Duet

Duet is a static analysis tool designed for analyzing concurrent programs.

Building

Dependencies

Duet depends on several software packages. The following dependencies need to be installed manually.

• opam (with OCaml 4.01 & native compiler)
• autotools
• GMP and MPFR

On Ubuntu, you can install these packages (except Java) with:

 sudo apt-get install opam autotools-dev libgmp-dev libmpfr-dev

Next, add the sv-opam OPAM repository, and install the rest of duet's dependencies. These are built from source, so grab a coffee — this may take a long time.

 opam remote add sv git://github.com/zkincaid/sv-opam.git
 opam install ocamlgraph batteries cil.1.7.3 oasis deriving Z3 apron.0.9.10 ounit

Building Duet

After Duet's dependencies are installed, it can be built as follows:

 autoconf
 ./configure
 make

Duet's makefile has the following targets:

• make: Build duet
• make ark: Build the ark library and test suite
• make apak: Build the apak library and test suite
• make doc: Build documentation
• make test: Run test suite

Running Duet

There are three main program analyses implemented in Duet:

• Data flow graphs (POPL'12): duet -coarsen FILE
• Heap data flow graphs: duet -hdfg FILE
• Compositional recurrence analysis: duet -cra FILE

Duet supports two file types (and guesses which to use by file extension): C programs (.c), Boolean programs (.bp).

By default, Duet checks user-defined assertions. Alternatively, it can also instrument assertions as follows:

duet -check-array-bounds -check-null-deref -coarsen FILE

Architecture

Duet is split into several packages:

• apak

  Algebraic program analysis kit. This is a collection of utilities for implementing program analyzers. It contains various graph algorithms (e.g., fixpoint computation, path expression algorithms) and utilities for constructing algebraic structures.

• ark

  Arithmetic reasoning kit. This is a high-level interface over Z3 and Apron. Most of the work of compositional recurrence analysis lives in ark.

• duet

  Implements program analyses, frontends, and anything programming-language specific.
