Subject: [PATCH 33/65] target/riscv: Add widening saturating scaled multiply-add instructions for XTheadVector
Date: Fri, 12 Apr 2024 15:37:03 +0800 [thread overview]
Message-ID: <20240412073735.76413-34-eric.huang@linux.alibaba.com> (raw)
In-Reply-To: <20240412073735.76413-1-eric.huang@linux.alibaba.com>
There are no instructions similar to these instructions in RVV1.0. So we
implement them by writing their own functions instead of copying code from
RVV1.0.
