The NuPlus.td file contains the definition of the Target class NuPlus (defined in "compiler/include/llvm/Target/Target.td"). The file also contains the definition of the NuPlusInstrInfo, NuPlusAsmParser and NuPlusAsmWriter required by the Target class. In addition, we avoid using instruction itineraries for scheduling. Itineraries are details reservation tables for each instruction class.
