* rand() use XOR to break up unwanted pair correlation This form of rand() cannot return the same value twice in a row. Two additonal EOR instructions produce a more even distribution of successive pairs. see comments on #951 * rand.s document purpose of XOR * suggested srand() optimization: zero fill unnecessary * test to validate implementation of rand() * srand() improving behaviour and adding startup test * srand() with a tail call to rand() for better initial shuffle * srand() can fall through to rand() instead of tail call
