; FIXME: The MUBUF loads in this test output are incorrect, their SOffset
|
|
; should use the frame offset register, not the ABI stack pointer register. We
|
|
; rely on the frame index argument of MUBUF stack accesses to survive until PEI
|
|
; so we can fix up the SOffset to use the correct frame register in
|
|
; eliminateFrameIndex. Some things like LocalStackSlotAllocation can lift the
|
|
; frame index up into something (e.g. `v_add_nc_u32`) that we cannot fold back
|
|
; into the MUBUF instruction, and so we end up emitting an incorrect offset.
|
|
; Fixing this may involve adding stack access pseudos so that we don't have to
|
|
; speculatively refer to the ABI stack pointer register at all.
|
|
|
|
; An assert was hit when frame offset register was used to address FrameIndex.
