Many modern virtual machines, such as JVMs, .NET Framework and V8, employ a just-in-time (JIT) compiler to achieve their high-performance. There are two major compilation strategies; trace-based compilation and method-based compilation. They have their own advantages and disadvantages, so we presume that applying suitable strategies for different program parts is essential for faster execution. This paper proposes a new approach called the meta-hybrid JIT compiler framework, which combined the two strategies in a single meta-JIT compiler framework. We also present the proof-of-concept implementation BacCaml. We also report that some programs ran faster by the hybrid compilation in our experiments.
