It also adds support for auto-fixing tests failing based on the diff command.

This seems like an independent feature -- do it as a followup?

Will do

This reverts commit e495231 to reland the --update-tests feature, originally landed in llvm#108425.

Deferred the diff test update changes to #154147

nikic · 2025-08-19T12:39:32Z

It looks like this also ends up regenerating XFAIL tests, which is not desirable.

It looks like this also ends up regenerating XFAIL tests, which is not desirable.

Thanks for letting me know! Will address in a follow up once #154147 is merged since that makes it easier to write test cases.

Thanks for relanding this, it's super useful. It seems to rerun update_test_checks.py on tests that weren't failing, which can cause some spurious diffs that are just UTC regens. Is it possible to restrict this to only update the tests that failed?

Are these XFAIL tests, or just normal tests that passed?

Just normal tests that passed. Is this intentional?

Definitely not. I'll take a look.

Thanks! If it's of any help, here's one test where running./build/bin/llvm-lit --update-tests llvm/test/Transforms/LoopVectorize/AArch64/conditional-branches-cost.ll seems to cause a spurious update on my end.
