I think the CI is [failing](https://buildkite.com/llvm-project/github-pull-requests/builds/66150#018f9dc9-4a21-4ae2-bfde-bfd9947b1456) on the new `call-latency.s` test you added. It seems like there is a mismatch on the number of uOps so you might want to rerun update_mca_check.py again and/or rebase in case there is any change on uOps in the scheduling model.

Note that passing (pre-commit) CI is not a requirement for merging PR in LLVM but it'll be easier to address any issue early, otherwise 10+ (post-commit) buildbots might flood you with build failure emails after merge.
