![]() Uplift `clippy::cmp_nan` lint This PR aims at uplifting the `clippy::cmp_nan` lint into rustc. ## `invalid_nan_comparisons` ~~(deny-by-default)~~ (warn-by-default) The `invalid_nan_comparisons` lint checks comparison with `f32::NAN` or `f64::NAN` as one of the operand. ### Example ```rust,compile_fail let a = 2.3f32; if a == f32::NAN {} ``` ### Explanation NaN does not compare meaningfully to anything – not even itself – so those comparisons are always false. ----- Mostly followed the instructions for uplifting a clippy lint described here: https://github.com/rust-lang/rust/pull/99696#pullrequestreview-1134072751 `@rustbot` label: +I-lang-nominated r? compiler |
