Description
Converts a mask register to a vector register. Each element in the destination register is set to all 1’s or all 0’s depending on the value of the corresponding bit in the source mask register.
The source operand is a mask register. The destination operand is a ZMM/YMM/XMM register.
EVEX.vvvv is reserved and must be 1111b otherwise instructions will #UD.
