2022-01-06rustc_metadata: Split `fn get_implementations_for_trait` into two functionsVadim Petrochenkov-22/+22
2022-01-06rustc_metadata: Make `opt_item_ident` in decoder faster and stricterVadim Petrochenkov-33/+24
By avoiding formatting and allocations in the no-ident case, and by making the span mandatory if the ident exists. Use the optimized `opt_item_ident` to cleanup `fn each_child_of_item`
2022-01-06rustc_metadata: Make attribute decoding slightly faster and stricterVadim Petrochenkov-13/+15
Rename `CStore::item_attrs` -> `CStore::item_attrs_untracked` top follow conventions
2022-01-06rustc_middle: Add a method for getting a `SimplifiedType` definition/IDVadim Petrochenkov-3/+3
Import `SimplifiedType` more
2022-01-02Auto merge of #92034 - petrochenkov:nolinknores, r=joshtriplettbors-9/+1
Remove effect of `#[no_link]` attribute on name resolution Previously it hid all non-macro names from other crates. This has no relation to linking and can change name resolution behavior in some cases (e.g. glob conflicts), in addition to just producing the "unresolved name" errors. I can kind of understand the possible reasoning behind the current behavior - if you can use names from a `no_link` crates then you can use, for example, functions too, but whether it will actually work or produce link-time errors will depend on random factors like inliner behavior. (^^^ This is not the actual reason why the current behavior exist, I've looked through git history and it's mostly accidental.) I think this risk is ok for such an obscure attribute, and we don't need to specifically prevent use of non-macro items from such crates. (I'm not actually sure why would anyone use `#[no_link]` on a crate, even if it's macro only, if you aware of any use cases, please share. IIRC, at some point it was used for crates implementing custom derives - the now removed legacy ones, not the current proc macros.) Extracted from https://github.com/rust-lang/rust/pull/91795.
2022-01-01rustc_metadata: Use a query for collecting all traits in encoderVadim Petrochenkov-1/+2
2021-12-29Auto merge of #92244 - petrochenkov:alltraits, r=cjgillotbors-0/+4
rustc_metadata: Encode list of all crate's traits into metadata While working on https://github.com/rust-lang/rust/pull/88679 I noticed that rustdoc is casually doing something quite expensive, something that is used only for error reporting in rustc - collecting all traits from all crates in the dependency tree. This PR trades some minor extra time spent by metadata encoder in rustc for major gains for rustdoc (and for rustc runs with errors, which execute the `all_traits` query for better diagnostics).

2021-12-28rustc_metadata: Merge items from `extern` blocks into their parent modulesVadim Petrochenkov-36/+5
during metadata encoding rather than during metadata decoding
2021-12-22rustc_metadata: Merge `get_ctor_def_id` and `get_ctor_kind`Vadim Petrochenkov-19/+17
Also avoid decoding the whole `ty::AssocItem` to get a `has_self` flag

2021-11-09Add `ty::Visibility::is_public()`inquisitivecrystal-1/+1
2021-10-28Remove `ModData` from rustc_metadataMatthew Jasper-2/+2
This avoids having to decode 2 `Lazy`s when decoding a modules exports.
2021-10-21Handle cross-crate module `ExpnId`s consistentlyMatthew Jasper-4/+5
- Always use the ExpnId serialized to `tables` - Use the Id for traits and enums from other crates in resolution.
2021-10-16Adopt let_else across the compilerest31-3/+1
This performs a substitution of code following the pattern: let <id> = if let <pat> = ... { identity } else { ... : ! }; To simplify it to: let <pat> = ... { identity } else { ... : ! }; By adopting the let_else feature.
2021-10-07Rollup merge of #89476 - cjgillot:expn-id, r=petrochenkovJubilee-4/+2
Correct decoding of foreign expansions during incr. comp. Fixes https://github.com/rust-lang/rust/issues/74946 The original issue was due to a wrong assertion in `expn_hash_to_expn_id`. The secondary issue was due to a mismatch between the encoding and decoding paths for expansions that are created after the TyCtxt is created.
2021-10-06Do not ICE if some foreign expansions were not encoded.Camille GILLOT-2/+0
The metadata encoder does not necessarily encode all expansions, only those which are referenced in other metadata fields.

DefPathHashMap in rustc_hir.
2021-09-14Make DefPathHash->DefId panic for if the mapping fails.Michael Woerister-1/+1
We only use this mapping for cases where we know that it must succeed. Letting it panic otherwise makes it harder to use the API in unsupported ways.
2021-09-14Store DefPathHash->DefIndex map in on-disk-hash-table format in crate metadata.Michael Woerister-57/+18
This encoding allows for random access without an expensive upfront decoding state which in turn allows simplifying the DefPathIndex lookup logic without regressing performance.
2021-09-14Allow taking an OwningRef of the crate metadata blob.Michael Woerister-17/+61
2021-09-12Rollup merge of #88709 - BoxyUwU:thir-abstract-const, r=lcnrManish Goregaokar-4/+5
generic_const_exprs: use thir for abstract consts instead of mir Changes `AbstractConst` building to use `thir` instead of `mir` so that there's less chance of consts unifying when they shouldn't because lowering to mir dropped information (see `abstract-consts-as-cast-5.rs` test) r? `@lcnr`
