Subject: [PATCH] target/riscv: FCSR doesn't contain vxrm and vxsat
Date: Tue, 30 Jan 2024 19:09:45 +0800 [thread overview]
Message-ID: <20240130110945.486-1-zhiwei_liu@linux.alibaba.com> (raw)
vxrm and vxsat have been moved into a special register vcsr since
RVV v1.0. So remove them from FCSR for vector 1.0.
