------- Additional Comments From pinskia at gcc dot gnu dot org  2004-08-02 01:02 -------
Confirmed, I think this is a target problem:
(insn:TI 36 20 37 0 (set (reg:SI 0 0 [134])
        (gt:SI (reg:CCFP 75 7 [135])
            (const_int 0 [0x0]))) 422 {*rs6000.md:11384} (insn_list 34 (nil))
    (expr_list:REG_DEAD (reg:CCFP 75 7 [135])
        (nil)))

(insn:TI 37 36 23 0 (set (reg:DI 0 0 [131])
        (zero_extend:DI (reg:SI 0 0 [134]))) 12 {*rs6000.md:374} (insn_list 36 (nil))
    (expr_list:REG_EQUIV (mem/i:DI (reg/f:DI 10 10 [128]) [4 l2+0 S8 A64])
        (nil)))

(insn:TI 23 37 38 0 (set (reg:DI 9 9 [122])
        (eq:DI (reg:CCFP 74 6 [126])
            (const_int 0 [0x0]))) 423 {*rs6000.md:11416} (insn_list:REG_DEP_ANTI 32 
(insn_list:REG_DEP_OUTPUT 29 (insn_list 20 
(nil))))
    (expr_list:REG_DEAD (reg:CCFP 74 6 [126])
        (expr_list:REG_EQUIV (mem/i:DI (reg/f:DI 11 11 [119]) [4 l1+0 S8 A64])
            (nil))))

But I could be wrong.
