Please explicitly say that this is the current *SVE* vector length, given that with SME entering streaming mode means we have SVE registers with the current streaming vector length which may be different to the SVE vector length it is possible that someone may read the above as referring to the vector length that applies to the current Z/P registers. --mk/wbO/L6mmEEdnA Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmJ5NycACgkQJNaLcl1U h9Dbdwf+PcSNippPQhwEFZ7lU/qxZTpSVBuoGp0Z1YUpzKhv2UgfZEbPz6WHtW89 W2jmtd52nfsNTc6old7JvHErzT3sdhrD5cdlNmZ8e5La/GS1NOwcLZKinXEarsqY 3nJPHYmKvSXCZCFuSMmnHB1xpTCZFou8dxgruNczu1DONbfXU0uil0bXHchEOYxa Z3Bk5WdShpD67OwH9hgX4ub2ML5XEXpSmQnhKBZSGs4UIOETKvmraf7TYYZBWkZy 2RW6BJ4yE8/ZzWVx/HLPKzIlO9XPZN5Hl5gVsTQsk1uRK1fAPQNydQfITl3PPX7R kmOKG0EK5Ov5rfaVdR8OQqXvIw/iMw== =saF4 -----END PGP SIGNATURE----- --mk/wbO/L6mmEEdnA--
