   endfor
ADDVI.H:
   t = 011 || u54..0
   for i in 0 .. WRLEN/16-1
      WR[wd]16i+15..16i = WR[ws]16i+15..16i + t
   endfor
ADDVI.W:
   t = 027 || u54..0
   for i in 0 .. WRLEN/32-1
      WR[wd]32i+31..32i = WR[ws]32i+31..32i + t
   endfor
ADDVI.D:
   t = 059 || u54..0
   for i in 0 .. WRLEN/64-1
      WR[wd]64i+63..64i = WR[ws]64i+63..64i + t
