I was looking at the spec 456.hmmer benchmark and this email string
from Jeff Law and Micheal Matz:
https://gcc.gnu.org/ml/gcc-patches/2015-11/msg01970.html
and was wondering if anyone was looking at what more it would take
for GCC to vectorize the loop in P7Viterbi. There is a big performance
win to be had here if it can be done but the alias checking needed
seems rather extensive.
