Subject: [PATCH 04/19] target/arm: Set MVFR0.FPSP for ARMv5 cpus
Date: Fri, 14 Feb 2020 10:15:32 -0800 [thread overview]
Message-ID: <20200214181547.21408-5-richard.henderson@linaro.org> (raw)
In-Reply-To: <20200214181547.21408-1-richard.henderson@linaro.org>
We are going to convert FEATURE tests to ISAR tests,
so FPSP needs to be set for these cpus, like we have
already for FPDP.
