Hi, I looked over the gllvm sources, looks interesting. There is no equivalent for gollvm, someone would need to contribute it. I don't see any fundamental reason why it would not work, but I am sure there would be challenges and wrinkles.
One thing to note is that gllvm is emitteding bitcode (*.bc) files, not LLVM IR dumps (*.ll).
