;; Insn is not within a basic block
(code_label 48 47 49 11 "" [3 uses])

;; Insn is not within a basic block
(jump_insn 49 48 50 (addr_diff_vec:DI (label_ref:DI 48)
         [
            (label_ref:DI 103)
            (label_ref:DI 103)
            (label_ref:DI 103)
            (label_ref:DI 103)
            (label_ref:DI 103)
        ]
        (const_int 0 [0x0])
        (const_int 0 [0x0])) -1 (nil)
    (nil))


So we lose a jump table.
