| # This test used to assert in RABasic. The problem was when we split live-ranges, |
| # we were not updating the LiveRegMatrix properly and the interference calculation |
| # wouldn't match what the assignment thought it could do. |
| # In other words, this test case needs to trigger live-range splitting to exercise |
| # the problem. |
