Need help about LLVM build coroutine

[Richard (Rikki) Andrew Cattermole]

Even if I was to help you get that IR working, it won't do anything 
useful for you.

A coroutine in LLVM IR is the top of the call stack.

It must be able to see all functions it calls.

You can't pass a function in by pointer, it has to be hard coded.

This needs compiler support, you can't write code outside of the 
compiler for this.
