Moving to git

[Jason Merrill]

I hear that at Cauldron people were generally supportive of switching 
over to git as the primary GCC repository, and talked about me being 
involved in that transition.  Does anyone have more information about 
this discussion?

Our current workflow translates over to a git master pretty easily: 
basically, in the current git-svn workflow, replace git svn rebase and 
git svn dcommit with git pull --rebase and git push.

It should be pretty straightforward to use the existing git mirror as 
the master repository; the main adjustment I'd want to make is rewriting 
the various subdirectory branches to be properly represented in git. 
This is straightforward, but we'll want to stop SVN commits to 
subdirectory branches shortly before the changeover.

It would be good to have a more explicit policy on branch/tag creation, 
rebasing, and deletion in the git world where branches are lighter 
weight and so more transient.
