Move some checks from `check_doc_attrs` directly into `rustc_attr_parsing` #150934

GuillaumeGomez · 2026-01-10T17:58:04Z

Part of #149865.

I also used this opportunity to remove the id_is_crate_root method.

Once this is merged, I think I'll try to see if we can remove target_id as well.

compiler/rustc_attr_parsing/src/context.rs

    pub(crate) target_span: Span,
    /// The id ([`NodeId`] if `S` is `Early`, [`HirId`] if `S` is `Late`) of the syntactical component this attribute was applied to
    pub(crate) target_id: S::Id,
+    pub(crate) target: Option<rustc_hir::Target>,


It feels a little weird to me that target can be None, but at the same time I see getting parse_single_args to take a Target is just really annoying...
I think this is acceptable

Yeah, not sure how to deal with that. I have some ideas, gonna give it a try later on.

I thought about it more but I really don't see a nice way of fixing this, but if you do feel free to still take a look

Just a hunch, I'll see how far it leads me.

Applied suggestion for macro naming.

Finished benchmarking commit (01517e8): comparison URL.

Overall result: ❌ regressions - please read the text below

Benchmarking this pull request means it may be perf-sensitive – we'll automatically label it not fit for rolling up. You can override this, but we strongly advise not to, due to possible changes in compiler perf.

Next Steps: If you can justify the regressions found in this try perf run, please do so in sufficient writing along with @rustbot label: +perf-regression-triaged. If not, please fix the regressions and do another perf run. If its results are neutral or positive, the label will be automatically removed.
