Mention Clone and refererences, and use more realistic examples (within the constraints of a few lines :).
Old LLVM bugs are reportedly cropping up harder, but 3.9 seems to be OK. Fixes rust-lang#45277.
The necessary changes were only in upstream LLVM in 4.0, but they were for a while backported to Rust LLVM. Now that Rust LLVM is also 4.0, we can make the test conditional here more accurate.
While the `config.toml.example` comments say "we automatically check the version by default," we actually didn't. That check was badly out of date, only allowing 3.5, 3.6, or 3.7. This it now updated to the new 3.9 minimum requirement, and truly enabled by default.
Part of rust-lang#44136 Upgrades cargo due to rust-lang/cargo#4451
The process for updating rustfmt is quite involved because of the way everything is configured. This section covers the steps for updating rustfmt and rationale behind them.
In `src/libstd/primitive_docs.rs`, a `#[doc(primitive = "unit")]` section has sat long neglected. This patch teaches rustdoc to recognize "unit", and steals its trait implementations away from the tuple page.
…r=QuietMisdreavus Deprecate several flags in rustdoc Part of rust-lang#44136 cc @rust-lang/dev-tools @rust-lang/docs This is a very basic PR to start deprecating some flags; `rustdoc` doesn't really have fancy output options like `rustc` does, so I went with `eprintln!`. Happy to change it if people feel that's not appropriate. Also, I have no idea if we can or should write tests here, so I didn't try. If someone feels strongly about it, then let's do it, but given that the only outcome here is a side effect...
Mention Clone and refs in --explain E0382 I followed the discussion in rust-lang#42446 and came up with these additions. - Mention references before going into traits. They're probably more likely solutions. - Mention `Clone` before `Copy`. Cloning has wider applicability and `#derive[Copy, Clone]` makes more sense after learning about `Clone`. The language is not great, any suggestions there would be appreciated ✨
…ichton Documenting the process for when rustfmt/rls break **DO NOT MERGE YET** I'm documenting what to do when rustfmt or rls break because of your changes. I'm currently going through this and will keep adding more as I figure out what all the steps are. This first commit is based on @alexcrichton's [comment on my original PR](rust-lang#44766 (comment)). [Rendered](https://github.com/sunjay/rust/blob/breakingrustfmtrls/CONTRIBUTING.md#breaking-tools-built-with-the-compiler) Reviews are welcome, but as I mentioned, I will be revising this as I go.
…ewsxcv List of all lang items in unstable book. I don't know how to link to the source code correctly, so I just put the information aside the lang item name.
Fix out of date unstable book entries for `alloc_*` features. The `alloc_jemalloc` crate does not provide a type to use with `#[global_allocator]`, and (according to Alex) `extern crate alloc_jemalloc;` alone became a no-op when `#[global_allocator]` was introduced.

Bump the minimum LLVM to 3.9 Old LLVM bugs are reportedly cropping up harder, but 3.9 seems to be OK. Fixes rust-lang#45277.
…initialized, r=alexcrichton Docs: a LocalKey might start in the Valid state Add a comment to the docs for `LocalKey::state` explaining that some keys might skip the `Uninitialized` state and start in the `Valid` state. cc rust-lang#27716 r? @alexcrichton
rustdoc: add a primitive page for "unit" In `src/libstd/primitive_docs.rs`, a `#[doc(primitive = "unit")]` section has sat long neglected. This patch teaches rustdoc to recognize "unit", and steals its trait implementations away from the tuple page.
