Keywords: source-to-source compiler, model-driven software engineering, retargetable compilation.

The Gecos (Generic Compiler Suite) project is a source-to-source compiler infrastructure developed in the Cairn group since 2004. It was designed to enable fast prototyping of program analysis and transformation and is aims the hardware synthesis and retargetable compilation domains.

Gecos is 100% Java based and takes advantage of modern model driven software engineering practices. It uses the Eclipse Modeling Framework (EMF) as an underlying infrastructure and takes benefits of its features to make it easily extensible. Gecos is open-source and is hosted on the Inria gforge at http://gecos.gforge.inria.fr .

The Gecos infrastructure is still under very active development, and serves as a backbone infrastructure to projects of the group (project S2S4HSL, ID.FIX). Part of the framework is jointly developed with Colorado State University and since 2012 it is used in the context of the ALMA European project.

Development in Gecos in 2012 have mostly focused on the polyhedral loop transformation engine and its use for hardware synthesis. As a part of the ALMA project, significant efforts are also being made to develop a coarse-grain parallelization engine targeting a distributed memory machine model.
