It uses a Coq library in lib/ by Sieczkowski et al. to solve the recursive domain equation (see the paper for a reference).
This folder is organized as follows:
* core_lang.v contains the axioms about the language
* lang.v defines the threadpool reduction and derives some lemmas from core_lang.v
* masks.v introduces some lemmas about masks
* world_prop.v uses the aforementioned Coq library to construct the domain for Iris propositions
* iris.v is the main file and contains the actual logic and the proof of the rules for view shifts and Hoare tiples
Run "make" in this folder to build it all.
Be aware that iris.v takes a long time to check and needs significant amounts of RAM!
8GiB may be sufficient, but to be safe you should have 16GiB and give it around 2 to 3 hours.

CONTENTS
The folder is organized as follows:
* core_lang.v contains the axioms about the language
* lang.v defines the threadpool reduction and derives some lemmas from core_lang.v
* masks.v introduces some lemmas about masks
* world_prop.v uses the aforementioned Coq library to construct the domain for Iris propositions
* iris.v is the main file and contains the actual logic and the proof of the rules for view shifts and Hoare tiples
It uses a Coq library in lib/ by Sieczkowski et al. to solve the recursive domain equation (see the paper for a reference).
REQUIREMENTS
Coq
8GB ram
We have tested the development using Coq v. 8.4pl4 on a machine with 8GB RAM + 4GB swap.
HOW TO COMPILE
To compile the development, run
> make
in the folder containing this README.
Be aware that iris.v takes a long time to check and needs significant amounts of RAM!
8GiB may be sufficient, but to be safe you should have 16GiB and give it around 2 to 3 hours.
OVERVIEW OF LEMMAS
Below we give a mapping from proof rules in the paper to Coq lemma's in Iris.v
