add new optimization pass to the GCC optimizations

Hello, Can we add our own SSA optimizations passes to GCC? is there a plugin or API that can help doing this ? (since GCC is open source) to run this optimization, can we easialy add it to other optimizations performed by chosing one of the known GCC flag: O1, O2, ... Thanks Asma
