Abstract
Data processing circuitry comprises out-of-order instruction execution circuitry to execute program instructions in an instruction execution order; a data store, to store information on a set of instructions for which execution has been initiated, the data store providing ordering information indicating the relative position of each instruction in the set of instructions with respect to a program code order; commit circuitry to commit the results of instructions executed by the instruction execution circuitry; one or more cumulative status registers configured to be set in response to a respective condition generated by execution of an instruction and then to remain set until an unset instruction is executed; and an identifier store, to store for at least those of the one or more cumulative status registers which are not currently set, an identifier of an instruction which is earliest in the program code order in the set of instructions and which generated a condition to set that cumulative status register.
