  "message": "[nsan] Emit calls to optimized functions (#98900)\n\nAs previously noted in nsan.cpp we can implement\r\noptimized variants of `__nsan_copy_values` and\r\n`__nsan_set_value_unknown` if a memory operation\r\nsize is known.\r\nNow the instrumentation creates calls to optimized functions if there is\r\n4, 8 or 16-byte memory operation like\r\n`memset(X, value, 4/8/16)` or `memcpy(dst, src, 4/8/16)`\r\nnsan.cpp provides definitions of the optimized functions.",
