------- Additional Comments From pinskia at gcc dot gnu dot org  2005-06-12 23:44 -------
Confirmed, on ppc-darwin we do reverse the loop and we use the do-loop patterns:
L4:
        lfsx f0,r2,r4
        add r2,r2,r7
        stfsx f0,r3,r0
        add r0,r0,r6
        bdnz L4
L11:
        lfsx f0,r2,r4
        add r2,r2,r7
        stfsx f0,r3,r0
        add r0,r0,r6
        bdnz L11

So we could improve for x86.
