--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
What is wrong rather not understanding the incoming arguments is passed as =
q0
rather than d0/d1.

(insn 2 6 3 2 (set (reg/v:V2x8QI 101 [ cols_01_23 ])
        (reg:V2x8QI 32 v0 [ cols_01_23 ])) "t66.c":5:1 -1
     (nil))
(insn 3 2 4 2 (set (reg/v:V2x8QI 102 [ cols_45_67 ])
        (reg:V2x8QI 33 v1 [ cols_45_67 ])) "t66.c":5:1 -1
     (nil))
