You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: issue-1002.rs
    path of file: ./repos/rust-gpu/tests/ui/lang/asm
    
    the code of the file until where you have to start completion: // Tests that we don't allow returning from `asm!` (which would always be UB).
// build-fail

use core::arch::asm;
use spirv
    
fn asm_return_value(x: u32) -> u32 {
    unsafe {
        asm!(
            "OpReturnValue {x}",
            x = in(reg) x,
            options(noreturn),
        );
    }
}
