I would've expected import changes as well - is this coming from a macro or something like that? If so that should get a allow_internal_unstable annotation instead, probably

I am not exactly sure what you are referring to, but in src/librustc_interface/passes.rs and src/librustc_interface/queries.rs the code imports OnceCell re-exported from librustc_datastructures.
Side note: there is also an explicit import (and thus a dependency on the crate) of once_cell::sync::OnceCell in src/librustc_interface/util.rs though and I don't know if that should be updated to use the impl from std.

Finished benchmarking try commit (e1c8714b3f420be20f3c670b7ad84eccbe252b26): comparison url. 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 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. @bors rollup=never |

Nice, basically no change in instructions but significantly less max-rss :) |
|
@jyn514 think that it is to little data to say anything about the max-rss due to how big the variance is if you look at perf graphs you will see that eg. keccak-debug have varied between -10% to +20%. |
|
Yeah, I would be very surprised if the perf turned out to be non-neutral on this one ! @bors r+ rollup Let’s change direct usages of once_cell and lazy_static crates to std::lazy in a separate PR. I am not sure about the policy of using librustc_datastructures re-export vs direct use, but it should always be safe to not change this particular aspect. |

We might need a perf run for this change.
