5 * Regression tests for the mono JIT.
7 * Each test needs to be of the form:
9 * static int test_<result>_<name> ();
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.
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)
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
