code snippet to reproduce:

fn rdtscp() -> u64 {
    let hi: u64;
    let lo: u64;
    unsafe {
        std::arch::asm!(
            "rdtscp",
            out("rdx") hi,
            out("rax") lo,
            out("rcx") _,
            options(nomem, nostack, preserves_flags)
        );
    }
    (hi << 32) | lo
}

rust-analyzer shows an error on the line out("rcx") _:
