 * `intrinsics` - Allows use of the "rust-intrinsics" ABI. Compiler intrinsics
                  are inherently unstable and no promise about them is made.
 
-* `int_uint` - Allows the use of the `int` and `uint` types, which are deprecated.
-               Use `isize` and `usize` instead.

 * `lang_items` - Allows use of the `#[lang]` attribute. Like `intrinsics`,
