6f156d7a4a Add support for v3 binary annotation notes.
I am checking in the attached patch which updates the binutils
  support for version 3 binary annotation notes.  (Version 3 adds
  an end address to the ranges covered by the notes, so that it
  is possible to detect gaps in the coverage).

  This patch also stops the note merging feature of objcopy from
  executing if the notes have relocations against them.  This makes the
  code simpler, and prevents the problems with architectures which have
  unusual relocation management issues.

2d054e6bfd Fix stripping relocs in a file with mergeable notes.
A recent Fedora bug (1520805) exposed a problem with objcopy's reloc
  copying code, when a binary also contains mergeable notes.  The note
  merging code would delete some relocs, but then the reloc copying code
  would try to put them back again, which did not work.

  So I am checking in the patch below to fix the problem.  The patch
  also tweaks one of the binutils note merging tests so that it is
  skipped for the Sparc64 target, since this has funky relocs.

binutils	* objcopy.c (copy_relocations_in_section): Use the orelocations
	field of the input section, if it has been initialised.
	* testsuite/binutils-all/note-2-64.d: Skip test on Sparc64.

b4f5b984e5 binutils: remove sparc64/mips64 workaround in objcopy build notes merge code
This patch removes a workaround recently installed in objcopy that
avoided removing duplicated notes in targets for which the number of
internal relocations may be bigger than the number of external

workaround is no longer necessary.

4bc26c6959 bfd: Rename Chunk and S3Forced
The direct references in objcopy kind of look like a hack to me, so
I'm calling these symbols internal too.  Certainly they aren't named
and documented as a public BFD symbol today anyway.

So ... give these bfd-internal symbols with external linkage a _bfd_
prefix to avoid collisions in the global symbol namespace.

While at it, give them names that more closely match the corresponding
option name that toggles them.

Also while at it, fix a few related comment typos.

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*'.

9cc0123fea MIPS objcopy --rename-section fix
Some MIPS targets use a named section symbol rather than a symbol with
no name as is used with most ELF targets.  When renaming sections, the
named section symbol needs to be renamed too.

Rather than fix this bug, I'd originally intended to just correct the
xfail added recently for update-1.o vs update4.o in update-section.exp,
using the same set of targets for the localize-hidden-1 mips xfail.
I'd extracted that target test into a new function, is_bad_symtab.  It
turns out to be useful in readelf.exp too.

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.

c68c163716 Adjust the output section size to skip gap fills
In objcopy, copy_object calls copy_section to copy contents of input
section to output section.  When --gap-fill= is used, objcopy extends
the size of output sectios to fill gaps between output sections with
gap fills.  In this case, we adjust the output section size to skip
gap files to avoid reading beypond the input section buffer before
calling copy_section and restore the output section size after input
sections have been copied.

0b45135ec1 objcopy: Improve wildcard matching for symbols with '!' prefix.
When using options such as --localize-symbol, --globalize-symbol, etc,
along with the --wildcard option, prefixing a symbol name with '!'
should provide non-matching behaviour, as example the following example
is given in the manual:

    --wildcard --weaken-symbol !foo --weaken-symbol fo*

which should weaken all symbols matching the pattern 'fo*', but not the
symbol 'foo'.

However, this currently does not work, the current logic will waken all
symbols matching the pattern 'fo*' AND all symbols that are not 'foo'.
The symbol 'foo' is covered by the first condition, and so is weakened,
while, other symbols, for example 'bar' will match the second condition,
and so be weakened.

This patch adjusts the logic so that a pattern prefixed with '!'
specifically DOES NOT apply the relevant change to any matching symbols,
instead of applying the change to all non-matching symbols.  So this:

    --weaken-symbol !foo

will ensure that the symbol 'foo' is not weakened, but says nothing
about symbols that are not 'foo'.  As a result, a pattern prefixed with
'!' now only makes sense when used alongside a more wide ranging
wildcard pattern.

This change should make the wildcard matching feature more useful, with
no overall loss of functionality.  The example given in the manual,
weaken all symbols matching 'fo*' except 'foo' can now be achieved, but
so too can more complex examples, such as weaken all symbols matching
'fo*' except 'foo', 'foa', and 'fob', like this:

    --wildcard --weaken-symbol !foo \
               --weaken-symbol !foa \
               --weaken-symbol !fob \
               --weaken-symbol fo*

Under the previous scheme, something as symbols as, weaken all symbols
except 'foo' could have been achieved with this:

    --weaken-symbol !foo

however, this will no longer work.  To achieve the same result under the
new scheme this is now required:

    --weaken-symbol !foo --weaken-symbol *

06b73f4199 objcopy: Avoid shadowing optarg.
In commit 7173b38a44 I used optarg as the

commit changes the function parameter to be called arg.

74fffc3982 Change pe/coff build-id section name to '.buildid'
The section name used to store the build-id on pe/coff is arbitrary, as it's
contents should be located using the pe/coff header's DataDirectory debug data
entry, not by using the section name.

But '.build-id' is not a good choice for that section name, as it is 9
characters long, and hence truncated to 8 characters when
--disable-long-section-names is used (which is the default, when producing an
executable with no dwarf debug sections, e.g. using ld --strip-all --build-id)

This truncation then breaks 'objcopy --only-keep-debug', which does use the
section name, due to concerns that keeping an arbitrary section which contains
the debug directory is not sensible.
