------- Additional Comments From pinskia at gcc dot gnu dot org  2004-12-23 02:21 -------
Hmm, I get this for the loop on ppc:
L42:
        fmr f12,f0
L33:
        lfd f13,0(r11)
        add r11,r11,r7
        lfd f0,0(r9)
        addi r9,r9,8
        fmadd f0,f13,f0,f12
        bdnz L42

The problem the secondary bb is PR 19038 but other than that, this loop as optimizated as it gets on 
ppc.
