; Due to high register pressure, regalloc would split the liverange of wwm VGPR register used for SGPR spills
; and introduce a copy. The copy should be of whole-wave with exec mask manipulation around it.
; FIXME: The destination register involved in the whole-wave copy should be considered for preserving all the lanes
; with a spill/restore at function prolog/epilog. The copy might otherwise clobber its inactive lanes unwantedly.
