out of a normal single-threaded program possible (provided that dependencies are checked, etc.). It opens up for more analysis and therefore also for reordering of code sequences in order to dynamically optimize mapping and scheduling of uops onto machine resources (such as ALUs, load/store units, etc.). As this happens on the uop-level, sub-operations of different machine (macro) instructions may often intermix in a particular uop-sequence, forming partially reordered machine instructions as a direct
