--- Comment #6 from Peter Bergner <bergner at gcc dot gnu.org> ---
This whole lra reload is due to us trying to split insns like the following:

(insn 129 281 264 9 (set (subreg:TF (reg:TI 315 [orig:262 p1 ] [262]) 0)
        (reg/v:TF 173 [ p1 ])) "pr78458.i":17 1930 {*frob_ti_tf_2}
     (expr_list:REG_DEAD (reg/v:TF 173 [ p1 ])
        (nil)))

Old reload just leaves the insn alone.
