Get a Local Copy of the GCC repository

- -

Using rsync to get a local copy of the GCC -repository is highly recommended for regression hunts. You'll -be checking out the tree used for the regression search over and over -again and won't want to affect access times for other GCC developers -who are using the real repository, and it will also be faster for -you.

The full tree takes a lot of disk space, but it's possible to -exclude directories you won't need for your hunt. If you're already -using a local SVN repository via rsync, -you can make a cut-down version of it that leaves out directories you -don't need for the regression hunt. This makes SVN operations much -quicker, making it worthwhile even if the copy is on the same system. -It's particularly useful if you'll want to copy it to a system that is -low on available disk space. The following, for example, makes a -smaller copy of the repository that can be used for finding C and C++ -compile-time problems and takes only half the disk space as the full -repository.
