Subject: [PATCH 09/76] target/arm: Drop new_tmp_a64_zero
Date: Fri, 24 Feb 2023 23:13:20 -1000	[thread overview]
Message-ID: <20230225091427.1817156-10-richard.henderson@linaro.org> (raw)
In-Reply-To: <20230225091427.1817156-1-richard.henderson@linaro.org>

Only the use within cpu_reg requires a writable temp,
so inline new_tmp_a64_zero there.  All other uses are
fine with a constant temp, so use tcg_constant_i64(0).
