That's part of it. The rest is:

n4:  dq 0xa77809bf11b239d1
n5:  dq 0x2ba9bf3d2f05b389
x6:  dq 0x1a1b2550a612b48c, 0x79445c159ce79064

     pxor   xmm0, xmm0
%assign i 6
%rep 16-6
     pxor   xmm %+ i, [x %+ i GLOBAL]
     por    xmm0, xmm %+ i
     %assign i i+1
     packsswb xmm0, xmm0
     movq   r5, xmm0
     or     r4, r5
