  "message": "Disable VPCLMUL for Non-temporal copies.\n\nThe VPCLMUL functionality relies on inline assembly, and LLVM\u0027s new x86-fence-nontemporal-stores pass inserts an sfence before every inline assembly block when non-temporal stores are issued before them, which dramatically hurts non-temporal crc_memcpy performance here.\n\nSo, we introduce an \"active pclmul stream type\" here that allows platforms with vpclmul streams to fall back to the regular pclmul implementation when doing non-temporal copies.\n\nPiperOrigin-RevId: 1017480997\n",
