Inline asm named label is not supported

[Kotodian]

It happened on this page

A no_std rust library

// in `elk/src/process.rs`

#[inline(never)]
unsafe fn jmp(entry_point: *const u8, stack_contents: *const u64, qword_count: usize) {
    asm!(
        // allocate (qword_count * 8) bytes
        "mov {tmp}, {qword_count}",
        "sal {tmp}, 3",
        "sub rsp, {tmp}",
         # 👇 here
        ".l1:",
        // start at i = (n-1)
        "sub {qword_count}, 1",
        // copy qwords to the stack
        "mov {tmp}, QWORD PTR [{stack_contents}+{qword_count}*8]",
        "mov QWORD PTR [rsp+{qword_count}*8], {tmp}",
        // loop if i isn't zero, break otherwise
        "test {qword_count}, {qword_count}",
        "jnz .l1",

        "jmp {entry_point}",

        entry_point = in(reg) entry_point,
        stack_contents = in(reg) stack_contents,
        qword_count = in(reg) qword_count,
        tmp = out(reg) _,
    )
}

Here's what the issue is

Compilation Failure in rust 1.78.0-nightly

I'm not familiar with asm code, do you know how to fix it? Thx
