ab27339636 readelf verdef and verneed
readelf ought to notify when a symbol wrongly has both a version
definition and a needed version.  This patch does that, and removes
the heuristic that only defined symbols in SHT_NOBITS sections have
verneed entries.

	* readelf (process_version_sections): Check DT_VERNEED and
	DT_VERDEF for all symbols.  Report "*both*" should a symbol
	have both a verneed and verdef.
	(get_symbol_version_string): Reduce indentation by early
	exits.  Don't use SHT_NOBITS heuristic to detect case where a
	defined symbol has a verneed entry.

431ff0756a avr: Fix bugs in org/align tracking.
This commit fixes a few issues in the mechanism for passing information
about ".org" and ".align" directives from the assembler to the linker,
used by the avr target.

In the original commit fdd410ac7a, there
were some mistakes when writing out information about ".align"
directives:
  - An align with fill does not write out its information correctly, the
    fill data overwrites the alignment data.
  - Each alignment directive is recorded at the location where the
    previous alignment directive should be recorded, the first alignment
    directive is discarded.

In commit 137c83d69f, the data produced by
objdump is not correct:
   - It's miss-aligned due to a missing whitespace.
   - The fill data for align with fill records is not displayed
     correctly.

All of the above issues are addressed in this commit, and the test is
improved to cover these cases.

	* od-elf32_avr.c (elf32_avr_dump_avr_prop): Fix printing of align
	specific data, fix formatting for align and org data.

	address for align records.

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.

cfe101c6a8 Missing parts of fixes for in-tree libiconv
(Commit d23d1dff missed pushing the config/iconv.m4 change, and to
regenerate binutils' configure.)

Original description:

This is the second in a series of patches to make a build with an
in-tree GNU libiconv work as designed.

Currently GDB is the only toolchain component which actually uses an
in-tree libiconv.  This patch modifies the common AM_ICONV to use an
in-tree libiconv when present and not already provided by libc.
(GDB's workaround uses an in-tree libiconv even when libc provides
iconv(3); I'm not sure when or why that would be desirable.)

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 *

19a7fe52ae Make default compression gABI compliant
All programs in binutils+gdb git repo now support gABI compression
with the SHF_COMPRESSED bit.  This patch makes the zlib-gabi option
as compression default for gas, gold, ld and objcopy, instead of the
zlib-gnu option whose outputs are incompatible with gABI.

889884731e Properly convert objects between different ELF classes
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
ELF classes.
