| ; The issue here is that FastISel cannot emit an ADDrr where one of the inputs |

| ; argument is at an offset > 2^12 * size from SP. |
| |
| ; If FastISel ever starts coping with this and emits an "add xD, sp, xM" it's |
| ; critical to check the encoding as well as the textual assembly. An ADDXrs with |
| ; SP as an operand will still print with SP, but will actually mean XZR. |
