Condition Code Source. > CCO : (?) instruction name Condition Code Operation These 3 are used to implement lazy flag evaluation. Most x86 instructions set the condition code flags, but only a relatively small subset of instructions actually use these flags. Calculating the flags at every operation would be very slow. Instead qemu just remembers the destination, one source operand and the instruction class of a flag setting operation, then lazily evaluates the flags as needed.
