Looks like some how this insn is being splitted up:
(insn 164 117 166 0x0 (parallel [
(set (reg:DF 127)
(unsigned_float:DF (reg/v:SI 122)))
(use (reg:SI 128))
(use (reg:DF 129))
(clobber (mem:DF (plus:SI (reg/f:SI 30 r30)
(reg:SI 141)) [0 S8 A8]))
(clobber (reg:DF 130))
]) -1 (nil)
(expr_list:REG_EQUAL (unsigned_float:DF (reg/v:SI 122))
(nil)))
