   // There are a whole bunch of vmov variants, to transfer within
   // S/D/Q registers, between core integer registers and S/D,
   // and from small immediates into S/D.
   // For integer -> S/D/Q there is a variant which takes two integer
   // register to fill a D, or to fill two consecutive S registers.
   // Vmov can also be used to insert-element. E.g.,
   //    "vmov.8 d0[1], r0"
   // but insert-element is a "two-address" operation where only part of the
   // register is modified. This cannot model that.
   //
   // This represents the simple single source, single dest variants only.

Update this comment?

Done.
