Subject: [Qemu-devel] [PATCH 1/5] hw/net/eepro100.c: Don't use cpu_to_*w() and *_to_cpup()
Date: Thu, 16 Jun 2016 18:17:22 +0100 [thread overview]
Message-ID: <1466097446-981-2-git-send-email-peter.maydell@linaro.org> (raw)
In-Reply-To: <1466097446-981-1-git-send-email-peter.maydell@linaro.org>
Don't use cpu_to_*w() and *_to_cpup() to do byte-swapped loads
and stores; instead use ld*_p() and st*_p() which correctly handle
misaligned accesses.
