    Description

      We can reduce the required linking time by setting flags which removes need for running wasm-emscripten-finalize. See https://emscripten.org/docs/optimizing/Optimizing-Code.html#link-times

      Flags which should be changed from the current Qt default include:

      • ASSERTIONS to 1 
      • WASM_BIGINT to 1

      Asyncify requires wasm-emscripten-finalize, so changing the flags above has no effect for asyncify-enabled builds.
