The long-awaited reposurgeon tool is still not ready and although Maxim Kuvyrkov has developed an alternative set of scripts to go further with the project of converting GCC's code base from SVN to Git.

A few weeks ago it was decided to put a stop to the discussions and pick one of the working solutions (apparently both versions indeed work, but often not as intended due to the SVN design differing from Git).
