Like I said, I'm not an expert.
I thought we were planning to make trees language-independent. In
which case clearly optimisations thereon would have to be language
independent. I don't really know what kind of optimisations you're
referring to, but we should aim to have enough information in the tree
format that the front ends can supply all the optimisation information
the lang-indep optimisers need (or, optimise whilst creating the
trees).
