--- Comment #3 from Jan Palus <jpalus at fastmail dot com> ---
If I understand it correctly in binutils primary criteria for removing section
is whether it is marked with SEC_DEBUGGING flag:
https://sourceware.org/git/?p=binutils-gdb.git;a=blob;f=binutils/objcopy.c;h=d20aaef9f4f2e2a910bd7bf666dab6e3c158fc1b;hb=HEAD#l1366
and the flag for ELF seems to be set here:
https://sourceware.org/git/?p=binutils-gdb.git;a=blob;f=bfd/elf.c;h=81825b748d75f2b68a6cca1c54b126df53c36dc2;hb=HEAD#l1093
if (startswith (name, ".debug")
|| startswith (name, ".gnu.debuglto_.debug_")
|| startswith (name, ".gnu.linkonce.wi.")
|| startswith (name, ".zdebug"))
flags |= SEC_DEBUGGING | SEC_ELF_OCTETS;
else if (startswith (name, GNU_BUILD_ATTRS_SECTION_NAME)
|| startswith (name, ".note.gnu"))
{
flags |= SEC_ELF_OCTETS;
opb = 1;
}
else if (startswith (name, ".line")
|| startswith (name, ".stab")
|| strcmp (name, ".gdb_index") == 0)
flags |= SEC_DEBUGGING;
