[PATCH] D96290: [tools] UpdateTestPrefix: improved verbosity

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

It comes down to us wanting the update scripts to use lists of check-prefixes for every RUN line, allowing us to share prefixes at the function level, typically getting more and more specific down the list. That way we can minimise bloat in the check lines, but still have thorough coverage with many RUNs.

With the move to avoid unused prefixes, there's going to be a lot more cases where the prefix lists need editing every time a test is changed - we need the update scripts to tell us both when a prefix becomes newly unused, but also when a run suddenly isn't checked at all.
