Before peephole2:

(insn:HI 27 60 28 2 (set (reg:DF 0 0 [125])
        (mem/u/c/i:DF (reg/f:SI 9 9 [126]) [3 S8 A64])) 892
{*movdf_e500_double} (insn_list:REG_DEP_TRUE 26 (nil))
    (expr_list:REG_DEAD (reg/f:SI 9 9 [126])
        (expr_list:REG_EQUIV (const_double:DF 1.0e+0 [0x0.8p+1])
            (nil))))

(insn:HI 28 27 32 2 (set (subreg:DF (reg:DI 3 3 [128]) 0)
        (reg:DF 0 0 [125])) 889 {*frob_di_df_2} (insn_list:REG_DEP_TRUE 27
(nil))
    (expr_list:REG_DEAD (reg:DF 0 0 [125])
        (nil)))

After peephole2:
(insn 77 60 32 2 (set (subreg:DF (reg:DI 3 3 [128]) 0)
        (mem/u/c/i:DF (reg/f:SI 9 9 [126]) [3 S8 A64])) -1 (nil)
    (expr_list:REG_DEAD (reg/f:SI 9 9 [126])
        (nil)))
