1 @c This file contains the entry for the -w/--debug-dump (readelf) and
2 @c -W/--dwarf (objdump) option that is common to both readelf and objdump.
4 Displays the contents of the DWARF debug sections in the file, if any
5 are present. Compressed debug sections are automatically decompressed
6 (temporarily) before they are displayed. If one or more of the
7 optional letters or words follows the switch then only those type(s)
8 of data will be dumped. The letters and words refer to the following

15 Displays the contents of the @samp{.debug_abbrev} section.
19 Displays the contents of the @samp{.debug_addr} section.
23 Displays the contents of the @samp{.debug_cu_index} and/or
24 @samp{.debug_tu_index} sections.

36 Displays the contents of the @samp{.gdb_index} and/or
37 @samp{.debug_names} sections.
41 Displays the contents of the @samp{.debug_info} section. Note: the
42 output from this option can also be restricted by the use of the
43 @option{--dwarf-depth} and @option{--dwarf-start} options.
47 Displays the contents of the @samp{.gnu_debuglink},
48 @samp{.gnu_debugaltlink} and @samp{.debug_sup} sections, if any of
49 them are present. Also displays any links to separate dwarf object
50 files (dwo), if they are specified by the DW_AT_GNU_dwo_name or
51 DW_AT_dwo_name attributes in the @samp{.debug_info} section.
55 Display the contents of any selected debug sections that are found in
56 linked, separate debug info file(s). This can result in multiple
57 versions of the same debug section being displayed if it exists in
60 In addition, when displaying DWARF attributes, if a form is found that
61 references the separate debug info file, then the referenced contents
62 will also be displayed.
64 Note - in some distributions this option is enabled by default. It
65 can be disabled via the @option{N} debug option. The default can be
66 chosen when configuring the binutils via the
67 @option{--enable-follow-debug-links=yes} or
68 @option{--enable-follow-debug-links=no} options. If these are not
69 used then the default is to enable the following of debug links.
72 @itemx =no-follow-links
73 Disables the following of links to separate debug info files.
77 Displays the contents of the @samp{.debug_line} section in a raw
82 Displays the interpreted contents of the @samp{.debug_line} section.
86 Displays the contents of the @samp{.debug_macro} and/or
87 @samp{.debug_macinfo} sections.
91 Displays the contents of the @samp{.debug_loc} and/or
92 @samp{.debug_loclists} sections.
96 Displays the contents of the @samp{.debug_str_offsets} section.

101 @samp{.debug_gnu_pubnames} sections.
105 Displays the contents of the @samp{.debug_aranges} section.
109 Displays the contents of the @samp{.debug_ranges} and/or
110 @samp{.debug_rnglists} sections.
114 Displays the contents of the @samp{.debug_str}, @samp{.debug_line_str}
115 and/or @samp{.debug_str_offsets} sections.
119 Displays the contents of the @samp{.debug_pubtypes} and/or

123 @itemx =trace_aranges
124 Displays the contents of the @samp{.trace_aranges} section.
128 Displays the contents of the @samp{.trace_abbrev} section.
132 Displays the contents of the @samp{.trace_info} section.
136 Note: displaying the contents of @samp{.debug_static_funcs},
137 @samp{.debug_static_vars} and @samp{debug_weaknames} sections is not
140 @item --dwarf-depth=@var{n}
141 Limit the dump of the @code{.debug_info} section to @var{n} children.
142 This is only useful with @option{--debug-dump=info}. The default is
143 to print all DIEs; the special value 0 for @var{n} will also have this
146 With a non-zero value for @var{n}, DIEs at or deeper than @var{n}
147 levels will not be printed. The range for @var{n} is zero-based.
149 @item --dwarf-start=@var{n}
150 Print only DIEs beginning with the DIE numbered @var{n}. This is only
151 useful with @option{--debug-dump=info}.
153 If specified, this option will suppress printing of any header
154 information and all DIEs before the DIE numbered @var{n}. Only
155 siblings and children of the specified DIE will be printed.
157 This can be used in conjunction with @option{--dwarf-depth}.
