Subject: [PATCH 01/19] target/arm: Fix field extract from MVFR[0-2]
Date: Fri, 14 Feb 2020 10:15:29 -0800 [thread overview]
Message-ID: <20200214181547.21408-2-richard.henderson@linaro.org> (raw)
In-Reply-To: <20200214181547.21408-1-richard.henderson@linaro.org>
These registers are 32-bits wide. Cut and paste used FIELD_EX64
instead of the more proper FIELD_EX32. In practice all this did
was use an unnecessary 64-bit operation, producing correct results.
