Overall result: ❌ regressions - no 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.

@scottmcm looks like this may have been fixed a couple of days ago rust-lang/stdarch#1630

[scottmcm]

Updated to rust-lang/stdarch@d9466ed to pick up rust-lang/stdarch#1630 that fixed the dist-loongarch64-linux problem.

(And hopefully with rust-lang/stdarch#1631, these problems will be caught in stdarch CI in future, rather than here.)

Mostly doc builds that get slower when core/std are updated.

Visiting for weekly perf triage.

• primary regressions are to cratelift-codegen llvm-opt-full and helloworld llvm-doc-full
• from the graphs, the cranelift regression looks like a blip, and the helloworld regression seems tiny compared to other changes in its history -- I infer the auto-computed significance threshold is quite low here, probably because historically the build time for helloworld is very stable?
• In any case, doesn't seem worth investigating. Marking as triaged.
