At Google we have a number of features developed internally that, for various reasons, have not yet been ported upstream.
We are currently looking for ways to (a) contribute these to mainline, and (b) avoid accumulating more local patches by trying to stay closer to upstream trunk for future contributions. To help stage these patches, I have created the SVN directory svn://gcc.gnu.org/svn/gcc/branches/google with two branches inside: google/integration A branch following trunk that contains some minimal patches that are likely not useful anywhere outside of Google's build environment. These are typically configuration patches. google/main A branch of google/integration that contains Google local patches that we are looking to contribute to trunk. Some of these patches are either in the process of being reviewed, or have not yet been proposed. The intent of this branch is to serve as a staging platform to allow collaboration with external developers. Patches in this branch are only expected to remain here until they are reviewed and accepted in trunk. Additionally, we expect to start creating google/gcc-X_Y to track upstream releases. These branches are going to track upstream releases plus patches from google/main. They will be used as a basis for the toolchains we build internally. Diego.
