Subject: [PULL 48/58] hw/mips: Evaluate TARGET_BIG_ENDIAN at compile time
Date: Fri, 25 Apr 2025 17:28:32 +0200 [thread overview]
Message-ID: <20250425152843.69638-49-philmd@linaro.org> (raw)
In-Reply-To: <20250425152843.69638-1-philmd@linaro.org>
Rather than evaluating TARGET_BIG_ENDIAN at preprocessing
time via #ifdef'ry, do it in C at compile time
Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org>
