[It really depends of what you want to do inside GCC, but....] Learn more about the pass machinery and the plugin machinery, and perhaps do some plugins yourself. IMHO (but I suppose many would disagree), developping a plugin (or a GCC MELT extension - see http://gcc-melt.org/ which also have some slides which could be useful to you) is best for code that you do not intend to push into the compiler (in other words, making a plugin has probably more sense than making your own private branch of GCC). Once you mastered what plugins can give you, you have understood some of the possibilities to develop GCC. Happy hacking. PS. And don't forget the legal aspects & prerequisites: http://gcc.gnu.org/contribute.html - they will take a long time, so start worrying about them right now! -- Basile STARYNKEVITCH http://starynkevitch.net/Basile/ email: basile<at>starynkevitch<dot>net mobile: +33 6 8501 2359 8, rue de la Faiencerie, 92340 Bourg La Reine, France *** opinions {are only mines, sont seulement les miennes} ***
