`compiler_builtins` shouldn't be called directly. Change the `PartialEq` implementation for `DevicePathNode` to use slice equality instead, which will call `memcmp`/`bcmp` via the intrinsic.

The three panic-related library crates need to have access to `core`, and `compiler-builtins` needs to be in the crate graph. Rather than specifying both dependencies, switch these crates to use `rustc-std-workspace-core` which already does this. This means there is now a single place that the `compiler-builtins` dependency needs to get configured, for everything other than `alloc` and `std`.

`compiler-builtins` is already in the crate graph via `alloc`, and all features related to `compiler-builtins` goes through `alloc`. There isn't any reason that `std` needs this direct dependency, so remove it.

Changes to `compiler-builtins` don't currently get a `T-` label, but it is mostly managed by libs. Add the autolabel here.

…e, r=bjorn3,Noratrieb Simplify library dependencies on `compiler-builtins` The three panic-related library crates need to have access to `core`, and `compiler-builtins` needs to be in the crate graph. Rather than specifying both dependencies, switch these crates to use `rustc-std-workspace-core` which already does this. This means there is now a single place that the `compiler-builtins` dependency needs to get configured, for everything other than `alloc` and `std`. The second commit removes `compiler-builtins` from `std` (more details in the message).

…r=lqd Ping Muscraft when emitter change While I am working towards `annotate-snippets` being the default emitter for `rustc`, it would be helpful if I were pinged when the default emitter is modified so that I can more easily maintain parity in output between `rustc` and `annotate-snippets`.

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.

Finished benchmarking commit (e3ee7f7): comparison URL.

Overall result: ❌✅ regressions and improvements - please read the text below

Our benchmarks found a performance regression caused by this PR.
This might be an actual regression, but it can also be just noise.

Next Steps:

If the regression was expected or you think it can be justified,
please write a comment with sufficient written justification, and add
@rustbot label: +perf-regression-triaged to it, to mark the regression as triaged.
If you think that you know of a way to resolve the regression, try to create
a new PR with a fix for the regression.
If you do not understand the regression or you think that it is just noise,
you can ask the @rust-lang/wg-compiler-performance working group for help (members of this group
were already notified of this PR).

Maybe #143849

panstromek · 2025-08-04T13:42:44Z

perf triage:

doc regression on various benchmarks.

Maybe #143849

I think so. Based on detailed results, it's in the def_kind query, and #143849 adds a callsite. Other PRs look mostly unrelated (few triagebot and config changes, confusables improvement, minor rustdoc-json change).
