fwiw, "insn" seems to be:

(jump_insn:TI 10 4 56 2 (set (pc)
        (if_then_else (eq (reg:CCGC 17 flags)
                (const_int 0 [0]))
            (label_ref 29)
            (pc)))
/home/david/coding-3/gcc-git-jit-valgrind/get-attr-length-i386.c:3 610 {*jcc_1}
     (int_list:REG_BR_PROB 2000 (nil))
 -> 29)
