That's right, this function decided whether the section will be striped out by default, if it has set `SEC_DEBUGGING' in BFD section flags then section is removed by the default. For `.ctf' this flag is not set because in `_bfd_elf_make_section_from_shdr' when BFD sections are building it uses the section's name: ".debug", ".gnu.debuglto_.debug_", ".gnu.linkonce.wi.", ".zdebug", "lines", ".stab", etc, to set `SEC_DEBUGGING' flag. > binutils/objcopy.c.
