Well, I can provide a complete garbage collected VM. :-)

The hard part of writing an LLVM backend for ocamlopt is probably getting LLVM
to generate code that is compatible with OCaml's GC, particularly the stack.
However, I believe Gordon Henriksen already did this:
"Included in the pending LLVM garbage collection code generation
changeset is an Ocaml frametable emitter." -

Unfortunately, I will not have any spare time until my next book is out...
Did any of the OCaml+LLVM student projects get funded in the end?
