The risk (pun intended) we have going down this path is being orphaned, it has
happened in the past with other archs like the Nios. It took over 3 years and
the directly lobbing of Altera's management to get that changed. If the
maintainers here are active up streaming the changes then this is not an issue
the trees should be close, if the trees are not close and gcc is not updated
regularly we becomes wedged.
