Unrolled build for rust-lang#134481

rust-timer · web-flow · commit 08953042ebf1 · 2024-12-19T03:32:51.000-05:00
Rollup merge of rust-lang#134481 - estebank:unstable-lint-span, r=compiler-errors Point at lint name instead of whole attr for gated lints ``` warning: unknown lint: `test_unstable_lint` --> $DIR/warn-unknown-unstable-lint-inline.rs:4:10 | LL | #![allow(test_unstable_lint, another_unstable_lint)] | ^^^^^^^^^^^^^^^^^^ | = note: the `test_unstable_lint` lint is unstable = help: add `#![feature(test_unstable_lint)]` to the crate attributes to enable = note: this compiler was built on YYYY-MM-DD; consider upgrading it if it is out of date note: the lint level is defined here --> $DIR/warn-unknown-unstable-lint-inline.rs:3:9 | LL | #![warn(unknown_lints)] | ^^^^^^^^^^^^^ warning: unknown lint: `test_unstable_lint` --> $DIR/warn-unknown-unstable-lint-inline.rs:4:29 | LL | #![allow(test_unstable_lint, another_unstable_lint)] | ^^^^^^^^^^^^^^^^^^^^^ | = note: the `another_unstable_lint` lint is unstable = help: add `#![feature(another_unstable_lint)]` to the crate attributes to enable = note: this compiler was built on YYYY-MM-DD; consider upgrading it if it is out of date ``` This is particularly relevant when there are multiple lints in the same `warn` attribute. Pointing at the smaller span makes it clearer which one the warning is complaining about.
