A base portion extends radially from the shaft adjacent the second end of the shaft. IP-relative addresses may be computed in a manner similar to relative branch targets, then compressed and stored in one or more micro-operation entries of a micro-operation storage line to be reconstructed later according to an IP address associated with the respective micro-operation storage line in which their compressed counterpart was stored.
