Abstract
Aspects of the invention include detecting, in an out-of-order (OoO) processor, that all instructions in a first group of in-flight instructions have a status of finished. The first group of in-flight instructions is the oldest group in an entry of a global completion table (GCT). It is determined that the entry in the GCT is a merged entry that is associated with both the first group of in-flight instructions and a second group of in-flight instructions dispatched immediately subsequent to the first group of in-flight instructions. The first group of in-flight instructions and the second group of in-flight instructions are completed in a single processor cycle. The completing is based at least in part on detecting that all instructions in the first group of in-flight instructions have a status of finished. The completing includes requesting release of resources utilized by both the first and second groups of in-flight instructions.
