llvm

LLVM IR is quite fun to play with from many programming languages. The Java example is rather educational, but there are several practical example,s such as in Go Lang: https://github.com/llir/llvm

I'm using this exactly. It's not the nicest interface but it supports almost everything that LLVM does. https://github.com/llir/llvm looks nice but I don't think you can interface with LLVM from there, which is needed if you want to do more advanced stuff.

Next step is to directly generate IR with (link: https://github.com/llir/llvm) github.com/llir/llvm. And then rewrite all of llvm in Go :)

@krasin The LLVM IR assembly language does change with a rather high rate. Not too often to be unfeasible, but an external project definitely needs to make sure it can keep up with maintenance to remain useful. Since the llir/llvm project started back in 2014, the LLVM IR assembly language has had one major change, and that is the new metadata syntax introduced in LLVM 3.6. To facilitate maintenance efforts over time, a BNF grammar for LLVM IR assembly has been written, from which the lexer and parser are generated [1,2,3]. The intention is for this BNF grammar to eventually become the basis or starting ground for an official BNF grammar of the LLVM IR assembly language (but that's a different project altogether, and a huge effort in itself).
