Is this the recommended indentation? This makes it harder to read imho

Hard to say. I prefer like that but if people don't like it, I'll change it (whatever the new way is).

The previous format is fine. At some point, we'll probably switch to rustfmt and just use that, but for now we can keep it how it was.

I left a couple comments. Mostly seems okay, but the diagnostics needs a better list. Once that's fixed, I'm fine with r=me. |

@jonathandturner: I didn't change the indent (mostly because I don't which one I should use). If someone else agrees with you, I'll update. @bors: r=jonathandturner |

This failed test looks like it was caused by this PR and might be legit: https://buildbot.rust-lang.org/builders/auto-win-gnu-64-opt/builds/4710. |

It seems so. |

This PR was 6 years ahead of its time :)
Eliminate rustc_attrs::builtin::handle_errors in favor of emitting errors directly Suggested in rust-lang#116773 (review). This `handle_errors` function is originally from rust-lang#34531, in which it was useful because it allowed error messages and error codes (`E0542`) for multiple occurrences of the same error to be centralized in one place. For example rather than repeating this diagnostic in 2 places: ```rust span_err!(diagnostic, attr.span, E0542, "missing 'since'"); ``` one could repeat this instead: ```rust handle_errors(diagnostic, attr.span, AttrError::MissingSince); ``` ensuring that all "missing 'since'" errors always remained consistent in message and error code. Over time as error messages and error codes got factored to fluent diagnostics (rust-lang#100836), this rationale no longer applies. The new code has the same benefit while being less verbose (+73, -128). ```rust sess.emit_err(session_diagnostics::MissingSince { span: attr.span }); ``` r? `@cjgillot`
