This directory contains source for various performance benchmarks
. Some simple tests of function calls and dispatching are given for Sather, Eiffel and C++ in "ahmad_bench.sa", "ahmad_bench_eiffel.e", and "ahmad_bench_c++.cc". The Eiffel results are in "eiffel_results.txt". The Sather and C++ results are in "results". The rest of the files are a series of tests that were derived from the Stanford Integer Benchmarks gathered by Hennessy. The "*.sa" files give Sather versions and the "*.cc" give C++ versions. A comparison of the results is given in "results".
