A computer system, a processor in a computer and a computer-implemented method executable on a computer processor involve dividing a set of computer instructions arranged in a sequential program order into a plurality of instruction sequences. Instructions within each sequence are arranged according to the program order. An increment value is assigned to a preceding instruction in each sequence. The increment value is equal to a difference between a program order value of a subsequent instruction in the sequence and a program order value of the preceding instruction. The processor calculates the program order value of each subsequent instruction based on the program order value and the increment value of a corresponding preceding instruction in the same sequence.
