This instruction loads a 128 bit wide value into a register and marks the corresponding cache block as "least recently used" i.e. as the prime candidate for eviction upon a need to evict a block from its cache set. To appropriately use that instruction in the context of the above example, the data elements referenced by the loop would have to be loaded using this instruction.
This instruction loads a 128-bit wide value into a register and marks the corresponding cache block as "least recently used" (LRU), making it a prime candidate for eviction when needed. To effectively use this instruction in the given scenario, the data elements referenced by the loop would need to be loaded using this instruction.
