Thanks so much for your patch. It

Hi,
This patch enables vector compare for 16-byte memory equality compare.
The 16-byte memory equality compare can be efficiently implemented by
instruction "vcmpequb." It reduces one branch and one compare compared
with two 8-byte compare sequence.
16-byte vector compare is not enabled on
