; The issue here is that FastISel cannot emit an ADDrr where one of the inputs
; is SP. This only ever crops up with function calls, and then only if the
; 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.
