Code

#[target_feature(enable = "popcnt")]
pub fn add_simd(x: i32, y: i32) -> i32 {
    x + y
}

Reproduction Steps

rustdoc +nightly ./mcve.rs

Expected Outcome

Function isn't marked as unsafe in index page:

Actual Output

Function is marked as ⚠ to indicate it's unsafe.

But on the function's own page, it's correct.
