I did think about the same idea, by putting the code into test codebase or generate the tables with makefile configuration.   Actually, I had the table generation code in my local workspace.  However, I give it up at last because such kind of code is just used one time and may not worthy the resources to maintain it or the power to run it while building/testing.  None of the tables could be wrong, otherwise the algorithm will not work.  The regression test and inter-op testing may be sufficient to approve that the tables are good.

But please let me know, if you have a strong preference to have it, I will try to integrate the table generation code.
