Remove `Ident::empty`.

2025-05-09T03:57:49+00:00

All uses have been removed. And it's nonsensical: an identifier by definition has at least one char. The commits adds an is-non-empty assertion to `Ident::new` to enforce this, and converts some `Ident` constructions to use `Ident::new`. Adding the assertion requires making `Ident::new` and `Ident::with_dummy_span` non-const, which is no great loss. The commit amends a couple of places that do path splitting to ensure no empty identifiers are created.

Handle `rustc_middle` cases of `rustc::potential_query_instability` lint This PR removes `#![allow(rustc::potential_query_instability)]` line from [`compiler/rustc_middle/src/lib.rs`](https://github.com/rust-lang/rust/blob/master/compiler/rustc_middle/src/lib.rs#L29) and converts `FxHash{Map,Set}` types into `FxIndex{Map,Set}` to suppress lint errors. A somewhat tracking issue: https://github.com/rust-lang/rust/issues/84447 r? `@compiler-errors`

Auto merge of #140453 - Zoxc:next-disambiguator, r=oli-obk

2025-05-05T11:50:43+00:00

Remove global `next_disambiguator` state and handle it with a `DisambiguatorState` type This removes `Definitions.next_disambiguator` as it doesn't guarantee deterministic def paths when `create_def` is called in parallel. Instead a new `DisambiguatorState` type is passed as a mutable reference to `create_def` to help create unique def paths. `create_def` calls with distinct `DisambiguatorState` instances must ensure that that the def paths are unique without its help. Anon associated types did rely on this global state for uniqueness and are changed to use (method they're defined in + their position in the method return type) as the `DefPathData` to ensure uniqueness. This also means that the method they're defined in appears in error messages, which is nicer. `DefPathData::NestedStatic` is added to use for nested data inside statics instead of reusing `DefPathData::AnonConst` to avoid conflicts with those. cc `@oli-obk`

Simplify `LazyAttrTokenStream`.

2025-04-29T21:10:56+00:00

This commit does the following. - Changes it from `Lrc>` to `Lrc`. - Reworks `LazyAttrTokenStreamImpl` as `LazyAttrTokenStreamInner`, which is a two-variant enum. - Removes the `ToAttrTokenStream` trait and the two impls of it. The recursion limit must be increased in some crates otherwise rustdoc aborts.

Rollup merge of #139084 - petrochenkov:transpaque, r=davidtwco

2025-04-16T22:14:24+00:00

hygiene: Rename semi-transparent to semi-opaque "Semi-transparent" is just too damn long for a name, especially when used multiple times on a single line, it bothered me when working on #139083. An optimist sees a macro as semi-opaque, a pessimist sees it as semi-transparent. Or is it the other way round?
