PREREQUISITES


This version is known to compile with:

  Coq 8.5
  Ssreflect 1.6

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 folder `prelude` contains an extended "Standard Library" by Robbert
+ Krebbers .
+* 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
+ languageindependent derived constructions (e.g., STSs).
+* The folder `heap_lang` defines the MLlike concurrent heap language, and a
+ few derived constructions (e.g., parallel composition).
+* The folder `barrier` contains the implementation and proof of the barrier.
+* The folder `examples` contains the examples given in the paper.
