Subject: [PULL 09/32] target/arm: Split out aa32_max_features
Date: Mon, 9 May 2022 12:58:25 +0100 [thread overview]
Message-ID: <20220509115848.3521805-10-peter.maydell@linaro.org> (raw)
In-Reply-To: <20220509115848.3521805-1-peter.maydell@linaro.org>
From: Richard Henderson <richard.henderson@linaro.org>
Share the code to set AArch32 max features so that we no
longer have code drift between qemu{-system,}-{arm,aarch64}.
