46cbf38dc3 binutils: Add new GNU format mode to size utility 
The size tool currently defaults to berkeley format output.  However,
this output format has a weird quirk, read-only data is counted
against the text sections, not the data sections.

The code offers no real explanation for why this is, but I'm reluctant
to change it for two reasons, first, I'm assuming it probably makes
sense in some case that I'm not thinking of (maybe a target where
sections are not marked executable, and so there's no distinction
between read-only data and code), and second, the code has been this
way for at least 20 years, I worry that changing things now might
cause more confusion than it solves.

This commit then introduces a new output format for the size tool,
this new format displays the results in a similar manor to the
berkeley format, but counts read-only data in the data column, and
only executable sections are counted in the text column.

Given that this is a brand new output format I've gone ahead and
simplified things a little, while the berkeley format displays the
total twice, once in decimal and once in hex, the new display format
just displays the total in decimal.  Of course, there's still the
'--radix' option which can be used to display all the results in
hexadecimal or octal.

I've called the new format 'gnu', so '--format=gnu' or '-G' are used
to access it.

	(enum output_format): New enum.

af03af8f55 Synchronize libiberty with gcc and add --no-recruse-limit option to tools that support name demangling. 
This patch addresses the multitude of bug reports about resource exhaustion
in libiberty's name demangling code.  It adds a limit to the amount of
recursion that is allowed, before an error is triggered.  It also adds a
new demangling option to disable this limit.  (The limit is enabled by
default).

a05a5b64cf Fix use of "command line X" in binutils doc 
Binutils documentation uses a mix of spelling for the compound word
"command-line X". According to [1]:

"Sometimes compound words are written separately (nail polish),
sometimes with a hyphen (short-sighted) and sometimes as one word
(eyelashes). Often new compounds are written as two separate words and,
as they become more familiar, they are either connected with a hyphen
(-) or made into one word."

I think command-line X is common enough in our industry that the two
workds command and line should be connected. Since command-line is more
common than commandline, I propose to update binutils documentation to
consistently use "command-line" when this is used as an adjective to a
noun (eg. command-line argument, command-line switch, command-line
option and command-line flag). I've left occurences of "the command
line" as is. I've also left gdb, sim and readline alone and have only
touched public documentation (texi and NEWS files).

7d02540ab7 Allow non-fatal errors to be emitted and for disassembly notes be placed on AArch64 
This patch adds a new platform option "notes" that can be used to indicate if
disassembly notes should be placed in the disassembly as comments.

These notes can contain information about a failing constraint such as reading
from a write-only register.  The disassembly will not be blocked because of this
but -M notes will emit a comment saying that the operation is not allowed.

For assembly this patch adds a new non-fatal status for errors.  This is
essentially a warning.  The reason for not creating an actual warning type is
that this causes the interaction between the ordering of warnings and errors to
be problematic.  Currently the error buffer is almost always filled because of
the way operands are matched during assembly. An earlier template may have put
an error there that would only be displayed if no other template matches or
generates a higher priority error.  But by definition a warning is lower
priority than a warning, so the error (which is incorrect if another template
matched) will supersede the warning.  By treating warnings as errors and only
later relaxing the severity this relationship keeps working and the existing
reporting infrastructure can be re-used.

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

25499ac7ee MIPS16e2: Add MIPS16e2 ASE support 
Add MIPS16e2 ASE support as per the architecture specification[1],
including in particular:

1. A new ELF ASE flag to mark MIPS16e2 binaries.

2. MIPS16e2 instruction assembly support, including a relaxation update
   to use LUI rather than an LI/SLL instruction pair for loading the
   high part of 32-bit addresses.

3. MIPS16e2 instruction disassembly support, including updated rules for
   extended forms of instructions that are now subdecoded and therefore
   do not alias to the original MIPS16 ISA revision instructions even
   for encodings that are not valid in the MIPS16e2 instruction set.

Add `-mmips16e2' and `-mno-mips16e2' GAS command-line options and their
corresponding `mips16e2' and `no-mips16e2' settings for the `.set' and
`.module' pseudo-ops.  Control the availability of the MT ASE subset of
the MIPS16e2 instruction set with a combination of these controls and
the preexisting MT ASE controls.

Parts of this change by Matthew Fortune and Andrew Bennett.

a91e1603af Support ELF SHF_GNU_MBIND and PT_GNU_MBIND_XXX 
Mark an ALLOC section, which should be placed in special memory area,
with SHF_GNU_MBIND.  Its sh_info field indicates the special memory
type.  GNU_MBIND section names start with ".mbind" so that they are
placed as orphan sections by linker.  All input GNU_MBIND sections
with the same sh_type, sh_flags and sh_info are placed in one output
GNU_MBIND section.  In executable and shared object, create a
GNU_MBIND segment for each GNU_MBIND section and its segment type is
PT_GNU_MBIND_LO plus the sh_info value.  Each GNU_MBIND segment is
aligned at page boundary.

The assembler syntax:

    .section .mbind.foo,"adx",%progbits
                          ^             0: Special memory type.
                          |
                         'd' for SHF_GNU_MBIND.

    .section .mbind.foo,"adx",%progbits,0x1
                          ^             1: Special memory type.
                          |
                         'd' for SHF_GNU_MBIND.

    .section .mbind.bar,"adG",%progbits,.foo_group,comdat,0x2
                          ^                               2: Special memory type.
                          |

d3e5f6c8f1 objcopy/strip: Add option --remove-relocations=SECTIONPATTERN 
The objcopy and strip tools make use of the bfd library to manipulate
the state of the input file (to produce an output file).  Within the
input file (for ELF at least), relocations are held within a section,
and so, if the user wanted to remove the relocations, but keep the
section to which the relocations would have been applied, it is tempting
to think that specifying the name of a relocation section to objcopy's
--remove-section option might do what you want, for example:

   objcopy --remove-section=.rela.text input.elf output.elf

However, this does not work.  The reason is that when the input file is
loaded, relocations are not managed as sections, but are, instead,
loaded as data associated with the section to which the relocations
would be applied.  In our example above the relocations in '.rela.text'
are held as data on the section '.text' once 'input.elf' is loaded.

One task that objcopy and strip do is copy the relocations from the
input file to the output file if the section is also being copied from
the input file to the output file.

This commit adds a new command line option for objcopy and strip,
--remove-relocations, which can be used to remove the relocations, while
keeping the section that the relocations would have been applied to, for
example:

    objcopy --remove-relocations=.text input.elf output.elf

in this case the section '.text' will appear in both 'input.elf' and
'output.elf', but any relocations in 'input.elf' that apply to '.text'
will not be present in 'output.elf'.

I have also added a special case to the handling of --remove-section
that spots if a user tries to remove a relocation section (currently
this is done by spotting the '.rela.' or '.rel.' prefix) and forwards
the request to --remove-relocations.

As with --remove-section and --only-section the --remove-relocations
option supports the '!' prefix on the section-patterns it takes to allow
for sections to be specifically not matched.

There are tests for all the new functionality.

e511c9b19f objcopy/strip: Allow section patterns starting with '!'. 
For symbol matching, prefixing a pattern with '!' will indicate a
non-matching pattern, however, this is not the case for section
patterns.  As a result it is not possible to say "apply this action to
all sections except ...".

With this commit the objcopy and strip tools now support '!' prefix for
section patterns, so we can say:

  objcopy --remove-section="*" --remove-section="!.text*"

Which will remove all sections, except those matching the pattern
'.text*'.

e6cc316af9 Enable 64-bit archives in ar and ranlib 
Since existing ld and gold support the 64-bit (MIPS) ELF archives, we
can use the 64-bit (MIPS) ELF archives as 64-bit archives.  Since the
plugin target is used to create archive in plugin-enabled ar, we need
a way to enable 64-bit archives in the plugin target.  This patch adds
--enable-64-bit-archive to bfd to force 64-bit archives in ar and
ranlib.  Since both 64-bit MIPS and s390 ELF targets currently use
64-bit archives, 64-bit archives are enabled by default for them.
64-bit archive is generated automatically if the archive is too big.

Tested on Linux/x86 and Linux/x86-64 with existing ld and gold.

b8871f357f Properly implement STT_COMMON 
The BFD configure option, --enable-elf-stt-common, can't be to used to
verify STT_COMMON implementation with the normal binutils build.  Instead,
this patch removes it from BFD.  It adds --elf-stt-common=[no|yes] to ELF
assembler/objcopy and adds -z common/-z nocommon to ld.

A configure option, --enable-elf-stt-common, is added to gas to specify
whether ELF assembler should generate common symbols with the STT_COMMON
type by default.

Since BSF_KEEP_G is never used, it is renamed to BSF_ELF_COMMON for ELF
common symbols.

acf1419f9c objcopy: Add --update-section option. 
New option for objcopy --update-section allows the contents of a section
to be updated while maintaining the section flags, and, for ELF files,
the section to segment mapping.

New test uses --dump-section and --update-section to check that a
section can be made larger and smaller with an update.

binutils/ChangeLog:

	* objcopy.c (update_sections): New list.
	(command_line_switch): Add OPTION_UPDATE_SECTION.
	(copy_options): Add update-section.
	(copy_usage): Document new option.
	(is_update_section): New function.
	(is_strip_section_1): Add check for attempt to update and remove
	the same section.
	(copy_object): Update size and content of requested sections.
	(skip_section): Don't copy for updated sections.
	(copy_main): Handle --update-section.
	* doc/binutils.texi (objcopy): Add description of --update-section
	option.
	* NEWS: Mention --update-section option.
