Subject: [PATCH 51/65] target/riscv: Add widening integer reduction instructions for XTheadVector
Date: Fri, 12 Apr 2024 15:37:21 +0800	[thread overview]
Message-ID: <20240412073735.76413-52-eric.huang@linux.alibaba.com> (raw)
In-Reply-To: <20240412073735.76413-1-eric.huang@linux.alibaba.com>

The instructions have the same function as RVV1.0. Overall there are only
general differences between XTheadVector and RVV1.0.
