Subject: [PATCH v4 51/78] target/arm: Split out formats for 3 vectors + 1 index
Date: Tue,  9 Mar 2021 08:20:14 -0800	[thread overview]
Message-ID: <20210309162041.23124-52-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210309162041.23124-1-richard.henderson@linaro.org>

Used by FMLA and DOT, but will shortly be used more.
Split FMLA from FMLS to avoid an extra sub field;
similarly for SDOT from UDOT.

Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
