I was a little worried this would get MIR inlined, but it seems like that doesn't happen right now at least... https://rust.godbolt.org/z/jvs7K3W9f

fn callee_neon(a: i32, b: i32) -> i32 {
a + b
}

#[no_mangle]
#[target_feature(enable = "neon")]
pub fn caller_neon(x: i32, y: i32) -> i32 {
// CHECK-LABEL: define noundef i32 @caller_neon(
// CHECK: [[R:%[0-9A-Za-z_.]+]] = add
callee_neon(x, y)
}
