Abstract

This article presents the code generation scheme of the OCaml-Java compiler. The goal of the OCaml-Java project is to allow execution of OCaml programs on a Java Virtual Machine. In order to achieve decent performance, it is necessary to build a compiler producing optimized bytecode that will rely on an efficient support library at runtime.

The OCaml-Java project thus provides \((i)\) an efficient runtime written in pure Java, and \((ii)\) an optimizing compiler based on the original OCaml compilers for the front-end and on the Barista library for the back-end.

Notes

  1. 1.

    Already present in previous version, but not production-ready.

  2. 2.

    Despite their name, some constants may in fact be modified, hence the impossibility to share them between programs running in the very same Java Virtual Machine.

  3. 3.

    The Hotspot compiler can remove such tests if it can prove that no illegal access will happen, but the developer can not request to remove such tests.

  4. 4.
