Rust Compiler Performance Triage

A good week overall, with a broad set of improvements to many primary benchmarks. The main single source of primary regressions is from rollup PR #111869; we are in the process of narrowing that down to see if there is a root cause.

Triage done by @pnkfelix. Revision range: cda5becc..1221e43b

3 Regressions, 3 Improvements, 3 Mixed; 4 of them in rollups 26 artifact comparisons made in total

Approved RFCs

Changes to Rust follow the Rust RFC (request for comments) process. These are the RFCs that were approved for implementation this week:

The #[diagnostic] attribute namespace

Final Comment Period

Every week, the team announces the 'final comment period' for RFCs and key PRs which are reaching a decision. Express your opinions now.

Call for Testing

An important step for RFC implementation is for people to experiment with the implementation and give feedback, especially before stabilization. The following RFCs would benefit from user testing before moving forward:

Add a [lints] table to Cargo.toml (Feature: manifest-lint)
- Tracking Issue
- Testing steps

If you are a feature implementer and would like your RFC to appear on the above list, add the new call-for-testing label to your RFC along with a comment providing testing instructions and/or guidance on which aspect(s) of the feature need testing.
