Allow (but don't require) `#[unsafe(naked)]` so that `compiler-builtins` can upgrade to it tracking issue: https://github.com/rust-lang/rust/issues/138997 Per https://github.com/rust-lang/rust/pull/134213#issuecomment-2755984503, we want to make the `#[naked]` attribute an unsafe attribute. Making that change runs into a cyclic dependency with `compiler-builtins` which uses `#[naked]`, where `rustc` needs an updated `compiler-builtins` and vice versa. So based on https://github.com/rust-lang/rust/pull/139753 and [#t-compiler/help > updating `compiler-builtins` and `rustc`](https://rust-lang.zulipchat.com/#narrow/channel/182449-t-compiler.2Fhelp/topic/updating.20.60compiler-builtins.60.20and.20.60rustc.60), this PR allows, but does not require `#[unsafe(naked)]`, and makes that change for some of the tests to check that both `#[naked]` and `#[unsafe(naked)]` are accepted. Then we can upgrade and synchronize `compiler-builtins`, and then make `#[naked]` (without `unsafe`) invalid. r? `@traviscross` (or someone from t-compiler if you're faster and this look allright) |

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
