- * \brief Generate the table used in the fast_output_map function.
- *
- * The table has 16K byte entries, but because of how is is used, only
- * 256 entries end up being resident in the cache.  This seems
- * like a good use of memory.  We can get away with a 16K table
- * because the low two bits of the state do not affect the output
- * function.  By shifting right those two bits we shrink the table,
- * and also get better cache line utilization.
