Abstract
A processor and method for tracking instruction execution within a processor are described. The processor includes at least one execution unit that executes instructions and an instruction status indicator that dynamically indicates a status of an instruction during processing. The instruction status indicator has at least a first state to which the instruction status indicator is set in order to indicate that execution of the instruction is stalled. In one embodiment, the processor further includes a reason code indicator associated with the instruction status indicator that specifies an event occurrence that caused the indicated instruction status. In another embodiment, the processor further includes a history buffer that indicates the number of processor cycles that the status indicated by the instruction status indicator has remained unchanged.
