  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 implemented the BacCaml framework for proof-of-concept.
We also report that some programs actually ran faster by the hybrid compilation
in our experiments.
