CoqJVM

This repository contains:

  • An executable semantics for a substantial fragment of the JVM in Coq [1];
  • a verifier for simple resource properties where the specifications and proofs are embedded in class files, written in Coq;
  • an OCaml library for dealing with JVM classfiles; and
  • a slightly modified copy of extlib 1.5 (see below).

At the time of writing, I was able to build it with OCaml 4.02.3 and Coq 8.5rc1. To build it you must first install ocamldsort, then run make in the extlib-1.5 directory, followed by the ocaml-jvml-bob directory. The main development can then be built by make all.

The copy of extlib-1.5 has been modified. In particular (from the original svn logs):

  • Properly implement the header=false option in extlib's unzip
  • Fix off-by-one error in extlib's unzip module

and there are some minor changes to the IO module. Some of the unzip changes may be in later versions of extlib.
