--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
This looks like a severe bug in emit_reduc_half for V{64QI,32HI}mode where it
handles correctly the i 512, 256, 128, 64 steps, but not the i == 32 step
needed as last for V32HImode or both the i == 16 and i == 8 steps needed for
V64QImode.
