--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Yeah,
(insn 12 11 13 (set (reg:DI 85)
        (lshiftrt:DI (subreg:DI (reg/v:OI 79 [ v32u128_1 ]) 0)
            (const_int 1 [0x1]))) pr69613-3.c:19 -1
     (nil))
and similar shifts by 1 look just weird when the TImode shift is with variable
shift count.
