (set_attr "modrm" "0")
>10930     (set (attr "length_nobnd")
>10931             (if_then_else (and (ge (minus (match_dup 0) (pc))

>10933                                (lt (minus (match_dup 0) (pc))
