Add support for decoding the DW_MACRO_define_strx and DW_MACRO_undef_strx operands...

@c This file contains the entry for the -w/--debug-dump (readelf) and
@c  -W/--dwarf (objdump) option that is common to both readelf and objdump.

Displays the contents of the DWARF debug sections in the file, if any
are present.  Compressed debug sections are automatically decompressed
(temporarily) before they are displayed.  If one or more of the
optional letters or words follows the switch then only those type(s)
of data will be dumped.  The letters and words refer to the following
information:

@c Please Keep This Table Alpha Sorted.
@table @code
@item a
@itemx =abbrev
Displays the contents of the @samp{.debug_abbrev} section.

@item A
@itemx =addr
Displays the contents of the @samp{.debug_addr} section.

@item c
@itemx =cu_index
Displays the contents of the @samp{.debug_cu_index} and/or
@samp{.debug_tu_index} sections.

@item f
@itemx =frames
Display the raw contents of a @samp{.debug_frame} section.

@item F
@item =frame-interp
Display the interpreted contents of a @samp{.debug_frame} section.

@item g
@itemx =gdb_index
Displays the contents of the @samp{.gdb_index} and/or
@samp{.debug_names} sections.

@item i
@itemx =info
Displays the contents of the @samp{.debug_info} section.  Note: the
output from this option can also be restricted by the use of the 
@option{--dwarf-depth} and @option{--dwarf-start} options.

@item k
@itemx =links
Displays the contents of the @samp{.gnu_debuglink} and/or
@samp{.gnu_debugaltlink} sections.  Also displays any links to
separate dwarf object files (dwo), if they are specified by the 
DW_AT_GNU_dwo_name or DW_AT_dwo_name attributes in the
@samp{.debug_info} section.

@item K
@itemx =follow-links
Display the contents of any selected debug sections that are found in
linked, separate debug info file(s).  This can result in multiple
versions of the same debug section being displayed if it exists in
more than one file.

In addition, when displaying DWARF attributes, if a form is found that
references the separate debug info file, then the referenced contents
will also be displayed.

@item l
@itemx =rawline
Displays the contents of the @samp{.debug_line} section in a raw
format.

@item L
@item =decodedline
Displays the interpreted contents of the @samp{.debug_line} section.

@item m
@itemx =macro
Displays the contents of the @samp{.debug_macro} and/or
@samp{.debug_macinfo} sections.

@item o
@itemx =loc
Displays the contents of the @samp{.debug_loc} and/or
@samp{.debug_loclists} sections.

@item O
@itemx =str-offsets
Displays the contents of the @samp{.debug_str_offsets} section.

@item p
@itemx =pubnames
Displays the contents of the @samp{.debug_pubnames} and/or
@samp{.debug_gnu_pubnames} sections.

@item r
@itemx =aranges
Displays the contents of the @samp{.debug_aranges} section.

@item R
@itemx =Ranges
Displays the contents of the @samp{.debug_ranges} and/or
@samp{.debug_rnglists} sections.

@item s
@itemx =str
Displays the contents of the @samp{.debug_str}, @samp{.debug_line_str}
and/or @samp{.debug_str_offsets} sections.

@item t
@itemx =pubtype
Displays the contents of the @samp{.debug_pubtypes} and/or
@samp{.debug_gnu_pubtypes} sections.

@item T
@itemx =trace_aranges
Displays the contents of the @samp{.trace_aranges} section.

@item u
@itemx =trace_abbrev
Displays the contents of the @samp{.trace_abbrev} section.

@item U
@itemx =trace_info
Displays the contents of the @samp{.trace_info} section.

@end table

Note: displaying the contents of @samp{.debug_static_funcs},
@samp{.debug_static_vars} and @samp{debug_weaknames} sections is not
currently supported.

@item --dwarf-depth=@var{n}
Limit the dump of the @code{.debug_info} section to @var{n} children.
This is only useful with @option{--debug-dump=info}.  The default is
to print all DIEs; the special value 0 for @var{n} will also have this
effect.

With a non-zero value for @var{n}, DIEs at or deeper than @var{n}
levels will not be printed.  The range for @var{n} is zero-based.

@item --dwarf-start=@var{n}
Print only DIEs beginning with the DIE numbered @var{n}.  This is only
useful with @option{--debug-dump=info}.

If specified, this option will suppress printing of any header
information and all DIEs before the DIE numbered @var{n}.  Only
siblings and children of the specified DIE will be printed.

This can be used in conjunction with @option{--dwarf-depth}.
