# Check there are no COPY instructions surrounding ADDVI_W instruction.
# MIParser sets RegClassOrRegBank for parsed virtual registers.
# Constraining register classes when G_INTRINSIC intrinsic(@llvm.mips.addvi.w)
# gets selected into ADDVI_W works as expected.
# Check that setRegClassOrRegBank.ll has same output.
