Yhi is all written in C, and you are unlikely to need to delve into
the Haskell side of things. src/runtime/BCKernel should be where you
spend most of your time.

Not really, GHC does, but its hardly abstract C. I'd definitely follow
the bytecode route, or you're going to be doing a lot more work.

Thanks
