METHOD AND APPARATUS FOR PROVIDING A GENERAL PURPOSE STACK

A method and apparatus for providing a stack in a processor-based system. In one embodiment, the apparatus comprises a memory for storing instruction sequences by which the processor-based system is processed; and a processor coupled to the memory that executes the stored instruction sequences, where the processor has a plurality of registers. The stored instruction sequences cause the processor to: (a) determine a condition of occupancy of the plurality of registers; and (b) rearrange the contents of each of the plurality of registers in accordance with a predetermined order.
