URL: https://github.com/llvm/llvm-project/commit/0bd281eceff58f1e92eed6b53a33152be9810b42 DIFF: https://github.com/llvm/llvm-project/commit/0bd281eceff58f1e92eed6b53a33152be9810b42.diff LOG: CodeGen: hand two tests to the care of update_cc_test_checks These two tests were pretty challenging to manage by hand, and in rebasing the next change in my stack I finally ran out of patience and decided to just embrace automation. This change _only_ changes the tests so that it's obvious what's new in the next change.
