With respect to SCC handling: In my experience the benefits of a truly minimal SSA form are very small and may not justify the extra complexity and calculations. At least back then we mostly added that version to the paper to present a complete solution, the default libfirm code didn't use it (but had a pass in the pipeline that would remove extra phis once).
