Purpose:

Immediate Bit Clear

Immediate selected bit position clear in each element.

Description: 

wd[i] = bit_clear(ws[i], m)

Clear (set to 0) one bit in each element of vector ws. The bit position is given by the immediate m modulo the size of the element in bits. The result is written to vector wd.

The operands and results are values in integer data format df.

Restrictions:

No data-dependent exceptions are possible.

Operation: 

BCLRI.B:
   t = m
   for i in 0 .. WRLEN/8-1
      WR[wd]8i+7..8i = WR[ws]8i+7..8i and (17-t || 0 || 1t)
   endfor
BCLRI.H:
   t = m
   for i in 0 .. WRLEN/16-1
      WR[wd]16i+15..16i = WR[ws]16i+15..16i and (115-t || 0 || 1t)
   endfor
BCLRI.W:
   t = m
   for i in 0 .. WRLEN/32-1
      WR[wd]32i+31..32i = WR[ws]32i+31..32i and (131-t || 0 || 1t)
   endfor
BCLRI.D:
   t = m
   for i in 0 .. WRLEN/64-1
      WR[wd]64i+63..64i = WR[ws]64i+63..64i and (163-t || 0 || 1t)
   endfor
