--- Comment #7 from Kirill Yukhin <kyukhin at gcc dot gnu.org> ---
On the other hand, if masked variant of vpopcnt[w,q] is being issued: there's
no way for reload to put 32/64 bit mask into mask register, since kmov[d,q] are
only available under -mavx512bw switch.
We can insist user to issue -mavx512bw along w/ -mavx512bitalg if she is going
to use masked variants of corresponding intrinsics. Then only tests need to be
fixed.
