   5  * Regression tests for the mono JIT.
   6  *
   7  * Each test needs to be of the form:
   8  *
   9  * public static int test_<result>_<name> ();
  10  *
  11  * where <result> is an integer (the value that needs to be returned by
  12  * the method to make it pass.
  13  * <name> is a user-displayed name used to identify the test.
  14  *
  15  * The tests can be driven in two ways:
  16  * *) running the program directly: Main() uses reflection to find and invoke
  17  *      the test methods (this is useful mostly to check that the tests are correct)
  18  * *) with the --regression switch of the jit (this is the preferred way since
  19  *      all the tests will be run with optimizations on and off)
  20  *
  21  * The reflection logic could be moved to a .dll since we need at least another
  22  * regression test file written in IL code to have better control on how
  23  * the IL code looks.
