  11. NOTE: We did not run benchmarks on 2.17 yet; test results are
  12.       given for 2.12.

  14. The directory samples\simple contains the following benchmark
  15. programs:
  16.  
  17.         dry.mod         Drystone  (Modula-2)
  18.         dry.c           Drystone  (C)
  19.         whet.mod        Whetstone (Modula-2)
  20.         linnew.mod      LinPack   (Modula-2)
  21.         linnew.c        LinPack   (C)
  22.  
  23. These tests can be used to compare different platforms and different
  24. compilers.  We include C sources to make it possible to compare the
  25. quality of the generated code with C compilers.
  26.  
  27. Enclosed are result of comparision between our compiler and
  28. several C compilers. All tests were made on 486DX2-66 PC.
  29. All possible optimizations for each compiler were turned on.
