For development, better make sure you have a version of Ssreflect that includes commit be724937 (no such version has been released so far, you will have to fetch the development branch yourself). Iris compiles fine even without this patch, but proof bullets will only be in 'strict' (enforcing) mode with the fixed version of Ssreflect.

Building Instructions

Run the following command to build the full development:

make

The development can then be installed as the Coq user contribution iris by running:

make install

Structure

The folder prelude contains an extended "Standard Library" by Robbert Krebbers http://robbertkrebbers.nl/thesis.html.
The folder algebra contains the COFE and CMRA constructions as well as the solver for recursive domain equations.
The folder program_logic builds the semantic domain of Iris, defines and verifies primitive view shifts and weakest preconditions, and builds some language-independent derived constructions (e.g., STSs).
The folder heap_lang defines the ML-like concurrent heap language
- The subfolder lib contains a few derived constructions within this language, e.g., parallel composition. Most notable here s lib/barrier, the implementation and proof of a barrier as described in http://doi.acm.org/10.1145/2818638.
The folder proofmode contains the Iris proof mode, which extends Coq with contexts for persistent and spatial Iris assertions. It also contains tactics for interactive proofs in Iris. Documentation can be found in ProofMode.md.
The folder tests contains modules we use to test our infrastructure. Users of the Iris Coq library should not depend on these modules; they may change or disappear without any notice.

Documentation

A LaTeX version of the core logic definitions and some derived forms is available in docs/iris.tex.
