remote testing. This is because the binary files weren't being copied over to
the remote host for testing.

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.

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*'.

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.

Mixing MIPS16 and microMIPS code in a single binary isn't usually
supported but GAS happily produces such code if requested. However it
is not correctly disassembled even if a symbol table is available and
function symbols are correctly anotated with the ISA mode. This is
because the ELF-header global microMIPS ASE flag takes precedence over
MIPS16 function annotation, causing them to be treated as regular MIPS
code.
Correct the problem by respecting function symbol anotation regardless
of the ELF-header flag.

Correct a regression introduced with commit 685080f21003 ("Adds support
for generating notes in V850 binaries.") which replaced rather than
extending the call to `_bfd_elf_copy_private_bfd_data' with
`v850_elf_copy_private_bfd_data'. Consequently ELFOSABI_GNU marking is
not propagated to output by `objcopy' from objects containing
STB_GNU_UNIQUE symbols.

This commit restructures the selection of the default cpu/mach so that
the choice is made from md_begin (if the user has not provided a command
line choice). This will reduce the amount of change needed in a later
patch.
At the request of Synopsys, the default architecture changes to ARC700
from this commit, previously the default was a non-existent
super-architecture that contained all instructions from all arc
variants. There's some clean up associated with removing the default
merged architecture, and a small test fix now that the default is
ARC700.

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.

When the DWARF address size is 32-bit, but the host machine is 64-bit,
objdump fails to spot base addresses specified in the .debug_ranges and
.debug_loc lists.
As an example, here is the output when dumping an example .debug_ranges
section with the pre-patched objdump:
Contents of the .debug_ranges section:
Offset Begin End
00000000 ffffffff 00000004 (start > end)
00000000 00000000 00000004
00000000 ffffffff 00000008 (start > end)
00000000 00000000 00000004
00000000 <End of list>
And this is what the same section looks like when dumped with the
patched version of objdump:
Contents of the .debug_ranges section:
Offset Begin End
00000000 ffffffff 00000004 (base address)
00000000 00000004 00000008
00000000 ffffffff 00000008 (base address)

When copying the sh_link and sh_info fields in stripped section headers,
we also check if the sh_type, sh_flags, /sh_addralign and sh_entsize
fields of the output section match the output. Since --only-keep-debug
turns all non-debug sections into SHT_NOBITS sections, the output
SHT_NOBITS type matches any input type.

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 *

The output SHF_COMPRESSED section size is different from input if
ELF classes of input and output aren't the same. We must adjust
the section sizes as well as the compression headers in
SHF_COMPRESSED sections when converting objects between different
