Self Hosted - A Self Hosted compiler project

Copyright (C) 2017 J. Férard https://github.com/jferard

This is an experimental project, and a work in progress.

Do not rely on it.

The project

I will try to make a tiny self hosted compiler, one part after another. The goal is to create in Python a compiler based on LLVM. This compiler should be able to compile itself.

The only requirements will be:

• LLVM
• a python 3 interpreteter
• python llvmlite module

Roadmap

There are two main steps : the bootstrap in Python, and the self hosted compiler.

The bootstrap

1. Create a tiny regex library in Python
2. Create a lexer on tiny regexes
3. Create a parser on BNF & lexer
4. Use the previous steps to output an executable build on LLVM

The self hosted compiler

1. Translate Python sources to self hosted syntax.
2. Tie this to LLVM
