Is the 64-bit name of the general-purpose destination register, encoded in the "Xd" field. |

Is the 64-bit name of the first source general-purpose register or stack pointer, encoded in the "Xn" field. |
| <Xm> |
Is the 64-bit name of the second general-purpose source register, encoded in the "Xm" field. |
