--- Comment #11 from Jiu Fu Guo <guojiufu at gcc dot gnu.org> ---
While for the const which Bill said in comment9, 0x000800004100001
The code sequence still contains a few instructions:
e.g.
        li %r11,0
        ori %r11,%r11,0x8000
        sldi %r11,%r11,32
        oris %r11,%r11,0x410
        ori %r11,%r11,0x1
        std %r11,0(%r3)
