The results presented in this paper were generated by the
experimental compiler developed at Edinburgh University.
We used all thirteen Perfect Club programs as test
programs, and compiled each of them under a variety of optimizations.
Execution frequencies for each basic block were obtained by
profiling the programs on a Sun SPARC workstation using the
-a compiler option. This produces a profile file
which is automatically sensed and imported by the experimental
compiler. The compiler is therefore able to report the
exact execution frequency of each LOD, and also to report
the type of LOD. Frequency information can be observed in
any of the LOD display windows included with this document.
