//!
//! The actual definitions were copied from rustc's `compiler/rustc_feature/src/builtin_attrs.rs`.
//!
//! It was last synchronized with upstream commit 2225ee1b62ff089917434aefd9b2bf509cfa087f.
//!
//! The macros were adjusted to only expand to the attribute name, since that is all we need to do
//! name resolution, and `BUILTIN_ATTRIBUTES` is almost entirely unchanged from the original, to
//! ease updating.
