r/Compilers on Reddit: A simple LLVM backend tutorial

May 15, 2025 -

(repost without the actual free hosting link, reddit removes it)

Hi, I've written a guide/walkthrough for building a new LLVM backend inspired by the CraftingInterpreters book with inlined code blocks in diff style, so you can follow along. This just helps you get started and you'll have to explore the source code or other tutorials like the Cpu0 one for going further.

It is on GitHub https://github.com/optimisan/llvm-mips-backend and hosted at the link in the repo.

What I have written in somewhat depth is how patterns in TableGen work because I couldn't find a good resource on that. I'll be adding support for more instructions sometime later, but do contribute if you can, thanks! (I'm new to LLVM so it will be helpful if more experienced people can give any inputs)

Really enjoying the documentation! Thanks

Tutorial: Creating an LLVM Backend for the Cpu0 Architecture Release 12.0.19.10

With this code, readers can generate Cpu0 machine code through the Cpu0 LLVM backend compiler and observe how it · executes on a computer. However, execution is only possible for code that does not contain global variables or relocation · records requiring linker handling. The book is also available in PDF and EPUB formats online. This tutorial is aimed at LLVM backend developers but is not intended for experts.

Cpu0 Architecture and LLVM Structure — Tutorial: Creating an LLVM Backend for the Cpu0 Architecture

To create a new backend, several files in <<llvm root dir>> must be modified. The required modifications include adding both the machine ID and name, as well as defining relocation records. The ELF Support chapter provides an introduction to relocation records.

September 13, 2020 - In this tutorial, I will develop a backend for the basic 32-bit version of the RISC V instruction set, ie. RV32IM. Hopefully this helps anyone who is unfamiliar with LLVM to get started with the tool and extend it for their own projects.

Backend structure — Tutorial: Creating an LLVM Backend for the Cpu0 Architecture

Most of them are common across different backends, except for the backend name (e.g., Cpu0 or Mips). In fact, we copy almost all the code from Mips and replace the name with Cpu0. Beyond understanding DAG pattern matching in theoretical compilers and the LLVM code generation phase, please focus on the relationships between classes in this backend structure.
