Then if we have the ZT0 register, we reuse that index a second time when adding ZT0 don't we. I don't know if it has anything to do with the issue at hand, but it seems like `sme_regnum` needs to be incremented if `has_zt` and we're adding one more to the vector.


lol of course I misunderstood the loop.  After the last entry is added, the index and `sme_regnum` are incremented, then the comparison shows that we're beyond the number of sme registers, and it stops.  With `sme_regnum` already positioned after the last sme reg.
