The use is deleted because insn 434 has been retargeted from
code_label 322 to code_label 465:
(insn 434 58 366 ../../gcc/gcc/basic-block.h:194 (sequence [
(jump_insn 59 58 92 ../../gcc/gcc/basic-block.h:194 (set (pc)
(if_then_else (gtu (reg:SI 28 %r28 [orig:132
<variable>.base.num ] [132])
(const_int 2 [0x2]))
(label_ref:SI 465)
(pc))) 25 {*pa.md:1770} (expr_list:REG_DEAD (reg:SI 28
%r28 [orig:132 <variable>.base.num ] [132])
(expr_list:REG_BR_PROB (const_int 9700 [0x25e4])
(nil))))
(insn/s 92 59 366 (set (reg/v:SI 4 %r4 [orig:111 i ] [111])
(const_int 2 [0x2])) 37 {*pa.md:2542} (expr_list:REG_EQUAL
(const_int 2 [0x2])
(nil)))
]) -1 (nil))
The code_label 322 then has zero uses.
