[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v6 09/42] x86emul: support AVX512{F, BW} integer unpack insns
There's once again one extra twobyte_table[] entry which gets its Disp8
shift value set right away without getting support implemented just yet,
again to avoid needlessly splitting groups of entries.
Signed-off-by: Jan Beulich <jbeulich@xxxxxxxx>
---
v6: Re-base over changes earlier in the series.
v4: Move OVR() additions into __AVX512VL__ conditional.
v3: New.
