Zusammenfassung:An apparatus and method of operating a data processing apparatus are provided. The data processing circuitry is responsive to a hint instruction to then assert at least one performance modifying control signal, when subsequently generating control signals for other data processing instructions. This causes the data processing functional hardware which performs the data processing operations defined by the data processing instructions to operate in a modified manner, although the data processing results produced do not change in dependence on whether the at least one performance modifying control signal is asserted.
