--- Comment #3 from Mark Wielaard <mark at gcc dot gnu.org> ---
So gcc/dwarf2out.c creates it as:

#define DEBUG_STR_SECTION_FLAGS                                 \
  (HAVE_GAS_SHF_MERGE && flag_merge_debug_strings               \
   ? SECTION_DEBUG | SECTION_MERGE | SECTION_STRINGS | 1        \
   : SECTION_DEBUG)

        debug_line_str_section =3D get_section (DEBUG_LINE_STR_SECTION,
                                              DEBUG_STR_SECTION_FLAGS, NULL=
);

And gas/dwarf2dbg.c sets the flags as:

      bfd_set_section_flags (line_str_seg,
                             SEC_READONLY | SEC_DEBUGGING | SEC_OCTETS
                             | SEC_MERGE | SEC_STRINGS);

I hope that results in the same section type/flags set. But you should prob=
ably
check because MIPS has some special cases.=
