Whilest employeed at DEC-ERL one summer, Bill Bush & I beat (slightly) on this
compiler. I translated the internal tree representation into common lisp
lists, from which we were doing dataflow analysis for automatic

much cleaner than e.g., Berkeley 'pc' & you could even understand the
optimization strategies. Amazing. Various small benchmarks showed that the
compiler did perform very well on VAXen.
Sadly, it all came to naught as DEC blew ERL out of the water that summer. You
can get a Modula-3 to C translator from gatekeeper.dec.com. Don't know if
it's the same structure, though.
