+
+       * elf-bfd.h (bfd_section_is_ctf): New inline function.
+       * elf.c (special_sections_c): Add ".ctf".
+       (assign_file_positions_for_non_load_sections): Note that
+       compressed debugging sections etc are not assigned here.  Treat
+       CTF sections like SEC_ELF_COMPRESS sections when is_linker_output:
+       sh_offset -1.
+       (assign_file_positions_except_relocs): Likewise.
+       (find_section_in_list): Note that debugging and CTF sections, as
+       well as reloc sections, are assigned later.
+       (_bfd_elf_assign_file_positions_for_non_load): CTF sections get
+       their size and contents updated.
+       (_bfd_elf_set_section_contents): Skip CTF sections: unlike
+       compressed sections, they have no uncompressed content to copy at
+       this stage.
+       * elflink.c (elf_link_swap_symbols_out): Call the examine_strtab
+       callback right before the strtab is written out.
+       (bfd_elf_final_link): Don't cache the section contents of CTF
+       sections: they are not populated yet.  Call the emit_ctf callback
+       right at the end, after all the symbols and strings are flushed
+       out.
