Embodiments of an apparatus, method, and system provide for no-operation
instruction ("NOP") folding such that information regarding the presence
of a NOP instruction in the instruction stream is folded into a buffer
entry for another instruction. Information regarding a target NOP
instruction is thus maintained in a buffer entry associated with an
instruction other than the target NOP instruction. For at least one
embodiment, NOP information is folded into entries of a re-order buffer.
