Emit a diagnostic when lint attributes (allow, deny, warn, forbid) are used without arguments. Previously, these attributes were accepted silently if malformed, which could lead to confusion or ignored lints. This ensures users are informed of the expected form: #[allow(lint_name)]. Fixes Rust-GCC#4358 gcc/rust/ChangeLog: * util/rust-attributes.cc (check_lint_attribute): New helper. (AttributeChecker::visit): Call helper for lint attributes on functions. gcc/testsuite/ChangeLog: * rust/compile/allow-malformed.rs: New test. Signed-off-by: Jayant Chauhan <[email protected]>

Argh, forgot I just merged a PR that kinda breaks most tests. You need to prefix your test with those two lines: We're now injecting it by default in every crate that does not have the |

Please check back later.
The lint attributes (allow, deny, warn, forbid) require arguments specifying which lints to affect. Using them without arguments (e.g. #[allow]) is invalid. This patch adds validation to reject empty lint attributes.
Fixes #4225
