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