;; 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.
