Subject: [PATCH 02/20] target/arm: Split out gen_gvec_fn_zz
Date: Fri, 14 Aug 2020 18:31:27 -0700 [thread overview]
Message-ID: <20200815013145.539409-3-richard.henderson@linaro.org> (raw)
In-Reply-To: <20200815013145.539409-1-richard.henderson@linaro.org>
Model the new function on gen_gvec_fn2 in translate-a64.c, but
indicating which kind of register and in which order. Since there
is only one user of do_vector2_z, fold it into do_mov_z.
