Subject: [PATCH 16/16] util/bitmap: Replace HOST_BIG_ENDIAN #ifdef with runtime if() check
Date: Fri, 10 Oct 2025 15:42:25 +0200 [thread overview]
Message-ID: <20251010134226.72221-17-philmd@linaro.org> (raw)
In-Reply-To: <20251010134226.72221-1-philmd@linaro.org>
Replace compile-time #ifdef with a runtime check to ensure all code
paths are built and tested. This reduces build-time configuration
complexity and improves maintainability.
No functional change intended.
