I would be surprised if it's changed a lot, but it doesn't hurt anything to check.

Finished benchmarking try commit (5e342426fd7d19b970dc77f2d1f2f1d45aee606a): comparison url.

Summary: This change led to significant improvements 🎉 in compiler performance.

  • Large improvement in instruction counts (up to -5.3% on incr-patched: println builds of coercions-check)

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. Please note that if the perf results are neutral, you should likely undo the rollup=never given below by specifying rollup- to bors.

Importantly, though, if the results of this run are non-neutral do not roll this PR up -- it will mask other regressions or improvements in the roll up.
