//! This is a regression test for <https://github.com/rust-lang/rust/issues/137366>, ensuring

//! that we can use the `neon` target feature on ARM32 targets in rustdoc despite there
|
|
//! being a "forbidden" feature of the same name for aarch64, and rustdoc merging the
|
|
//! target features of all targets.
