Abstract
A system may include a dispatch unit, a scheduler, and an execution core. The dispatch unit may be configured to modify a load operation to include a register-to-register move operation in response to an indication that a speculative result of the load operation is linked to a data value identified by a first tag. The scheduler may be coupled to the dispatch unit and configured to issue the register-to-register move operation in response to availability of the data value. The execution core may be configured to execute the register-to-register move operation by outputting the data value and a tag indicating that the data value is the result of the load operation.
