160b1a618a PR22443, Global buffer overflow in _bfd_elf_get_symbol_version_string
Symbols like *ABS* defined in bfd/section.c:global_syms are not
elf_symbol_type.  They can appear on relocs and perhaps other places
in an ELF bfd, so a number of places in nm.c and objdump.c are wrong
to cast an asymbol based on the bfd being ELF.  I think we lose
nothing by excluding all section symbols, not just the global_syms.

dda8d76d0d 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

003ca0fd22 Refactor disassembler selection
Nowadays, opcodes/disassemble.c:disassembler selects the proper
disassembler according to ABFD only.  However, it actually
selects disassemblers according to arch, mach, endianess, and
abfd.  This patch adds them to the parameters of disassembler,
so that its caller can still select disassemblers in case that
abfd is NULL (a typical case in GDB).

There isn't any functionality change.

1737c64030 objdump: Better objdump section headers in wide mode
When displaying the section headers table using objdump (-h), the column
containing the section header name is currently fixed at 13 characters.
A section name that is longer than 13 characters will overflow the
column causing the table to become miss-aligned.

In this commit I change the behaviour so that _in wide mode_ (-w -h) the
section name column is dynamically resized to fit the longest section
name we plan to display.  In wide mode the column still retains a
minimum width of 13 characters.

In non-wide more the behaviour is completely unchanged.

While I was changing the dump_headers function I have unified the two
printf lines that handled the different address widths into a single
printf, the address width is now passed into printf using the '*' field
width format character.

binutils/ChangeLog:

	* objdump.c (dump_section_header): Extract max section name length
	from data parameter, use this when formatting output.
	(find_longest_section_name): New function.
	(dump_headers): Calculate longest section name when in wide mode,
	reformat to unify printing of header line.

ld/ChangeLog:

	* testsuite/ld-elf/eh-frame-hdr.d: Update expected results.

	last_file is true, do not call bfd_close at the end of the

f4943d8253 Don't always build coffgen.o
Removes a bunch of unused functions from libbfd when building ELF or
AOUT.  Split off the bits we need externally when not building a COFF
target into coff-bfd.c and coff-bfd.h.
