[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v3 18/34] x86emul: support AVX512{F, BW} packed integer arithmetic insns
Note: vpadd* / vpsub* et al are put at seemingly the wrong slot of the
big switch(). This is in anticipation of adding vpunpck* to those
groups (see the legacy/VEX encoded case labels nearby to support this).
