[pinskia at gcc dot gnu dot org]

------- Comment #4 from pinskia at gcc dot gnu dot org  2007-12-19 01:28 -------
4.0.2 works:
        ld 9,[EMAIL PROTECTED](2)
        li 11,-29264
        stvx 2,9,11

In 32bit mode for 4.0.3:

        lis 9,[EMAIL PROTECTED]
        la 9,[EMAIL PROTECTED](9)
        li 11,-29264
        stvx 0,9,11

32bits, 4.1.0:
        lis 9,0x8
        ori 9,9,36272
        add 9,9,9
        stvx 2,0,9
