Wonderful, we are delighted you found contributing to GCC interesting and happy to hear that you have got past the first steps. > > On the other hand, I have been studying GCC’s codes, optimization > flags to be more specific.

Unfortunately, this project idea apparently has not quite caught much attention. I myself struggle with understanding what is supposed to be dependent on what and don't think that simply mapping dependencies from optimization levels to individual warning options is a project that should span three months. You'd need to substantially extend the scope somehow or perhaps look for another idea, our wiki still has a few that nobody took up. If I misunderstood something, please feel free to correct me and/or ask anything specific that you'd like to know about GCC. Thanks, Martin
