Subject: [Qemu-devel] [PATCH v2 08/29] tcg: Promote tcg_out_{dup, dupi}_vec to backend interface
Date: Tue, 30 Apr 2019 22:05:15 -0700 [thread overview]
Message-ID: <20190501050536.15580-9-richard.henderson@linaro.org> (raw)
In-Reply-To: <20190501050536.15580-1-richard.henderson@linaro.org>
The i386 backend already has these functions, and the aarch64
backend could easily split out one. Nothing is done with these
functions yet, but this will aid register allocation of
INDEX_op_dup_vec in a later patch.
Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
