Subject: [PATCH 09/19] target/arm: Replace ARM_FEATURE_VFP3 checks with fp{sp, dp}_v3
Date: Fri, 14 Feb 2020 10:15:37 -0800	[thread overview]
Message-ID: <20200214181547.21408-10-richard.henderson@linaro.org> (raw)
In-Reply-To: <20200214181547.21408-1-richard.henderson@linaro.org>

Sort this check to the start of a trans_* function.
Merge this with any existing test for fpdp_v2.
