Subject: [PULL 23/33] target/arm: Enable FEAT_MOPS insns in user-mode emulation
Date: Thu,  2 Nov 2023 17:38:25 +0000	[thread overview]
Message-ID: <20231102173835.609985-24-peter.maydell@linaro.org> (raw)
In-Reply-To: <20231102173835.609985-1-peter.maydell@linaro.org>

In user-mode emulation, we need to set the SCTLR_EL1.MSCEn
bit to avoid all the FEAT_MOPS insns UNDEFing.
