--- Comment #1 from Ramana Radhakrishnan <ramana at gcc dot gnu.org> ---
Hmmm, I'm not sure if such type punning pushes the attributes through. We seem
to think that the alignment will be 16 bits and not 8 bits at expand time.
(insn 6 3 7 2 (set (reg:SI 115)
(zero_extend:SI (mem:HI (reg/v/f:SI 112 [ p ]) [1 MEM[(const struct TU2
*)p_2(D)]+0 S2 A16]))) /tmp/al.c:17 -1
(nil))
