they fit in with C++ since we all use Ahead-of-Time compilers? In this talk I'll tell you about C++ AoT compiler, JiTs for dynamic language, JiTs for binary translation, and dive back 20, 30, 40, 50, 60 systems: pages mapped X at some point in time are modified.AoT AoT Ahead-of-Time compilation Is AoT the opposite of JiT? C and C++ are pretty much AoT these days: compile code to a target machine, then run run it. X mapping never changes.? Interpreter Is an interpreter a JiT, or AoT? What if it modifies its bytecode? A CPU executes machine code… an interpreter executes bytecode… That’s the same thing
