Subject: [Qemu-devel] [PATCH 4/4] target-arm: Make Neon helper routines use correct FP status
Date: Mon,  4 Apr 2011 11:46:35 +0100	[thread overview]
Message-ID: <1301913995-2506-5-git-send-email-peter.maydell@linaro.org> (raw)
In-Reply-To: <1301913995-2506-1-git-send-email-peter.maydell@linaro.org>

Make the Neon helper routines use the correct FP status from
the CPUEnv rather than using a dummy static one. This means
they will correctly handle denormals and NaNs and will set
FPSCR exception bits properly.
