Vector Bit Move If Zero

Purpose:

Vector Bit Move If Zero

Vector mask-based copy bits on the condition mask being clear.

Description: 

wd = (ws AND NOT wt) OR (wd AND wt)

Copy to destination vector wd all bits from source v ector ws for which the corresponding bits from target vector wt are 0 and leaves unchanged all destination bits for which the corresponding target bits are 1.

The operands and results are bit vector values.

Restrictions:

No data-dependent exceptions are possible.

Operation: 

 WR[wd] = (WR[ws] and not WR[wt]) or (WR[wd] and WR[wt])

Exceptions:

Reserved Instruction Exception, MSA Disabled Exception.
