; FIXME: we should disable sdwa peephole because dead-code elimination, that
; runs after peephole, ruins this test (different register numbers)

; Spill all SGPRs so multiple VGPRs are required for spilling all of them.

; Ideally we only need 2 VGPRs for all spilling. The VGPRs are
; allocated per-frame index, so it's possible to get up with more.
