* world_prop.v uses the ModuRes 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 triples
* iris_core.v defines erasure and the simpler assertions
* iris_wp.v defines weakest preconditions and proves the rules for
Hoare triples
* iris_vs.v defines view shifts and proves their rules
The development uses ModuRes, a Coq library by Sieczkowski et al. to
solve the recursive domain equation (see the paper for a reference)

REQUIREMENTS
Coq
8GB ram + 4GB swap
We have tested the development using Coq v. 8.4pl4 on Linux and Mac
machines with at least 8GB RAM + 4GB swap. The entire compilation
took around 3 hours.
machines with 8GB RAM. The entire compilation took around an hour.
HOW TO COMPILE
To compile the development, run
> make
> (cd lib/ModuRes; make) && make
in the folder containing this README.
Be aware that iris.v takes a long time to check and needs
significant amounts of RAM!
OVERVIEW OF LEMMAS
Below we give a mapping from proof rules in the paper to Coq lemma's
in Iris.v.
