• The removal of the #[target_feature(enable = "sse2,avx,avx2")] attribute from the binary_dot_product_simd function can lead to undefined behavior if the required target features are not available. Please ensure the required features are enabled.

#[target_feature(enable = "sse2,avx,avx2")]

• The function name native_dot_produce should be corrected to native_dot_product.

let diff = neg_dot_product(&lhs, &rhs) + native_dot_produce(&lhs, &rhs);
