> Why is computed_jump_p (insn) not returning true?
Actually it is the following insn:
(jump_insn 169 222 170 19 (set (pc)
(reg:DI 0 ax)) 515 {*indirect_jump_rtx64} (nil)
(insn_list:REG_LABEL 172 (nil)))
Which is a computed goto but at this point we have a REG_LABEL which causes computed_jump_p to
return false.
