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