elf.c special_sections: missing .debug_<dwarf> sections?

[dje at google dot com]

Hi.

While debugging binutils/14662 I found this:

static const struct bfd_elf_special_section special_sections_d[] =
{
  { STRING_COMMA_LEN (".data"),         -2, SHT_PROGBITS, SHF_ALLOC + SHF_WRITE },
  { STRING_COMMA_LEN (".data1"),         0, SHT_PROGBITS, SHF_ALLOC + SHF_WRITE },
  { STRING_COMMA_LEN (".debug"),         0, SHT_PROGBITS, 0 },
  { STRING_COMMA_LEN (".debug_line"),    0, SHT_PROGBITS, 0 },
  { STRING_COMMA_LEN (".debug_info"),    0, SHT_PROGBITS, 0 },
  { STRING_COMMA_LEN (".debug_abbrev"),  0, SHT_PROGBITS, 0 },
  { STRING_COMMA_LEN (".debug_aranges"), 0, SHT_PROGBITS, 0 },
  { STRING_COMMA_LEN (".dynamic"),       0, SHT_DYNAMIC,  SHF_ALLOC },
  { STRING_COMMA_LEN (".dynstr"),        0, SHT_STRTAB,   SHF_ALLOC },
  { STRING_COMMA_LEN (".dynsym"),        0, SHT_DYNSYM,   SHF_ALLOC },
  { NULL,                      0,        0, 0,            0 }
};

There's a whole lot more DWARF sections than just those ones.

Perhaps this stuff is only used for assembler-written code,
and thus the absence of the other dwarf sections never manifests
itself in practice.
In that case it would at least be nice to add a comment explaining
why it's ok to elide the other sections (e.g., .debug_types).

What's the story here?
