Summary
In this chapter, you learned basic jargon and concepts that you will manipulate in your day-to-day job as a compiler engineer. Things such as module, function, basic block, instruction, CFG, have no secret for you now.
You also learned how these concepts map to LLVM APIs, both at the LLVM IR and the Machine IR levels. While you only scratched the surface of these APIs, you now have a mental model of what offers what and have a few concrete pointers to start digging more into them.
Your next stop is with more advanced compiler concepts that will allow you to go deeper into the LLVM infrastructure and give you an idea of what it takes to write your first optimization. Before you go there, you have guessed it – it is quiz time!
