[PATCH] target/riscv: FCSR doesn't contain vxrm and vxsat


From: LIU Zhiwei
Subject: [PATCH] target/riscv: FCSR doesn't contain vxrm and vxsat
Date: Tue, 30 Jan 2024 19:09:45 +0800

vxrm and vxsat have been moved into a special register vcsr since
RVV v1.0. So remove them from FCSR for vector 1.0.
