Finished benchmarking commit (13ea835): comparison URL. Overall result: no relevant changes - no action neededBenchmarking this pull request means it may be perf-sensitive – we'll automatically label it not fit for rolling up. You can override this, but we strongly advise not to, due to possible changes in compiler perf. @bors rollup=never Instruction countThis benchmark run did not return any relevant results for this metric. Max RSS (memory usage)This benchmark run did not return any relevant results for this metric. CyclesResults (secondary 3.5%)A less reliable metric. May be of interest, but not used to determine the overall result above.
Binary sizeThis benchmark run did not return any relevant results for this metric. Bootstrap: 476.152s -> 473.833s (-0.49%) |

Perf results show no difference, suggesting that the replacements are equivalent, as intended. @bors rollup=maybe |

Replace some `feature(core_intrinsics)` with stable hints I noticed that some compiler crates use `feature(core_intrinsics)` for optimization hints, when they could potentially be using stable `std::hint` functions instead. This PR replaces the occurrences in `rustc_arena` and `rustc_data_structures`.
