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
• bootstrap/ contains the bootstrapped CertiCoq plugin for Coq and a CertiCoq-compiled variant of MetaCoq's safe type checker.

Structure of the theories directory:

• theories/common: contains common code utilities
• theories/Compiler: contains the toplevel CertiCoq pipeline
• theories/LambdaBoxMut: mutual inductive version of MetaCoq's LambdaBox erased language
• theories/LambdaBoxLocal: variant where deBruijn indices are represented using N instead of nat. The transformation from LambdaBoxMut let-binds the definitions in the environment to produce a closed term.
• theories/LambdaANF contains the λANF pipeline (and conversions -- direct and LambdaANF -- to λANF)
• theories/Codegen contains the C code generator.
