Subject: [PATCH v1 01/11] target/arm: Add isar_feature_{aa32, aa64, aa64_sve}_bf16
Date: Fri, 16 Apr 2021 16:59:18 -0700	[thread overview]
Message-ID: <20210416235928.1631788-2-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210416235928.1631788-1-richard.henderson@linaro.org>

Note that the SVE BFLOAT16 support does not require SVE2,
it is an independent extension.
