Abstract
A register window spill technique for an retirement window having an entry size less than a number of spill instructions used in a spill condition is provided. The technique uses modified spill instructions that allow the retirement window to retire a portion of the spill instructions without having to determine whether a remaining portion of the spill instructions will execute without exceptions.
