--- Comment #12 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Kirill, any progress on:
"And, for AVX512-{F,BW,VL}, I'm surprised that the broadcasts from gprs are
done as different instructions from broadcasts from memory or vector reg, I
would have thought that must have been done using a single insn with
alternatives."
