Subject: [PULL 11/33] linux-user/i386: Use explicit little-endian LD/ST API
Date: Tue, 15 Oct 2024 12:44:20 -0300 [thread overview]
Message-ID: <20241015154443.71763-12-philmd@linaro.org> (raw)
In-Reply-To: <20241015154443.71763-1-philmd@linaro.org>
The x86 architecture uses little endianness. Directly use
the little-endian LD/ST API.
