 *               Guided Optimization.  
 *
 *               Read incoming data from address 0xFFD00000 and count the 
 *               number of even values and odd values.  Supplying data files 
 *               with varying numbers of odd values vs. even values will 
 *               direct the compiler to optimize the conditional statement 
 *               with a bias for the branch most likely to be taken.
