I'm not sure this is the right approach here. If we get a jraddiusp then the problem that the test is trying to cover can't possibly happen anyway. (The test is checking if a load and final stack adjustment are ever re-ordered from what I can see.) I'd just mark the test as NOCOMPRESSION instead of just NOMIPS16 and update the comment to say that it is avoiding SAVE, RESTORE and JRADDIUSP. Thanks, Matthew
