Any plan for EVAL_CTORS supporting in multi-threaded app?

[junyuecao]

There is an option for emcc to speed up the initializaton but it seems not supported for multi-threaded app.
https://emscripten.org/docs/optimizing/Optimizing-Code.html#eval-ctors

Is threre any plan to support in multi-threaded app?

The error is

error: library_pthread.js: library_pthread.js:23: #error "EVAL_CTORS is not compatible with pthreads yet (passive segments)"

which is correct, I think. The ctor-evaller would need to support passive segments, that is, segments that it can't see their absolute location at compile time, somehow.

I am not aware of current work on this, but it would be good to add eventually, and there has been other work on the ctor-evaller recently (e.g. support for WasmGC).

I think if we fix #12682 then I think this would be possible.
