[Experiment] Test rustc perf if compiled for x86-64-v3 #90440

hkratz · 2021-10-31T15:55:20Z

This can of course not be committed but it might be interesting too see how much perf would be gained (or lost) from AVX2 auto-vectorization and other x86-64-v3 micro-architecture optimizations.

looks like a network error

It's a cert verification failure due to another updated cert whose ca is no recognized by the ancient Debian image.

Finished benchmarking commit (039f38df1e7d4ce1f8eb3115af67107239b9173d): comparison url.

Summary: This change led to large relevant mixed results 🤷 in compiler performance.

Large improvement in instruction counts (up to -3.8% on full builds of externs)
Moderate regression in instruction counts (up to 0.6% on full builds of match-stress-enum)

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.
