rust/compiler/rustc_feature/src/lib.rs, branch 1.87.0

Remove `#![warn(unreachable_pub)]` from all `compiler/` crates.

2025-03-11T02:14:21+00:00

It's no longer necessary now that `-Wunreachable_pub` is being passed.

Revert "Use workspace lints for crates in `compiler/` #138084"

2025-03-10T10:12:47+00:00

Revert to buy time to consider options that avoids breaking downstream usages of cargo on distributed `rustc-src` artifacts, where such cargo invocations fail due to inability to inherit `lints` from workspace root manifest's `workspace.lints` (this is only valid for the source rust-lang/rust workspace, but not really the distributed `rustc-src` artifacts). This breakage was reported in . This reverts commit 48caf81484b50dca5a5cebb614899a3df81ca898, reversing changes made to c6662879b27f5161e95f39395e3c9513a7b97028.

Remove `#![warn(unreachable_pub)]` from all `compiler/` crates.

2025-03-07T21:41:43+00:00

(Except for `rustc_codegen_cranelift`.) It's no longer necessary now that `unreachable_pub` is in the workspace lints.

rustc_feature: Avoid unsafe `std::env::set_var()` in `UnstableFeatures` tests

2025-01-08T10:37:19+00:00

Avoid unsafe `std::env::set_var()` by allowing tests to inject `std::env::var("RUSTC_BOOTSTRAP")` with a `env_var_rustc_bootstrap` parameter.

Re-export more `rustc_span::symbol` things from `rustc_span`.

2024-12-18T02:38:53+00:00

`rustc_span::symbol` defines some things that are re-exported from `rustc_span`, such as `Symbol` and `sym`. But it doesn't re-export some closely related things such as `Ident` and `kw`. So you can do `use rustc_span::{Symbol, sym}` but you have to do `use rustc_span::symbol::{Ident, kw}`, which is inconsistent for no good reason. This commit re-exports `Ident`, `kw`, and `MacroRulesNormalizedIdent`, and changes many `rustc_span::symbol::` qualifiers in `compiler/` to `rustc_span::`. This is a 200+ net line of code reduction, mostly because many files with two `use rustc_span` items can be reduced to one.

Add `RUSTC_BOOTSTRAP=-1` to make rustc pretend as stable compiler

Introduce `Enabled{Lang,Lib}Feature`

2024-10-25T02:30:37+00:00

Instead of passing around random n-tuples of e.g. `(gate_name, attr_sp, since)`.

rename lang feature lists to include LANG

remove no longer needd UnstableFeature type

2024-10-23T08:14:43+00:00
