                         Benchmarks


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

The directory samples\simple contains the following benchmark
programs:

        dry.mod         Drystone  (Modula-2)
        dry.c           Drystone  (C)
        whet.mod        Whetstone (Modula-2)
        linnew.mod      LinPack   (Modula-2)
        linnew.c        LinPack   (C)

These tests can be used to compare different platforms and different
compilers.  We include C sources to make it possible to compare the
quality of the generated code with C compilers.

Enclosed are result of comparision between our compiler and
several C compilers. All tests were made on 486DX2-66 PC.
All possible optimizations for each compiler were turned on.
