# 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.
