NativeAOT will not generate a RUC warning if its inside an attribute #72805

Description

Description

NativeAOT will bypass warning generation for Requires if it's embedded in a custom attribute. The usage of the custom attribute should generate a warning

Reproduction Steps

publicclassRequiresOnAttributeCtorAttribute:Attribute{[RequiresUnreferencedCode("Message from attribute's ctor.")]publicRequiresOnAttributeCtorAttribute(){}}[RequiresUnreferencedCode("Message from attribute's type.")]publicclassRequiresOnAttributeTypeAttribute:Attribute{}// Not generated warnings:// [ExpectedWarning ("IL2026", "Message from attribute's ctor.")]// [ExpectedWarning ("IL2026", "Message from attribute's type.")][RequiresOnAttributeCtor][RequiresOnAttributeType]publicvoidMethod(){}

Expected behavior

Warnings are generated when accessing a custom attribute with members annotated with Requires

Actual behavior

Warnings are not generated when accessing a custom attribute with members annotated with Requires
