There was a problem hiding this comment.
Since this lint wasn't gated, it should be removed "properly" and marked as register_removed over in compiler/rustc_lint/src/lib.rs.
(Thanks to @compiler-errors for confirming this.)

This looks right in terms of what we asked for as a lang matter. With the requested change to remove the lint properly, the implementation looks reasonable to me, so please have a look and feel free to r? compiler-errors @rustbot author |

tracking issue: #138997
Because the details of the rust abi are unstable, and a naked function must match its stated ABI, this feature gate keeps naked functions with a rustic abi ("Rust", "rust-cold", "rust-call" and "rust-intrinsic") unstable.
