[PATCH v4 01/22] target/riscv: Fix trap cause for RV32 HS-mode CSR access from RV64 HS-mode |
Date: |
Tue, 26 Oct 2021 12:12:06 +0530 |
We should be returning illegal instruction trap when RV64 HS-mode tries
to access RV32 HS-mode CSR.
Fixes: d6f20dacea51 ("target/riscv: Fix 32-bit HS mode access permissions")
