5 ; The issue here is that FastISel cannot emit an ADDrr where one of the inputs
6 ; is SP. This only ever crops up with function calls, and then only if the
7 ; argument is at an offset > 2^12 * size from SP.
9 ; If FastISel ever starts coping with this and emits an "add xD, sp, xM" it's
10 ; critical to check the encoding as well as the textual assembly. An ADDXrs with
11 ; SP as an operand will still print with SP, but will actually mean XZR.
