Which one exactly are you referring to?
I think we could improve a few things (in particular operations on string/set constants) by not converting things to backend trees so early. AFAIK, we'll have to do something like what Gnat does sometime anyway to support TreeSSA in a future GCC version, but I hope we can do it in a rather lightweight way. I think, using extended trees (only where necessary/useful) in the frontend and translate them to backend trees at the latest moment should be possible. The latter will require recursive traversal of expression trees, but this isn't such a big deal, we do it for schemata already.
