Demanded Abstract Interpretation

Incremental and demand-driven abstract interpretation framework in OCaml

DAI requires:

• OCaml version 4.09.0+
• OPAM version 2.0.7+
• Dune version 2.5.1+
• System packages: libgmp-dev libmpfr-dev (for APRON numerical domains)
• Adapton version 0.1-dev (pinned as a local OPAM package via make install, per its README)
• tree-sitter OCaml bindings for Java, generated using semgrep/ocaml-tree-sitter-core and semgrep/ocaml-tree-sitter-languages. These are under active development so there has been some drift as this project is not currently actively maintained. We have pinned patched versions known to work with this project at the dai branch of forks at https://github.com/bennostein/ocaml-tree-sitter-core and https://github.com/bennostein/ocaml-tree-sitter-languages; check these out and follow their README instructions to generate the necessary package, then install with (cd ocaml-tree-sitter-languages/lang/java/ocaml-src && dune install --root .)

Build with make build and run synthetic-edit experiments (as in PLDI paper) with ./run_d1a_experiment
