----------------
If you change the run line to this, you can use utils/update_llc_test_checks.py to autogenerate the test output, which will make it easier for me to understand the transformation we are doing. Also, it looks like the code is more general than it needs to be to handle this one case. Is there an opportunity to either simplify the code or test more cases here?
