To register the code emitter, the following code needs adding to the machine code target description archMCTargetDesc.cpp.

  // Register the MC code emitter
  TargetRegistry::RegisterMCCodeEmitter(ThearchTarget,
                                        llvm::createarchMCCodeEmitter);

        

The createarchMCCodeEmitter function is declared in the archMCTargetDesc.h header file and is defined in archMCCodeEmitter.cpp. This function simply creates and returns a new archMCCodeEmitter.
