Operation: 

ADDV.B:
   for i in 0 .. WRLEN/8-1
      WR[wd]8i+7..8i = WR[ws]8i+7..8i + WR[wt]8i+7..8i
   endfor
ADDV.H:
   for i in 0 .. WRLEN/16-1
      WR[wd]16i+15..16i = WR[ws]16i+15..16i + WR[wt]16i+15..16i
   endfor
ADDV.W:
   for i in 0 .. WRLEN/32-1
      WR[wd]32i+31..32i = WR[ws]32i+31..32i + WR[wt]32i+31..32i
   endfor
ADDV.D:
   for i in 0 .. WRLEN/64-1
      WR[wd]64i+63..64i = WR[ws]64i+63..64i + WR[wt]64i+63..64i
   endfor
