--- Comment #3 from Roger Sayle <roger at nextmovesoftware dot com> ---
I suspect that the middle-end could be a bit more forgiving whilst expanding
vcond_mask.  If a target doesn't provide V1TImode, GCC can fall back to usi=
ng
V2DImode, and if that isn't supported V4SImode, then V8HImode then V16QImod=
e.
On x86-64, these all use the same vblendvb instruction or pand,pandn,por lo=
gic
(also known as V128BImode :-).=
