Very cool! This all would not be possible with your wasm forks -- they are the saving grace here.
Nice that you got it running.
GC also needs some investigation (or malloc), as I keep get spurious OOM errors. Could be because dmd is one hell of a memory hog, but who knows.
So far I haven't hit those when running druntime/phobos tests, but they could be caused by pointers being hidden from GC because they sit on the wasm stack/registers.
The only way to solve that would be to (somehow) have LDC put them on the shadow stack whenever they aren't. I know of some experiments where they did this with a boehm style GC on emscripten. Maybe I need to look more into how other languages (like go) handle this.
