It was a weekend hack that I abandoned because I grew tired of figuring out EVM details.
I’m afraid it’s a big mess. At the time, I thought it might be fun to try interleaving the stack and heap, as I had a hunch it would lead to fewer dirty pages for wasm VM to track. I regret the complexity caused by this premature optimization.
