--- Comment #9 from Richard Biener <rguenth at gcc dot gnu.org> ---
And the remaining issue with GCC 11 would be that we fail to account for the
GPR -> XMM move. Or the remaining issue for _all_ branches is that we fail
to realize that emulated "vector" CTORs are even more expensive since we lack
a good way to materialize the CTOR in a GPR (generic RTL expansion fails to
consider using shift + and for example).
Not sure what a good expansion of a V2SImode, V4HImode or V8QImode
CTOR to a GPR DImode reg would look like.
