Abstract
A method includes suppressing execution of an operation portion of a load-operation instruction in a processor responsive to an invalid status of a load portion of load-operation instruction. A processor includes an instruction pipeline including an execution unit operable to execute instructions and a scheduler unit. The scheduler unit includes a scheduler queue and is operable to store a load-operation in the scheduler queue. The load-operation instruction includes a load portion and an operation portion. The scheduler unit schedules the load portion for execution in the execution unit, marks the operation portion in the scheduler queue as eligible for execution responsive to scheduling the load portion, receives an indication of an invalid status of the load portion, and suppresses execution of the operation portion responsive to the indication of the invalid status.
