--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Note in the testcase a = (struct buf) {}, b = (struct buf) {} generates
significantly more efficient code than a = b = (struct buf) {} - the former
is 2x memset, the latter 1x memset + 1x memcpy.
So, shall we for large aggregates gimplify those differently as an
optimization?
