2023-02-10Resolve documentation links in rustc and store the results in metadataVadim Petrochenkov-65/+54
This commit implements MCP https://github.com/rust-lang/compiler-team/issues/584 It also removes code that is no longer used, and that includes code cloning resolver, so issue #83761 is fixed.

r=compiler-errors,GuillaumeGomez Add compiler error E0523 long description and test This PR is one step towards addressing: https://github.com/rust-lang/rust/issues/61137.
2023-02-06Add extended error message for E0523Matthew Kelly-13/+6
Adds the extended error documentation for E0523 to indicate that the error is no longer produced by the compiler. Update the E0464 documentation to include example code that produces the error. Remove the error message E0523 from the compiler and replace it with an internal compiler error.

2023-02-05rustc_metadata: Refactor lazy table reading/writingVadim Petrochenkov-90/+127
Change wording from "nullable" to "default". Introduce a trait `IsDefault` for detecting values that are encoded as zeros or not encoded at all. Add panics to impossible cases. Some other minor cleanups.

2023-01-27Auto merge of #107055 - kylematsuda:eb-fn-sig, r=lcnrbors-3/+3
Switch to `EarlyBinder` for `fn_sig` query Part of the work to finish #105779 (also see https://github.com/rust-lang/types-team/issues/78). Several queries `X` have a `bound_X` variant that wraps the output in [`EarlyBinder`](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_middle/ty/subst/struct.EarlyBinder.html). This adds `EarlyBinder` to the return type of the `fn_sig` query and removes `bound_fn_sig`. r? `@lcnr`
2023-01-27Auto merge of #107054 - petrochenkov:effvisdoc3, r=GuillaumeGomezbors-0/+6
rustdoc: Collect "rustdoc-reachable" items during early doc link resolution This pass only needs to know about visibilities, attributes and reexports, so it can be run early, similarly to `compute_effective_visibilities` in rustc. Results of this pass can be used to prune the list of extern impls early thus improving performance of https://github.com/rust-lang/rust/pull/94857.
2023-01-27Rollup merge of #107171 - petrochenkov:encattrs, r=cjgillotYuki Okushi-29/+48
rustc_metadata: Fix `encode_attrs` This function didn't do what the authors intended it to do. - Due to `move` in the closure `is_public` wasn't captured by mutalbe reference and wasn't used as a cache. - Due to iterator cloning all the `should_encode_attr` logic run for the second time to calculate `may_have_doc_links` This PR fixes these issues, and calculates all the needed attribute flags in one go. (Noticed while implementing https://github.com/rust-lang/rust/pull/107136.)

2023-01-23rustc_metadata: Support non-`Option` nullable values in metadata tablesVadim Petrochenkov-76/+64
This is a convenience feature for cases in which "no value in the table" and "default value in the table" are equivalent. Tables using `Table<DefIndex, ()>` are migrated in this PR, some other cases can be migrated later. This helps `DocFlags` in https://github.com/rust-lang/rust/pull/107136 in particular.

2023-01-21rustc_metadata: Encode `doc(hidden)` flag to metadataVadim Petrochenkov-9/+46
To retrieve these flags rustdoc currently has to mass decode full attributes for items in the whole crate tree, so it's better to pre-compute it in advance. This is especially for short-term performance of https://github.com/rust-lang/rust/pull/107054 because resolver cannot use memoization of query results yet.
2023-01-21Auto merge of #106977 - michaelwoerister:unord_id_collections, r=oli-obkbors-5/+9
Use UnordMap and UnordSet for id collections (DefIdMap, LocalDefIdMap, etc) This PR changes the `rustc_data_structures::define_id_collections!` macro to use `UnordMap` and `UnordSet` instead of `FxHashMap` and `FxHashSet`. This should account for a large portion of hash-maps being used in places where they can cause trouble. The changes required are moderate but non-zero: - In some places the collections are extracted into sorted vecs. - There are a few instances where for-loops have been changed to extends. ~~Let's see what the performance impact is. With a bit more refactoring, we might be able to get rid of some of the additional sorting -- but the change set is already big enough. Unless there's a performance impact, I'd like to do further changes in subsequent PRs.~~ Performance does not seem to be negatively affected ([perf-run here](https://github.com/rust-lang/rust/pull/106977#issuecomment-1396776699)). Part of [MCP 533](https://github.com/rust-lang/compiler-team/issues/533). r? `@ghost`
