Arm AArch64 Adds Memcpy() Instructions
Thus begins the slide from RISC to (what POWER/PowerPC ended up calling) FISC. It's not about reducing the instruction set, it's about designing a fast instruction set with easy-to-generate, generalizable instructions. Even more than PowerPC (which generally added interesting but less primitive register-to-register ops), this is going straight to richer memory-to-memory ops.
