[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v6 14/42] x86emul: basic AVX512DQ testing
Test various of the insns which have been implemented already.
Signed-off-by: Jan Beulich <jbeulich@xxxxxxxx>
---
v6: Re-base.
v5: Re-base over changes earlier in the series.
v4: Wrap OVR(pmullq) in __AVX512VL__ conditional.
v3: New.
