| at all. These intrinsics only make sense without a body, and can be declared as a `#[rustc_intrinsic]`. | ||
| The body is never used, as calls to the intrinsic do not exist anymore after MIR analyses. | ||
| The body is never used as the lowering pass implements support for all backends, so we never have to | ||

@rust-lang/rust-analyzer I guess this PR will fail to land since RA has a copy of this file for the hover_feature test. How can I adjust the test to not require such a hard-to-maintain full copy?

Is there a feature that won't really ever change maybe that we can just swap to?

Ah well, replacing the hover test with
#[test]
fn hover_feature() {
let (analysis, position) = fixture::position(r#"#![feature(intrinsics$0)]"#);
analysis
.hover(
&HoverConfig { links_in_hover: true, ..HOVER_BASE_CONFIG },
FileRange { file_id: position.file_id, range: TextRange::empty(position.offset) },
)
.unwrap()
.unwrap();
}should suffice

As someone who has ran into tests relying on "surely this unstable feature will never change" about a dozen times over the years, and each time had to do a frustrating search for what this test actually cared about and what was entirely incidental reliance on a feature -- I'd prefer if we didn't go down that route. Why does the test need to compare the full string for equality? There's no reason for that that I can think of.
If absolutely necessary we could probably have a dedicated feature that exists solely for the purpose of testing.

Ah, that's great, thanks a lot. :)
