   7
   8         * config/tc-riscv.c (explicit_csr): New static boolean.
   9         Used to indicate CSR are explictly used.
  10         (riscv_ip): Set explicit_csr to TRUE if any CSR is used.
  11         (riscv_write_out_attrs): If we already have set elf priv
  12         attributes, then generate them.  Otherwise, don't generate
  13         them when no CSR are used.
  14         * testsuite/gas/riscv/attribute-01.d: Remove the priv attributes.

  26         * testsuite/gas/riscv/attribute-11.d: New testcase.  The CSR is
  27         used, so we should output the ELF priv attributes.
  28         * testsuite/gas/riscv/attribute-12.d: New testcase.  The CSR is
  29         used, so output the priv attributes according to the -mpriv-spec.
  30         * testsuite/gas/riscv/attribute-13.d: New testcase.  The CSR isn't
  31         used, so ignore the -mpriv-spec setting.

 232         respectively.
