Broadcast logical bitmask immediate to vector (unpredicated)
This instruction unconditionally broadcasts the logical bitmask immediate into each element of the destination vector. This instruction is unpredicated. The immediate is a 64-bit value consisting of a single run of ones or zeros repeating every 2, 4, 8, 16, 32 or 64 bits.
This instruction is used by the alias MOV.
