Subject: [PATCH 56/57] target/arm: Tidy SQDMULH, SQRDMULH (vector)
Date: Sun,  5 May 2024 18:04:02 -0700	[thread overview]
Message-ID: <20240506010403.6204-57-richard.henderson@linaro.org> (raw)
In-Reply-To: <20240506010403.6204-1-richard.henderson@linaro.org>

We already have a gvec helper for the operations, but we aren't
using it on the aa32 neon side.  Create a unified expander for
use by both aa32 and aa64 translators.

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