CertiCoq

Overview

CertiCoq is a compiler for Gallina, the specification language of the Coq proof assistant. CertiCoq targets Clight, a subset of the C language that can be compiled with any C compiler, including the CompCert verified compiler.

Large parts of the CertiCoq compiler have been verified whereas others are in the process of being verified.

Documentation

The CertiCoq Wiki has instructions for using the CertiCoq plugin to compile Gallina to C and interfacing with the generated C code.

You can also find some demos here and here.

Directory structure

• theories/ contains the sources of the compiler
• plugin/ contains the CertiCoq plugin for Coq
• benchmarks/ contains the benchmark suite
• glue/ contains the glue code generator

Structure of the theories directory:

• theories/common: contains common code utilities
• theories/Compiler: contains the toplevel CertiCoq pipeline
• theories/L1g: 1st pass, moves from (MetaCoq's) λbox to our similar L1g
• theories/L2k_noCnstrParams: 2nd pass, eta expands constructors and removes constructor parameters
• theories/L4_deBruijn: 3rd pass, let-bind environment
• theories/L6_PCPS contains the λANF pipeline (and conversions -- direct and CPS -- to λANF)
• theories/L7 contains the C code generator.
• theories/compcert contains a local copy of the compcert compiler
