Fixed one of the oldest rustdoc reexport bug (5 years!) where transient crates were ignored: ``` // crate a /// a pub struct X; // crate b /// b pub use a::X // crate c /// c pub use b::X; ``` Before https://github.com/rust-lang/rust/pull/162543, the docs from the `b` crate was not present. Enjoy!

New Rust GCC backend update blog post: https://blog.antoyo.xyz/rustc_codegen_gcc-progress-report-43 A lot of improvements... that you can't enjoy yet as the cg_gcc<->Rust sync is currently blocked. ='D Enjoy!

@thierryberger.bsky.social wrote a blog post on his (great) contribution to rustdoc: https://thierryberger.com/blog/rustdoc-contribution/ Thanks for the improvement! PS: I'm now a fairy. :) 🧚

Fixed a bug in the rustdoc `--generate-macro-expansion` option (if you never tried it: https://doc.rust-lang.org/nightly/nightly-rustc/src/rustc_middle/thir.rs.html#955 or https://doc.rust-lang.org/nightly/nightly-rustc/src/rustc_middle/thir.rs.html#1010). When a same macro was generating multiple items, only the last one was visible. Not anymore! https://github.com/rust-lang/rust/pull/161876

Markdown tables have... weird handling of case separators. So much that we decided to write a rustdoc lint to prevent it: https://github.com/rust-lang/rust/pull/159583 I recommend reading the associated issue just to see how cursed it is: https://github.com/rust-lang/rust/issues/159186

The beginning of the NumBuffer API on which I worked on (and still work on) is now stable! \o/ [contains quote post or other embedded content]

New phoronix article about Rust in the Linux kernel and also about the Rust GCC backend. :) https://www.phoronix.com/news/Rust-For-Linux-7.3

(rust) Typo of the day -> `think_vec![]` (instead of `thin_vec![]`) =D

Little rustdoc bugfix: the title (the text that appears when you hover an element) of links pointing to the field of a variant didn't mention the variant. For example: `field Enum::field` instead of `field Enum::Variant::field`. PR: https://github.com/rust-lang/rust/pull/161054

Big batch of rustdoc improvements was merged today: * Emit a warning if a doc attribute is used on macro call: https://github.com/rust-lang/rust/pull/161003 * Add new `unused_footnote_definition` rustdoc lint: https://github.com/rust-lang/rust/pull/137858 * Fix/improve tables background color: https://github.com/rust-lang/rust/pull/160438 Enjoy!

Nevermind! Completely broke Rust CI (after merge, that's new, more fun for the infra team 😈 ) Reverting it. Follow me for more tips on how to make a whole project lose 3 hours of their time with one small PR! T_T [contains quote post or other embedded content]

The sync between rust and the GCC backend is done. We were a bit late there but finally caught up. Here's the PR with 224 commits (yep, you read it right ^^'): https://github.com/rust-lang/rust/pull/159844 Next cg_gcc progress report will be very interesting to read. :3 Next: why do we need to "sync"? 1/2

We just merged the fourth (big) rustdoc perf improvement in a row: https://github.com/rust-lang/rust/pull/159854: up to -39.9% https://github.com/rust-lang/rust/pull/159779: up to -19.1% https://github.com/rust-lang/rust/pull/159721: up to -28.4% https://github.com/rust-lang/rust/pull/159623: up to -31.4% All because someone encountered a weird bug when using rustdoc. \o/

Added support for "section linking" (putting an item in a specific section in the generated binary so the linker can do more optimizations) in the Rust GCC backend. 13 new Rust tests are now passing. :) PR: https://github.com/rust-lang/rustc_codegen_gcc/pull/926

The rustdoc `doc_cfg` now takes into account the `cfg_attr` predicates for macro expansion (like `derive()`). It was one of the last blockers for this feature. Not many remaining now. =D PR: https://github.com/rust-lang/rust/pull/159722

Huge perf improvement (up to 34%!) was just merged in rustdoc. Instead of handling trait impls and then filtering them, we now do the opposite. Nice side-effect: notable traits feature now works even better. PR and link to the perf report: https://github.com/rust-lang/rust/pull/159623#issuecomment-5047005618
