Vmifynow compiles Lua into register instructions executed by a generated interpreter, giving Prometheus v0.3 a real VM. The previous control-flow flattening implementation is available asCff.Opcode IDs and operand layouts are randomized. The interpreter uses a balanced dispatcher, with optimizations for assignments, calls, and register cleanup. Medium applies Cff to surrounding helpers while excluding the VM and prototype tables.
