 186         Static variables which are used to set the ISA extensions. You can
 187         use -march (or ELF build attributes) and -misa-spec to set them,
 188         respectively.
 189         (ext_version_hash): The hash table used to handle the extensions
 190         with versions.

 209         2p2 version.  For m-ext, we do not set the version by -march and ELF arch
 210         attribute, so set the default 2p0 to it.  For zicsr, it is not defined in
 211         ISA spec 2p2, so set 0p0 to it.

 240         (enum reg_class): We now get the CSR address from csr_extra_hash rather
 241         than reg_names_hash.  Therefore, move RCLASS_CSR behind RCLASS_MAX.
