This is true. A multi-tier JIT-compiler requires writable execute memory and the ability to flush icache. Loading segments dynamically is nice and covers a lot of the ground, but it won't be a magic solution to dynamic languages like JavaScript. Modern WASM emulators already implement a full compiler, linker and JIT-compiler in one, almost starting to look like v8. I'm not sure if adding in-guest JIT support is going in the right direction. |
