Chapter #4: Adding JIT and Optimizer Support - Because a lot of people are interested in using LLVM as a JIT, weвЂ™ll dive right into it and show you the 3 lines it takes to add JIT support.

Chapter #3: Code generation to LLVM IR - With the AST ready, we can show off how easy generation of LLVM IR really is.Nothing in Chapters 1 or 2 is LLVM-specific, the code doesnвЂ™t even link in LLVM at this point. This tutorial describes recursive descent parsing and operator precedence parsing. Chapter #2: Implementing a Parser and AST - With the lexer in place, we can talk about parsing techniques and basic AST construction.

LLVM obviously works just fine with such tools, feel free to use one if you prefer. In order to make this tutorial maximally understandable and hackable, we choose to implement everything in C# instead of using lexer and parser generators.

Chapter #1: Introduction to the Kaleidoscope language, and the definition of its Lexer - This shows where we are going and the basic functionality that we want it to do.

IвЂ™ve tried to put this tutorial together in a way that makes chapters easy to skip over if you are already familiar with or are uninterested in the various pieces. If you dig in and use the code as a basis for future projects, fixing these deficiencies shouldnвЂ™t be hard. In practice, this means that weвЂ™ll take a number of shortcuts to simplify the exposition.ДЇor example, the code uses global variables all over the place (but unlike the official C++ version, this C# version uses nice design patterns like visitors), etcвЂ¦

It is useful to point out ahead of time that this tutorial is really about teaching compiler techniques and LLVM specifically, not about teaching modern and sane software engineering principles. This will let us cover a fairly broad range of language design and LLVM-specific usage issues, showing and explaining the code for it all along the way, without overwhelming you with tons of details up front. The goal of this tutorial is to progressively unveil our language, describing how it is built up over time. The code in this tutorial can also be used as a playground to hack on other LLVM specific things. This tutorial will get you up and started as well as help to build a framework you can extend to other languages. This tutorial runs through the implementation of a simple language, showing how fun and easy it can be. Welcome to the вЂњ Implementing a language with LLVMвЂќ tutorial.
