|---|---|---|---|---|
| RVR | V/V | AVX512F | Bitwise OR 16 bits masks k2 and k3 and place result in k1. |
| RVR | V/V | AVX512DQ | Bitwise OR 8 bits masks k2 and k3 and place result in k1. |
| RVR | V/V | AVX512BW | Bitwise OR 64 bits masks k2 and k3 and place result in k1. |
| RVR | V/V | AVX512BW | Bitwise OR 32 bits masks k2 and k3 and place result in k1. |

Description
Performs a bitwise OR between the vector mask k2 and the vector mask k3, and writes the result into vector mask k1 (three-operand form).
Operation
