@cindex ELF dynamic symbol table information
Displays the entries in dynamic symbol table section of the file, if it

symbol hash tables in the file's dynamic section, rather than the
symbol table sections.

Displays the contents of the indicated section as a hexadecimal bytes.

command to @command{ar}, but without using the BFD library. @xref{ar}.

-@itemx --debug-dump[=rawline,=decodedline,=info,=abbrev,=pubnames,=aranges,=macro,=frames,=frames-interp,=str,=loc,=Ranges,=pubtypes,=trace_info,=trace_abbrev,=trace_aranges,=gdb_index]
-Displays the contents of the debug sections in the file, if any are
-present. If one of the optional letters or words follows the switch
-then only data found in those specific sections will be dumped.
-
-Note that there is no single letter option to display the content of
-trace sections or .gdb_index.
-
-Note: the @option{=decodedline} option will display the interpreted
-contents of a .debug_line section whereas the @option{=rawline} option
-dumps the contents in a raw format.
-
-Note: the @option{=frames-interp} option will display the interpreted
-contents of a .debug_frame section whereas the @option{=frames} option
-dumps the contents in a raw format.
-
-Note: the output from the @option{=info} option can also be affected
-by the options @option{--dwarf-depth} and @option{--dwarf-start}.
-
-@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}.
