Abstract:
A method for link stack misprediction resolution using a rename structure for tracking the link stack processing, in order to quickly resolve link stack corruption from mispredicted function returns. The method comprises establishing a set of physical data structures forming a common pool and an operation control table. Maintaining, within the common pool, a plurality of entries for a plurality of speculative instructions and a plurality of non-speculative instructions. And determining one speculative instruction to be a bad prediction speculative entry, identifying related entries to form a collection, and discarding the collection.
