Abstract:
A computer implemented method, apparatus, and computer program product for executing instructions. A determination is made as to whether a processor executing a plurality of instructions is in an instrumentation mode. The processor has a normal set of resources and an alternate set of resources in which the alternate set of resources is associated with the instrumentation mode. When a determination is made that the processor is in the instrumentation mode, the processor executes instrumentation instructions in the plurality of instructions using the alternate set of resources and executes all other instructions in the plurality of instructions using the normal set of resources.
