    Description

      Currently, webassembly has support for 64 bit memory - but in Emscripten, it is still a WIP and experimental. It currently lacks features such as exceptions (longjmp), threads and dynamic linking

      Emscripten has some support with -S MEMORY64

      This is to keep track and occasionally test Emscripten and Qt WebAssembly can support wasm64.
