The described embodiments include a processor that determines instructions that can be issued based on unresolved data dependencies. In an issue unit in the processor, the processor keeps a record of each instruction that is directly or indirectly dependent on a base instruction. Upon determining that the base instruction has been deferred, the processor monitors instructions that are being issued from an issue queue to an execution unit for execution. Upon determining that an instruction from the record has reached a head of the issue queue, the processor immediately issues the instruction from the issue queue.
