Abstract

See full text

Embodiments relate to instruction filtering. An aspect includes a computer-implemented method for instruction filtering. The method includes detecting, by a processor, a tracked instruction in an instruction stream, and storing an instruction address of the tracked instruction in a tracking array based on detecting and executing the tracked instruction. The method also includes accessing the tracking array based on an address of instruction data of a subsequently fetched instruction to locate the instruction address of the tracked instruction in the tracking array as an indication of the tracked instruction. The method further includes marking, by the processor, instruction text of the subsequently fetched instruction to indicate that the subsequently fetched instruction is a previously executed tracked instruction based on the indication of the tracked instruction from the tracking array. The method additionally includes preventing an action of a tracked instruction logic block based on detecting the marked instruction text.
