+       * elfxx-riscv.h (riscv_parse_subset_t): Add new callback function
+       get_default_version.  It is used to find the default version for
+       the specific extension.
+       * elfxx-riscv.c (riscv_parsing_subset_version): Remove the parameters
+       default_major_version and default_minor_version.  Add new bfd_boolean
+       parameter *use_default_version.  Set it to TRUE if we need to call
+       the callback rps->get_default_version to find the default version.
+       (riscv_parse_std_ext): Call rps->get_default_version if we fail to find
+       the default version in riscv_parsing_subset_version, and then call
+       riscv_add_subset to add the subset into subset list.
+       (riscv_parse_prefixed_ext): Likewise.
+       (riscv_std_z_ext_strtab): Support Zicsr extensions.
+       * elfnn-riscv.c (riscv_merge_std_ext): Use strcasecmp to compare the
+       strings rather than characters.
+       riscv_merge_arch_attr_info): The callback function get_default_version
+       is only needed for assembler, so set it to NULL int the linker.
+       * elfxx-riscv.c (riscv_estimate_digit): Remove the static.
+       * elfxx-riscv.h: Updated.
