Micro-ops aren't RISC instructions, too complex. For instance, vfmadd132ps instruction loads 32 bytes from memory, multiplies by 8 FP32 numbers, adds to another

Micro-ops aren't RISC instructions, too complex. For instance, vfmadd132ps instruction loads 32 bytes from memory, multiplies by 8 FP32 numbers, adds to another 8 numbers - yet on most processors that instruction decodes into a single micro-op.
