/*
|
|
* Regression tests for the mono JIT.
|
|
*
|
|
* Each test needs to be of the form:
|
|
*
|
|
* public 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.
