   2
   3         * config/tc-riscv.c (explicit_csr): New static boolean.
   4         Used to indicate CSR are explictly used.
   5         (riscv_ip): Set explicit_csr to TRUE if any CSR is used.
   6         (riscv_write_out_attrs): If we already have set elf priv
   7         attributes, then generate them.  Otherwise, don't generate
   8         them when no CSR are used.
   9         * testsuite/gas/riscv/attribute-01.d: Remove the priv attributes.
  10         * testsuite/gas/riscv/attribute-02.d: Likewise.

  21         * testsuite/gas/riscv/attribute-11.d: New testcase.  The CSR is
  22         used, so we should output the ELF priv attributes.
  23         * testsuite/gas/riscv/attribute-12.d: New testcase.  The CSR is
  24         used, so output the priv attributes according to the -mpriv-spec.
  25         * testsuite/gas/riscv/attribute-13.d: New testcase.  The CSR isn't
  26         used, so ignore the -mpriv-spec setting.

 225         Static variables which are used to set the ISA extensions. You can
 226         use -march (or ELF build attributes) and -misa-spec to set them,
 227         respectively.

 229         with versions.

 279         (enum reg_class): We now get the CSR address from csr_extra_hash rather
