Subject: [PULL 16/33] hw/xtensa/xtfpga: Remove TARGET_BIG_ENDIAN #ifdef'ry
Date: Tue, 15 Oct 2024 12:44:25 -0300 [thread overview]
Message-ID: <20241015154443.71763-17-philmd@linaro.org> (raw)
In-Reply-To: <20241015154443.71763-1-philmd@linaro.org>
Move code evaluation from preprocessor to compiler so
both if() ladders are processed. Mostly style change.
Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org>
