Your testcase works for me on i686-pc-linux-gnu with 'GCC: (GNU) 4.4.0 20080605
(experimental) [trunk revision 136389]', with -mmmx and all optimization
levels:

.L5:
        movq    %mm1, %mm0
        psllq   $8, %mm0
        psllq   $8, %mm0
        movq    %mm0, (%ecx,%eax,8)
        addl    $1, %eax
        movq    %mm0, %mm1
        cmpl    %eax, %edx
        jg      .L5
