 ### Debugging type layouts
 
-The internal attribute `#[rustc_layout]` can be used to dump the [`Layout`] of
-the type it is attached to.
+The internal attribute `#[rustc_dump_layout(...)]` can be used to dump the
+[`Layout`] of the type it is attached to.
 For example:
 
 ```rust
 #![feature(rustc_attrs)]
 
-#[rustc_layout(debug)]
+#[rustc_dump_layout(debug)]
 type T<'a> = &'a u32;
 ```
 
 Will emit the following:
