------- Additional Comments From pinskia at gcc dot gnu dot org  2005-06-13 12:46 -------
On the mainline we get now:
.L4:
        movl    (%ebp,%edx,4), %eax
        movl    %eax, (%ebx,%edx,4)
        movl    (%esi,%edx,4), %eax
        movl    %eax, (%ecx,%edx,4)
        incl    %edx
        cmpl    %edx, %edi
        jne     .L4

Which is better but the two loads/stores are not scheduled.
