  • Customizable warnings with a GCC plugin GCC allows plugins and this give new opportunities. This allows to add rules which are specific to a project while the heart of GCC is made to be generic. The idea of this project is to write a plugin, which can be used to add more warnings when compiling, helping to improve the quality of the code. For this, I would like to use MELT, which is a plugin simplifying the writing of others plugins. This is still very simple checks but it can helps to respect commonly used rules.
  • Extend GFortran's Coarray support with MPI-based paralellization I will work with Tobias Burnus and other gfortran developers to advance support for Fortran 2008 coarrays to the point where real parallelization is possible. Specifically, I will use the Message Passing Interface (MPI) standard to build library-based support for coarray programs with multiple images.
  • GCC Optimisation This proposal involves improving performance of GCC, in both CPU and memory utilisation.
  • Gccpy - GCC Python Front-end Gccpy is a Python front-end to gcc from my last years GSOC (2010), I was mentored by Ian Lance Taylor who continues to be a great inspiration to me with his work on gccgo and his help on gcc-help to the community of users and developers.
