Based on previous, this becomes
cc = 3;
a0 = s390_vec_read_element64(v2, 0);
a1 = s390_vec_read_element64(v2, 1);
z0 = zero_search(a0, m);
if (z0) {
i = clz64(z0);
a0 &= ~(UINT64_MAX >> i);
a1 = 0;
cc = 0;
} else {
z1 = zero_search(a1, m);
if (z1) {
i = clz64(z1);
a1 &= ~(UINT64_MAX >> i);
cc = 0;
}
}
s390_vec_write_element64(v1, 0, a0);
s390_vec_write_element64(v1, 1, a1);
return cc;
