2021-09-30Use `Path` instead of `Type` in `PolyTrait`Noah Lev-14/+18
The change to `impl Clean<Path> for hir::TraitRef<'_>` was necessary to fix a test failure for `src/test/rustdoc/trait-alias-mention.rs`. Here's why: The old code path was through `impl Clean<Type> for hir::TraitRef<'_>`, which called `resolve_type`, which in turn called `register_res`. Now, because `PolyTrait` uses a `Path` instead of a `Type`, the impl of `Clean<Path>` was being run, which did not call `register_res`, causing the trait alias to not be recorded in the `external_paths` cache.
2021-09-30Make `Impl.trait_` a `Path`, not a `Type`Noah Lev-1/+6
It should only ever be a `ResolvedPath`, so this (a) enforces that, and (b) reduces the size of `Impl`. I had to update a test because the order of the rendered auto trait impl bounds changed. I think the order changed because rustdoc sorts auto trait bounds using their `Debug` output.

2021-09-12Fix broken handling of primitive itemsJoshua Nelson-3/+1
- Fix broken handling of primitive associated items - Remove fragment hack Fixes 83083 - more logging - Update CrateNum hacks The CrateNum has no relation to where in the dependency tree the crate is, only when it's loaded. Explicitly special-case core instead of assuming it will be the first DefId. - Update and add tests - Cache calculation of primitive locations This could possibly be avoided by passing a Cache into collect_intra_doc_links; but that's a much larger change, and doesn't seem valuable other than for this.
2021-09-05Auto merge of #88604 - camelid:rustdoc-lifetime-bounds, r=GuillaumeGomezbors-2/+4
rustdoc: Clean up handling of lifetime bounds Previously, rustdoc recorded lifetime bounds by rendering them into the name of the lifetime parameter. Now, it leaves the name as the actual name and instead records lifetime bounds in an `outlives` list, similar to how type parameter bounds are recorded. Also, higher-ranked lifetimes cannot currently have bounds, so I simplified the code to reflect that. r? `@GuillaumeGomez`

2021-09-02Auto merge of #88522 - camelid:box-paren-output, r=jyn514bors-1/+1
rustdoc: Box `GenericArgs::Parenthesized.output` Split out from #88379. This reduces the size of `GenericArgs` from 104 bytes to 56 bytes, essentially reducing it by half. `GenericArgs` is one of the fields of `PathSegment`, so this should reduce the amount of memory allocated for `PathSegment`s in the cases where the generics are not for a `Fn`, `FnMut`, or `FnOnce` trait. r? `@jyn514`

I also added `static_assert_size!`s to `GenericArgs` and `PathSegment` to ensure they don't increase in size unexpectedly.

2021-05-14Box `Impl.blanket_impl` to reduce sizeNoah Lev-1/+1
Blanket impls are probably not super common, and `Type` is a fairly large type, so this should reduce `Impl`'s size by a lot: `Option<Type>` is around 96 bytes, and `Option<Box<Type>>` is 8 bytes, so it's a big difference!
2021-05-12Auto merge of #83813 - cbeuw:remap-std, r=michaelwoeristerbors-12/+11
Fix `--remap-path-prefix` not correctly remapping `rust-src` component paths and unify handling of path mapping with virtualized paths This PR fixes #73167 ("Binaries end up containing path to the rust-src component despite `--remap-path-prefix`") by preventing real local filesystem paths from reaching compilation output if the path is supposed to be remapped. `RealFileName::Named` introduced in #72767 is now renamed as `LocalPath`, because this variant wraps a (most likely) valid local filesystem path. `RealFileName::Devirtualized` is renamed as `Remapped` to be used for remapped path from a real path via `--remap-path-prefix` argument, as well as real path inferred from a virtualized (during compiler bootstrapping) `/rustc/...` path. The `local_path` field is now an `Option<PathBuf>`, as it will be set to `None` before serialisation, so it never reaches any build output. Attempting to serialise a non-`None` `local_path` will cause an assertion faliure. When a path is remapped, a `RealFileName::Remapped` variant is created. The original path is preserved in `local_path` field and the remapped path is saved in `virtual_name` field. Previously, the `local_path` is directly modified which goes against its purpose of "suitable for reading from the file system on the local host". `rustc_span::SourceFile`'s fields `unmapped_path` (introduced by #44940) and `name_was_remapped` (introduced by #41508 when `--remap-path-prefix` feature originally added) are removed, as these two pieces of information can be inferred from the `name` field: if it's anything other than a `FileName::Real(_)`, or if it is a `FileName::Real(RealFileName::LocalPath(_))`, then clearly `name_was_remapped` would've been false and `unmapped_path` would've been `None`. If it is a `FileName::Real(RealFileName::Remapped{local_path, virtual_name})`, then `name_was_remapped` would've been true and `unmapped_path` would've been `Some(local_path)`. cc `@eddyb` who implemented `/rustc/...` path devirtualisation
