Finished benchmarking commit (826335d7ca7f2dac1507ef05f329437f4ebe6caf): comparison url.

Summary: This change led to moderate relevant regressions 😿 in compiler performance.

  • Moderate regression in instruction counts (up to 1.1% on incr-patched: b9b3e592dd cherry picked builds of style-servo)

If you disagree with this performance assessment, please file an issue in rust-lang/rustc-perf.

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 led 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.

Finished benchmarking commit (22f8bde): comparison url.

Summary: This change led to large relevant regressions 😿 in compiler performance.

  • Large regression in instruction counts (up to 3.1% on full builds of inflate)

If you disagree with this performance assessment, please file an issue in rust-lang/rustc-perf.

Next Steps: If you can justify the regressions found in this perf run, please indicate this with @rustbot label: +perf-regression-triaged along with sufficient written justification. If you cannot justify the regressions please open an issue or create a new PR that fixes the regressions, add a comment linking to the newly created issue or PR, and then add the perf-regression-triaged label to this PR.

@rustbot label: +perf-regression-triaged

The only change between the last perf triage comment and the regression after the merge is a rebase. The exact cause is unknown, but I'm speculating CGU division and/or inlining differences. The regressions aren't "noise", but some of them are not related to the visible changes this PR has. this is like #87688 (comment), but the exact details could differ.
