摘要：
Embodiments of the invention relate to dynamically routing instructions to execution units based on detected errors in the execution units. An aspect of the invention includes a computer system including a processor having an instruction issue unit and a plurality of execution units. The processor is configured to detect an error in a first execution unit among the plurality of execution units and adjust instruction dispatch rules of the instruction issue unit based on detecting the error in the first execution unit to restrict access to the first execution unit while leaving un-restricted access to the remaining execution units of the plurality of execution units.
