GCC has a policy of not backporting new features to release branches. This can be considered a new feature. In fact what might happen is disabling of the graphite support on the 4.7 branch instead. Is there a reason why you can't do development on the trunk? And then support a 4.7 for your own uses? At Cavium, we try to do development on an internal tree and then post them upstream. Though in the future we would like to do things upstream first and then backport features to a release branch that we handle internally. Thanks, Andrew Pinski
