Subject: [PATCH v4 06/18] target/arm: Use MAKE_64BIT_MASK to compute indexmask
Date: Tue,  1 Mar 2022 11:59:46 -1000	[thread overview]
Message-ID: <20220301215958.157011-7-richard.henderson@linaro.org> (raw)
In-Reply-To: <20220301215958.157011-1-richard.henderson@linaro.org>

The macro is a bit more readable than the inlined computation.
