Here is a reference to an article you may find interesting:


        `Interprocedural Optimization: Experimental Results', Richardson and
          Ganapathi, Software Practise & Experience, v19n2 (2/89).


I don't have the paper handy, but I believe they tested some algorithms in a
Pascal compiler on about 20 or 30 benchmarks. I think the authors were
disappointed with amount of improvement shown, and found the most difficult
algorithms the least effective!
