Threaded Code Generation with a Meta-Tracing JIT Compiler.

Language implementation frameworks, e.g., RPython and Truffle/Graal, are practical tools for creating efficient virtual machines, including a well-functioning just-in-time (JIT) compiler. It is demanding to support multitier JIT compilation in such framework language developers. This paper presents an idea generate threaded code by reusing existing meta-tracing compiler, as well interpreter design it. Our approach does not largely modify itself but constructs effective definition enable generation RPython. We expect our system be extended multilevel the framework. measured potential performance of simulating its behavior PyPy. confirmed that reduced sizes 80 \% times 60 compared PyPy's compiler on average, ran about 7 faster than interpreter-only execution.
