There are a number of testing strategies:


* test that correct C programs are compiled correctly.
* test that incorrect C programs are diagnosed correctly.
* test that correct C programs will compile and run, producing
a result at their termination that can be tested for.
* test that old bugs, once fixed, do not reappear.


The GCC testsuite would be an excellent starting point for testing
your cross-compiler, as the thousands of test cases have already been written.


Conformance testsuites also exist, although they do not come cheaply.
