Subject: [PULL 27/27] target/arm: Use correct FPST for VCMLA, VCADD on fp16
Date: Mon, 24 Aug 2020 10:48:11 +0100	[thread overview]
Message-ID: <20200824094811.15439-28-peter.maydell@linaro.org> (raw)
In-Reply-To: <20200824094811.15439-1-peter.maydell@linaro.org>

When we implemented the VCMLA and VCADD insns we put in the
code to handle fp16, but left it using the standard fp status
flags. Correct them to use FPST_STD_F16 for fp16 operations.
