The GNU Compiler Collection includes front ends for C, C++, Objective-C, Fortran, Java, Ada, and Go, as well as libraries for these languages (libstdc++, libgcj,...). GCC was originally written as the compiler for the GNU operating system. The GNU system was developed to be 100% free software, free in the sense that it respects the user's freedom.

PARKAS contributes to the polyhedral compilation framework, also known as Graphite. We also distribute an experimental branch for a stream-programming extension of OpenMP, parallel data-flow programming, and automatic parallelization to a data-flow runtime or architecture. This experiment borrows key design elements to synchronous data-flow languages.

Tobias Grosser is the maintainer of the Graphite optimization pass of GCC.
