- masklinn 12y agoAny JIT-based system requires executable writable memory. This includes the JVM, LuaJIT, Pypy, HHVM and all modern browsers.
- m_eiman 12y agoIt'd be quite possible for a JIT to have the memory first writable but not executable when creating the code, then the other way around when running it. No need to be both at the same time.
