Re:Ignition: V8 Interpreter

Common register allocation across different bytecode interpretation sequences was one of the things specifically on my mind that could be tuned using a high-level assembler.
Very suboptimal might be a slight overstatement. I can see a way, given known register calling conventions, that you could write an interpreter written as tail calls and post-process the machine code to effectively JMP instead of CALL. Guaranteed tail calls would save you a bunch of effort, and register calling convention would give you some guarantees about consistent allocation.
