Subject: [Qemu-devel] [PATCH 10/10] ARM: Implement VCVT to 16 bit integer using new softfloat routines
Date: Mon, 6 Dec 2010 17:00:11 +0000 [thread overview]
Message-ID: <1291654811-29863-11-git-send-email-peter.maydell@linaro.org> (raw)
In-Reply-To: <1291654811-29863-1-git-send-email-peter.maydell@linaro.org>
Use the softfloat conversion routines for conversion to 16 bit
integers, because just casting to a 16 bit type truncates the
value rather than saturating it at 16-bit MAXINT/MININT.
