THIS PROJECT IS UNSTABLE AND DEPRECATED
I have since started slow work on a more stable, better thought-out project called RabbitVM. It doesn't quite have the same level of documentation but it should work much better.
This is a project I've been slowly working on for about half a year now. The goal is to try and build a small (and decently reliable) VM from the ground up, learning more and more C as I go.
Right now there are instructions, registers, a stack, data memory, and calls. Not sure if recursion works... it should in theory. Haven't tested.
CONSIDER THIS PRE-ALPHA SOFTWARE. Things change more than they do in Rust!
If you already have a local copy (cloned before submodule was added)
git submodule init
git submodule update
If you don't already have a local copy
git clone --recursive
git submodule status doesn't return a SHA1 hash and repository name, you have a problem.
NOTE: Recursive clone is for testing library. If not included, tests will not build.
