; Check there are no COPY instructions surrounding ADDVI_W instruction.
; All virtual registers were created with createGenericVirtualRegister
; which sets RegClassOrRegBank in VRegInfo.
; Constraining register classes when G_INTRINSIC intrinsic(@llvm.mips.addvi.w)
; gets selected into ADDVI_W works as expected.
; Check that setRegClassOrRegBank.mir has same output.
