--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Doesn't seem to. The cfg layout cleanup code simply tries to redirect a
CROSSING_JUMP_P, which apparently on aarch64 looks like:
(insn 119 80 120 5 (set (reg:DI 110)
(high:DI (label_ref:DI 19))) -1
(insn_list:REG_LABEL_OPERAND 19 (nil)))
(insn 120 119 121 5 (set (reg:DI 109)
(lo_sum:DI (reg:DI 110)
(label_ref:DI 19))) -1
(insn_list:REG_LABEL_OPERAND 19 (expr_list:REG_EQUAL (label_ref:DI 19)
(nil))))
(jump_insn/j 121 120 19 5 (set (pc)
(reg:DI 109)) -1
(nil)
-> 19)
and fails to adjust that, because the insn doesn't have the label directly in
the insn, it is like a computed jump, but not recognized as such because it has
non-NULL JUMP_LABEL.
