094e34f221 binutils, ld: work with --disable-libctf
This unfortunately means conditionalizing out all the libctf code, but
the result is not too unbearably ugly, if a bit repetitive.  I have
stubbed out code in the !ENABLE_LIBCTF path to avoid extra redundant
ifdefs where it seems that might be helpful.  (The stubs are not too
disruptive, but I've tried to keep them on one line where possible to
avoid filling up the screen with stubs that nobody would care about.
If this is too much of a coding style violation I can change it.)

Changes since v2: use GCC_ENABLE rather than repeating all the
                  AC_ARG_ENABLE stuff over and over again.

2a1bb84c67 x86: fix processing of -M disassembler option
Multiple -M options can be specified in any order. Therefore stright
assignment to fields affected needs to be avoided, such that earlier
options' effects won't be discarded. This was in particular a problem
for -Msuffix followed by certain of the other sub-options.

While updating documentation, take the liberty and also drop the
redundant mentioning of being able to comma-separate multiple options.

d11a9fabab objcopy: Mention 'entry address' in description
The ELF header contains a start address, which is also sometimes
called the entry address.  The 'objdump -x' output calls this field
the 'start address', while readelf calls it 'entry point address'.
The linker talks about setting the 'entry' point in its manual.

I've always thought of this field as the 'entry address', and so when
I recently wanted to know if objcopy could adjust this field I opened
up the manual and searched for 'entry', which found no hits.

I thought it would be useful (for people like me) if the description
of 'set-start' and 'adjust-start' in the objcopy manual mentioned the
word 'entry' to make it easier to find.

binutils/ChangeLog:

	* doc/binutils.texi: Mention 'entry address' in the set-start and
	adjust-start options descriptions.

9979ab6663 binutils: doc: move artifacts back to MAINTAINERCLEANFILES
In commit 2b44a6a237 (" binutils: doc: make `make clean` clean more
things"), I moved the doc build artifacts to MOSTLYCLEANFILES, which
made them get removed by "make clean".

Because generating binutils.info requires makeinfo, and we do not want
to require makeinfo when building from the tarball, binutils.info should
not get removed by "make clean" (otherwise, it won't be included in the
tarball).

And to be consistent with other projects (e.g. ld and gas), we also want
to ship the built man pages in the tarball.

This patch puts back all these in MAINTAINERCLEANFILES, so that they are
bundled in the tarball, and only cleaned if you use "make
maintainer-clean".

Tested by building a source release and confirming they are present.

301a9420d9 Add support for debuginfod to the binutils (disable by default, enabled via a configure time option).
debuginfod is a lightweight web service that indexes ELF/DWARF
debugging resources by build-id and serves them over HTTP. This patch
enables objdump and readelf to query debuginfod servers when they are
otherwise not able to find separate debug files. Binutils can be built
with debuginfod using the --with-debuginfod configure option. This
requires that libdebuginfod be installed and found at configure time.
debuginfod is packaged with elfutils, starting with version 0.178. For
more information see https://sourceware.org/elfutils/.

fd86991bc5 objdump: get CTF parent importing right
The linker emits CTF into a single section named .ctf, which is a CTF
archive where the default member (itself named ".ctf", or simply NULL)
is the parent of all other members.  Teach objdump to look for this by
default, rather than only trying to do it if a specific CTF parent
section was specified.  (If no parent name is specified, we get the .ctf
member from the same section as everything else, which matches what the
linker generates.)

2b44a6a237 binutils: doc: make make clean clean more things
There is a bunch of things left over after a `make clean` in the doc
directory.  This patch changes the Makefile so that everything built by
make is cleaned:

- man pages (the man_MANS variable)
- cxxfilt.man
- binutils.info

I am not sure why the last one was in MAINTAINERCLEANFILES.  It's
generated from binutils.texi using makeinfo, and it's not particularly
long to build, so I don't see why it shouldn't be cleaned like the other
files.

Note: with my automake 1,15.1 (built from source), I get a spurious diff
in Makefile.in, where the

  runstatedir = @runstatedir@

95103a8419 binutils: doc: remove stale things from Makefile
The `install-data-local: install-info` part: the comment refers to when
the Makefile had the cygnus option.  It no longer uses that, so the info
file should get installed without that rule.  I verified that `make
install` still installed $(prefix)/share/info/binutils.info.

using 1.15.1, which doesn't appear to have this problem.  binutils.info
is built fine without this snippet.

7d9813f196 binutils: CTF support for objdump and readelf
This introduces CTF support for objdump and readelf.  objdump has the
following new arguments:

     --ctf=SECTION: display CTF in the given SECTION
     --ctf-parent=SECTION: name of CTF section that is the parent of this section

readelf has the above, and these two as well:

     --ctf-symbols=SECTION: name of symbol table section (optional)
     --ctf-strings=SECTION: name of string table section (optional)

(objdump can always use BFD machinery to determine the applicable string
and symbol tables automatically, so these arguments are unnecessary.)

Nearly all the work is done by the ctf_dump machinery in libctf: most of
the remaining work is option-processing and section-reading, and thus is
different for objdump and readelf: the minimal amount of similar code
remaining is, in my view, too small to share, particularly given that
objdump uses ctf_bfdopen() and readelf uses ctf_simple_open() since it
doesn't have a bfd.

I am not particularly satisfied with the way resources are freed in
either of these (I was forced to do it at the top level, for lack of
anywhere else to free resources allocated during option processing), but
I can't see any better way to do it without introducing new
infrastructure for no other purpose.

There are essentially arbitrary ordering changes to the Makefile.in's
order of libtool-related stuff that I can't get rid of, but they have no
semantic effect.  (It is possible that some hunks of these changes could
be dropped, but that seems a bit risky to me.)

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.
