+ * 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.
