Test cases missing / or verification not done

[dennisguse]

Some included programs provide either not test cases or only verification.

This includes the following tools / folders:

• basop (no tests)
• basop/flc (no tests)
• eid (no verification)
• freqresp (only one test with verification)
• is54 (no verification)
• mnru/snr (no verification)
• reverb (only one test with verification)
• sv56 (only two test cases)
• unsup/* (some test cases; might not be necessary to add more tests)

Dennis - Some comments: * basop (no tests) -> no demo program, so no tests were provided by design * basop/flc (no tests) -> idem * eid (no verification) * freqresp (only one test with verification) * is54 (no verification) -> This codec has inherent problems with single float resolution and divergence of results over time for executables produced in different platforms, hence no meaningful verification can be provided. Only simple portability checking for the code itself, but the implementation itself is inherently "not portable" because different architectures implement float differently that leads to accumulation of errors in the mathematical operations of the code and divergence – although the decoded speech sounds the same. * mnru/snr (no verification) -> supporting tool within the MNRU tool, not really part of it (could be seen as belonging to the unsup group) * reverb (only one test with verification) * sv56 (only two test cases) -> verification was done at time of implementation with subjective and objective tests (COM 15-182-E, 1993-1996), not practical for inclusion in the code. * unsup/* (some test cases; might not be necessary to add more tests)
