Summary
In this chapter, you learned how to convey the information about the assembly syntax and the encoding of the instructions of your target.
You saw how to augment the target description of your backend with this information and how to use the different TableGen backends to produce some of the tooling of the MC layer.
You saw how these tools provide you with a way to test the validity of your encodings early in the development of your backend. In other words, thanks to what you learned in this chapter, you do not need to build a full code generator pipeline to start checking that you are accurately modeling the ISA of your target architecture.
Speaking of the code generator pipeline, the next chapter will go over what needs to happen in this pipeline and the expected stages that the Machine IR will go through.
