Rollup merge of #127853 - folkertdev:naked-function-error-messages, r=bjorn3
`#[naked]`: report incompatible attributes tracking issue: https://github.com/rust-lang/rust/issues/90957 this is a re-implementation of https://github.com/rust-lang/rust/pull/93809 by ``@bstrie`` which was closed 2 years ago due to inactivity. This PR takes some of the final comments into account, specifically providing a little more context in error messages, and using an allow list to determine which attributes are compatible with `#[naked]`. Notable attributes that are incompatible with `#[naked]` are: * `#[inline]` * `#[track_caller]` * ~~`#[target_feature]`~~ (this is now allowed, see PR discussion) * `#[test]`, `#[ignore]`, `#[should_panic]` These attributes just directly conflict with what `#[naked]` should do. Naked functions are still important for systems programming, embedded, and operating systems, so I'd like to move them forward.
