Add support to readelf and objdump for following links to separate debug information files.
Hi Guys,
I am applying the rather large patch attached to this email to enhance
the readelf and objdump programs so that they now have the ability to
follow links to separate debug info files. (As requested by PR
15152). So for example whereas before we had this output:
$ readelf -wi main.exe
Contents of the .debug_info section:
[...]
<15> DW_AT_comp_dir : (alt indirect string, offset: 0x30c)
[...]
With the new option enabled we get:
$ readelf -wiK main.exe
main.exe: Found separate debug info file: dwz.debug
Contents of the .debug_info section (loaded from main.exe):
[...]
<15> DW_AT_comp_dir : (alt indirect string, offset: 0x30c) /home/nickc/Downloads/dwzm
[...]
The link following feature also means that we can get two lots of
output if the same section exists in both the main file and the
separate debug info file:
$ readelf -wiK main.exe
main.exe: Found separate debug info file: dwz.debug
Contents of the .debug_info section (loaded from main.exe):
[...]
Contents of the .debug_info section (loaded from dwz.debug):
[...]
The patch also adds the ability to display the contents of debuglink
sections:
$ readelf -wk main.exe
Contents of the .gnu_debugaltlink section:
Separate debug info file: dwz.debug
Build-ID (0x14 bytes):
c4 a8 89 8d 64 cf 70 8a 35 68 21 f2 ed 24 45 3e 18 7a 7a 93
Naturally there are long versions of these options (=follow-links and
=links). The documentation has been updated as well, and since both
readelf and objdump use the same set of debug display options, I have
moved the text into a separate file. There are also a couple of new
binutils tests to exercise the new behaviour.
There are a couple of missing features in the current patch however,
although I do intend to address them in follow up submissions:
Firstly the code does not check the build-id inside separate debug
info files when it is searching for a file specified by a
.gnu_debugaltlink section. It just assumes that if the file is there,
then it contains the information being sought.
Secondly I have not checked the DWARF-5 version of these link
features, so there will probably be code to add there.
Thirdly I have only implemented link following for the
DW_FORM_GNU_strp_alt format. Other alternate formats (eg
DW_FORM_GNU_ref_alt) have yet to be implemented.
Lastly, whilst implementing this feature I found it necessary to move
some of the global variables used by readelf (eg section_headers) into
a structure that can be passed around. I have moved all of the global
variables that were necessary to get the patch working, but I need to
complete the operation and move the remaining, file-specific variables
(eg dynamic_strings).
Cheers
Nick

@samp{.debug_names} sections.
|
||||
|
||||
@item i
|

@itemx =info
|

Displays the contents of the @samp{.debug_info} section. Note: the

@item K

@itemx =follow-links
|
||||
Display the contents of any selected debug sections that are found in
|
||||
a linked, separate debug info file. This can result in multiple
|
||||
versions of the same debug section being displayed if both the main
|
||||
file and the separate debug info file contain sections with the same
|
||||
name.
|
||||
|
||||
When displaying other debug information, if a link is encountered to
|
||||
a separate debug info file, then attempt to follow the link and
|
||||
display the referenced contents.
|
||||
|
||||
@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
|

@samp{.debug_loclists} sections.
|
||||
|
||||
@item p
|
||||
@itemx =pubnames
|

|
||||
@samp{.debug_gnu_pubnames} sections.
|

@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}.
