allow `#[rustc_align_static(N)]` on `static`s

2025-09-09T19:54:54+00:00

We need a different attribute than `rustc_align` because unstable attributes are tied to their feature (we can't have two unstable features use the same unstable attribute). Otherwise this uses all of the same infrastructure as `#[rustc_align]`.

On unused binding or binding not present in all patterns, suggest potential typo of unit struct/variant or const When encountering an or-pattern with a binding not available in all patterns, look for consts and unit struct/variants that have similar names as the binding to detect typos. ``` error[E0408]: variable `Ban` is not bound in all patterns --> $DIR/binding-typo.rs:22:9 | LL | (Foo, _) | (Ban, Foo) => {} | ^^^^^^^^ --- variable not in all patterns | | | pattern doesn't bind `Ban` | help: you might have meant to use the similarly named unit variant `Bar` | LL - (Foo, _) | (Ban, Foo) => {} LL + (Foo, _) | (Bar, Foo) => {} | ``` For items that are not in the immedate scope, suggest the full path for them: ``` error[E0408]: variable `Non` is not bound in all patterns --> $DIR/binding-typo-2.rs:51:16 | LL | (Non | Some(_))=> {} | --- ^^^^^^^ pattern doesn't bind `Non` | | | variable not in all patterns | help: you might have meant to use the similarly named unit variant `None` | LL - (Non | Some(_))=> {} LL + (core::option::Option::None | Some(_))=> {} | ``` When encountering a typo in a pattern that gets interpreted as an unused binding, look for unit struct/variant of the same type as the binding: ``` error: unused variable: `Non` --> $DIR/binding-typo-2.rs:36:9 | LL | Non => {} | ^^^ | help: if this is intentional, prefix it with an underscore | LL | _Non => {} | + help: you might have meant to pattern match on the similarly named variant `None` | LL - Non => {} LL + std::prelude::v1::None => {} | ``` Suggest constant on unused binding in a pattern ``` error: unused variable: `Batery` --> $DIR/binding-typo-2.rs:110:9 | LL | Batery => {} | ^^^^^^ | help: if this is intentional, prefix it with an underscore | LL | _Batery => {} | + help: you might have meant to pattern match on the similarly named constant `Battery` | LL | Battery => {} | + ``` Fix rust-lang/rust#51976.

On unused binding in pattern, suggest unit struct/variant with similar name

When encountering a typo in a pattern that gets interpreted as an unused binding, look for unit struct/variant of the same type as the binding: ``` error: unused variable: `Non` --> $DIR/binding-typo-2.rs:36:9 | LL | Non => {} | ^^^ | help: if this is intentional, prefix it with an underscore | LL | _Non => {} | + help: you might have meant to pattern match on the similarly named variant `None` | LL - Non => {} LL + std::prelude::v1::None => {} | ```
