--- Comment #12 from Andrew Pinski <pinskia at gcc dot gnu.org> --- This definitely helped highway. I still see some extra BIT_FIELD_REF but I am not 100% sure as I forgot to turn on uid on the dump so I don't know which variable is being assigned to which one. If I can get another testcase I will file it seperately.
