Abstract
An apparatus is described having an out-of-order instruction execution pipeline. The out-of-order execution pipeline has a first circuit and a second circuit. The first circuit is to hold a pointer to physical storage space where information is kept that cannot yet be confirmed as being free of potential dependencies on the information. The second circuit is to hold the pointer if the pointer existed in the first circuit when a non speculative region of program code ended and upon retirement of a following speculative overwriter instruction originally coded to overwrite the information.
