You should think of "RISC" as a "set of reduced instructions",
and not a "reduced set of instructions". Even IBM's original
RISC had a fairly large *number* of instructions, but fancier
do-all instructions were removed in favor of instructions which
did less, and thus could always complete in fewer CPU cycles.
