  "message": "Introduce ABSL_OPTION_INLINE_HW_ACCEL_STRATEGY in absl/base/options.h\nto provide a centralized policy for hardware-accelerated\nimplementations in headers.\n\nThis option addresses ODR violations that occur when Abseil headers\nuse compile-time feature detection (such as __SSE4_2__) in inline\nfunctions. If translation units are compiled with inconsistent CPU\narchitecture flags (e.g., -march\u003dnative vs -march\u003dgeneric) and linked\ntogether, they may disagree on the implementation of these inline\nfunctions. This can lead to crashes or silent data corruption in\nhashing.\n\nThe new option provides three levels of control:\n- 0: Portable. Forces software-only implementations in headers,\n  guaranteeing ABI safety across mixed translation units.\n- 1: Required. Forces hardware-accelerated implementations in\n  headers. The build will fail if the required instructions are not\n  enabled in the compiler environment.\n- 2: Auto-detect. Selects the best available implementation based on\n  compiler flags, but can\u0027t guarantee safety if translation units are\n  compiled with inconsistent flags.\n\nPiperOrigin-RevId: 896569507\nChange-Id: Ifcbc1f3980883feeaa4f05f845ce32310ca7d533\n",
