Abstract
Aspects of the invention include tracking dependencies between instructions in an issue queue. The tracking includes, for each instruction in the issue queue, identifying whether the instruction is dependent on each of a threshold number of instructions added to the issue queue prior to the instruction. The tracking also includes identifying whether the instruction is dependent on one or more other instructions in a group of instructions in the issue queue that were added to the issue queue prior to the instruction and that are not included in the threshold number of instructions that are tracked individually. A dependency between the instruction and the one or more other instructions in the group of instructions is tracked using a single summary bit that is set to indicate that a dependency exists between the instruction and the group of instructions. Instructions are issued from the issue queue based at least in part on the tracking.
