Subject: [PATCH 58/65] target/riscv: Add vector iota instruction for XTheadVector
Date: Fri, 12 Apr 2024 15:37:28 +0800 [thread overview]
Message-ID: <20240412073735.76413-59-eric.huang@linux.alibaba.com> (raw)
In-Reply-To: <20240412073735.76413-1-eric.huang@linux.alibaba.com>
The instruction has the same function as RVV1.0. Overall there are only
general differences between XTheadVector and RVV1.0.
