Great. That doesn't make too much sense ;) Because the testcase in comment #7
cannot be "optimized" on the tree level, but I see it is wrongly expanded to
RTL instead.
Now, the revisions are
103956: make tree-PRE smarter, looking through loads
119760: mem-ssa merge (my favorite)
126149: SCCVN merge
nothing expansion related or FE specific. Bah.
