  18         Used to indicate CSR are explictly used.
  19         (riscv_ip): Set explicit_csr to TRUE if any CSR is used.
  20         (riscv_write_out_attrs): If we already have set elf priv
  21         attributes, then generate them.  Otherwise, don't generate
  22         them when no CSR are used.
