Overall result: ❌✅ regressions and improvements - ACTION NEEDED

Benchmarking this pull request likely means that it is perf-sensitive, so we're automatically marking it as not fit for rolling up. While you can manually mark this PR as fit for rollup, we strongly recommend not doing so since this PR may lead to changes in compiler perf.

Next Steps: If you can justify the regressions found in this try perf run, please indicate this with @rustbot label: +perf-regression-triaged along with sufficient written justification. If you cannot justify the regressions please fix the regressions and do another perf run. If the next run shows neutral or positive results, the label will be automatically removed.

I think this needs #115613 in order to not be a perf regression in some incremental cases

I think this needs #115613 in order to not be a perf regression in some incremental cases

On the contrary, I think this is due to spans not being marked relative, as lowering does it.

@bvanjoi any updates on this? thanks

bvanjoi · 2024-02-19T15:52:00Z

This PR was intended to feed the span during resolution, but it unexpectedly caused a performance regression in mir_borrowck under incremental builds. Unfortunately, I'm uncertain on how to debug it locally to find an appropriate solution.

@cjgillot Do you have any thoughts or suggestions regarding this? If not, I may consider closing it...

(Perhaps we could rerun this performance test, as I have addressed the previous comments?)

🔒 Merge conflict

This pull request and the master branch diverged in a way that cannot be automatically merged. Please rebase on top of the latest master branch, and let the reviewer approve again.

How do I rebase?

Assuming self is your fork and upstream is this repository, you can resolve the conflict following these steps:

git checkout fix-118552 (switch to your branch)
git fetch upstream master (retrieve the latest master)
git rebase upstream/master -p (rebase on top of it)
Follow the on-screen instruction to resolve conflicts (check git status if you got lost).
git push self fix-118552 --force-with-lease (update this PR)

You may also read Git Rebasing to Resolve Conflicts by Drew Blessing for a short tutorial.

Please avoid the "Resolve conflicts" button on GitHub. It uses git merge instead of git rebase which makes the PR commit history more difficult to read.

Sometimes step 4 will complete without asking for resolution. This is usually due to difference between how Cargo.lock conflict is handled during merge and rebase. This is normal, and you should still perform step 5 to update this PR.
