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.

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`

2022-12-28Auto merge of #106129 - compiler-errors:compare_method-tweaks, r=BoxyUwUbors-2/+2
Some `compare_method` tweaks 1. Make some of the comparison functions' names more regular 2. Reduce pub scope of some of the things in `compare_method` ~3. Remove some unnecessary opaque type handling code -- `InferCtxt` already is in a mode that doesn't define opaque types~ * moved to a different PR 4. Bubble up `ErrorGuaranteed` for region constraint errors in `compare_method` - Improves a redundant error message in one unit test. 5. Move the `compare_method` module to have a more general name, since it's more like `compare_impl_item` :) 6. Rename `collect_trait_impl_trait_tys`
