I’m facing an issue with Unsigned numbers in kotlin/js

Kotlin common code:

var x: ULong? = 1_000_000.toULong()
...
val s = "x: ${x}"

generated JS code for the toString of x

function toString_1(o) {
    var tmp;
    if (o == null) {
      tmp = 'null';
    } else if (isArrayish(o)) {
      tmp = '[...]';
    } else if (!(typeof o.toString === 'function')) {
      tmp = anyToString(o);
    } else {
      // Inline function 'kotlin.js.unsafeCast' call
      tmp = o.toString();
    }
    return tmp;
  }
//---
  function ULong__toString_impl_f9au7k($this) {
    // Inline function 'kotlin.ulongToString' call
    var value = _ULong___get_data__impl__fggpzb($this);
    return ulongToString(value, 10);
  }
//---
function ulongToString(value, base) {
    if (value.compareTo_kvbqny_k$(new Long(0, 0)) >= 0)
      return toString_2(value, base);

---

And in runtime

compareTo_kvbqny_k$ is undefined

kotlin v2.0.0, js IR

Any ideas?

not seeing the issue, https://pl.kotl.in/EhOvw5Mo0

[ephemient]

do you have a mcve? something else is going on because compareTo doesn't look like it's on this codepath

Can't reproduce even with 2.0.0

I didn’t create an MCVE, i wanted to first see if anyone knows anything as i’ve seen that there are some issues around unsigned stuff in kotlin/js
