while

This is an experiment with simple static analyses for a while language compiling to control flow graphs.

src/ConstraintSystem.hs

Contains a generic solver for constraints where the lattice is on sets.

src/CFG.hs

Contains the syntax definitions, and a very simple compiler from a while language to a CFG. The CFG has commands on edges.

src/Analysis.hs

Contains a few very simple analyses.

• Available expressions
• True liveness

src/Parser.hs

Simple parser for the while language.
