  "message": "Use write-intent destination prefetches in temporal CRC32C copy mode.\n\nRead-only prefetches on cold destination cache lines fetch lines in shared state, stalling temporal stores on shared-to-modified ownership upgrades when retiring full-cache-line writes.\n\nIn `ExtendWithPclmul` on multi-PCLMUL x86 targets in temporal copy mode, prefetch the initial cache lines of each stream before the main loop and switch main-loop destination prefetches to `PrefetchToLocalCacheForWrite` (`prefetchw`) with a 5-cache-line horizon, clamping the final stream\u0027s prefetches to the end of the buffer so trailing bytes are prefetched without issuing write-prefetches past `dst + length`.\n\nPiperOrigin-RevId: 1009821683\n",
