I don't know, but there has been talk about re-doing the C/C++
front-end so that entire function bodies are represented using
tree nodes, rather than just generating tree nodes for each
statement, generating rtl for a single statement, and then
throwing away the tree node.
Representing an entire function body as a tree node should
allows us to do more high-level optimizations.
