Abstract

A non-limiting example of a computer-implemented method for file register writes using pointers includes, responsive to a dispatch instruction, storing, at a location in a history buffer, an instruction tag and first data associated with the instruction tag. The method further includes storing a pointer in an issue queue. The pointer points to the location in the history buffer. The method further includes performing a write back of second data using the pointer stored in the issue queue. The write back writes the second data into the location of the history buffer associated with the pointer.
