--- Comment #6 from Christophe Leroy (christophe.leroy@c-s.fr) ---
Obviously, r9 is wrong

    2538:       13 04 c4 c4     vxor    v24,v4,v24
    253c:       7d 20 48 ce     lvx     v9,0,r9
    2540:       39 21 00 90     addi    r9,r1,144
    2544:       13 25 cc c4     vxor    v25,v5,v25
    2548:       7d 60 48 ce     lvx     v11,0,r9
    254c:       13 46 d4 c4     vxor    v26,v6,v26
    2550:       81 21 00 88     lwz     r9,136(r1)  <== r9 is loaded here
    2554:       13 67 dc c4     vxor    v27,v7,v27
    2558:       7d 11 a8 ce     lvx     v8,r17,r21
    255c:       11 5f 5b 06     vcmpgtsb v10,v31,v11
    2560:       11 6b 58 00     vaddubm v11,v11,v11
    2564:       81 41 00 8c     lwz     r10,140(r1)
==> 2568:       7c 00 48 ce     lvx     v0,0,r9
    256c:       39 21 00 a0     addi    r9,r1,160
    2570:       7d 80 48 ce     lvx     v12,0,r9
    2574:       39 21 00 b0     addi    r9,r1,176

So the stack must be clobbered somewhere
