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.)

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@
line gets removed. I am not sure why, but I haven't included it.

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

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.)

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.

This is the result of an email thread starting here:
https://sourceware.org/ml/binutils/2018-09/msg00031.html
The main point of the thread is this observation:
* Supposing we had an object file with two globals, SomeGlobal and
SomeOtherGlobal, if one were to do "--globalize-symbol SomeGlobal
--keep-global-symbol SomeOtherGlobal", you might expect that both
SomeGlobal and SomeOtherGlobal are global in the output file... but it
isn't. Because --keep-global-symbol is set and doesn't include
SomeGlobal, SomeGlobal will be demoted to a local symbol. And because
the check to see if we should apply the --globalize-symbol flag checks
"flags" (the original flag set), and not "sym->flags", it decides not
to do anything, so SomeGlobal remains a local symbol. Although this is
a weird edge case, should this be changed so that --keep-global-symbol
implicitly keeps anything also specified via --globalize-symbol? (The
code seems technically correct with respect to the documentation, but
IMO the behavior is counter-intuitive).

--keep-global-symbol(s) and the --globalize-symbol(s) options are

BFD handles ELF relocation sections in an executable differently to
relocation sections in a relocatable object. For a relocatable
object, BFD carries the relocations as data associated with the
section to which they apply; The relocation section doesn't appear as
a separate section. For an executable, dynamic relocation sections do
appear as separate sections. This means that objcopy needs to use
different strategies when dealing with relocations.
When --remove-relocations was added to objcopy with commit
d3e5f6c8f1, objcopy lost the ability to remove dynamic relocation
sections such as .rela.plt from executables using the option
"--remove-section=.rela.plt". This patch reinstates that
functionality.
I thought it best to keep --remove-relocations as is, rather than
extending to handle dynamic relocations as per the patch in the PR,
because executables linked with --emit-relocs may have both dynamic
and non-dynamic relocations. In that case --remove-relocataions=* is
useful to remove all the non-dynamic relocations.

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).

Also make the automake strictness "foreign". My regeneration of the

When trying to run the update-gnulib.sh script in gdb, I get this:
Error: Wrong automake version (Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/\${ <-- HERE ([^ =:+{}]+)}/ at /opt/automake/1.11.1/bin/automake line 4113.), we need 1.11.1.
Aborting.
Apparently, it's an issue with a regex in automake that triggers a
warning starting with Perl 5.22. It has been fixed in automake 1.15.1.
So I think it's a good excuse to bump the versions of autoconf and
automake used in the gnulib import. And to avoid requiring multiple
builds of autoconf/automake, it was suggested that we bump the required
version of those tools for all binutils-gdb.
For autoconf, the 2.69 version is universally available, so it's an easy
choice. For automake, different distros and distro versions have
different automake versions. But 1.15.1 seems to be the most readily
available as a package. In any case, it's easy to build it from source.
I removed the version checks from AUTOMAKE_OPTIONS and AC_PREREQ,
because I don't think they are useful in our case. They only specify a
lower bound for the acceptable version of automake/autoconf. That's
useful if you let the user choose the version of the tool they want to
use, but want to set a minimum version (because you use a feature that
was introduced in that version). In our case, we force people to use a
specific version anyway. For the autoconf version, we have the check in
config/override.m4 that enforces the version we want. It will be one
less thing to update next time we change autotools version.
I hit a few categories of problems that required some changes. They are
described below along with the chosen solutions.
Problem 1:
configure.ac:17: warning: AM_INIT_AUTOMAKE: two- and three-arguments forms are deprecated. For more info, see:
configure.ac:17: http://www.gnu.org/software/automake/manual/automake.html#Modernize-AM_005fINIT_005fAUTOMAKE-invocation
Solution 1:
Adjust the code based on the example at that URL.
Problem 2 (in zlib/):
Makefile.am: error: required file './INSTALL' not found
Makefile.am: 'automake --add-missing' can install 'INSTALL'
Makefile.am: error: required file './NEWS' not found
Makefile.am: error: required file './AUTHORS' not found
Makefile.am: error: required file './COPYING' not found
Makefile.am: 'automake --add-missing' can install 'COPYING'
Solution 2:
Add the foreign option to AUTOMAKE_OPTIONS.
Problem 3:
doc/Makefile.am:20: error: support for Cygnus-style trees has been removed
Solution 3:
Remove the cygnus options.
Problem 4:
Makefile.am:656: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS')
Solution 4:
Rename "INCLUDES = " to "AM_CPPFLAGS += " (because AM_CPPFLAGS is
already defined earlier).
Problem 5:
doc/Makefile.am:71: warning: suffix '.texinfo' for Texinfo files is discouraged; use '.texi' instead
doc/Makefile.am: warning: Oops!
doc/Makefile.am: It appears this file (or files included by it) are triggering
doc/Makefile.am: an undocumented, soon-to-be-removed automake hack.
doc/Makefile.am: Future automake versions will no longer place in the builddir
doc/Makefile.am: (rather than in the srcdir) the generated '.info' files that
doc/Makefile.am: appear to be cleaned, by e.g. being listed in CLEANFILES or
doc/Makefile.am: DISTCLEANFILES.
doc/Makefile.am: If you want your '.info' files to be placed in the builddir
doc/Makefile.am: rather than in the srcdir, you have to use the shiny new
doc/Makefile.am: 'info-in-builddir' automake option.
Solution 5:
Rename .texinfo files to .texi.
Problem 6:
doc/Makefile.am: warning: Oops!
doc/Makefile.am: It appears this file (or files included by it) are triggering
doc/Makefile.am: an undocumented, soon-to-be-removed automake hack.
doc/Makefile.am: Future automake versions will no longer place in the builddir
doc/Makefile.am: (rather than in the srcdir) the generated '.info' files that
doc/Makefile.am: appear to be cleaned, by e.g. being listed in CLEANFILES or
doc/Makefile.am: DISTCLEANFILES.
doc/Makefile.am: If you want your '.info' files to be placed in the builddir
doc/Makefile.am: rather than in the srcdir, you have to use the shiny new
doc/Makefile.am: 'info-in-builddir' automake option.
Solution 6:
Remove the hack at the bottom of doc/Makefile.am and use
the info-in-builddir automake option.
Problem 7:
doc/Makefile.am:35: error: required file '../texinfo.tex' not found
doc/Makefile.am:35: 'automake --add-missing' can install 'texinfo.tex'
Solution 7:
Use the no-texinfo.tex automake option. We also have one in
texinfo/texinfo.tex, not sure if we should point to that, or move it
(or a newer version of it added with automake --add-missing) to
top-level.
Problem 8:
Makefile.am:131: warning: source file 'config/tc-aarch64.c' is in a subdirectory,
Makefile.am:131: but option 'subdir-objects' is disabled
automake: warning: possible forward-incompatibility.
automake: At least a source file is in a subdirectory, but the 'subdir-objects'
automake: automake option hasn't been enabled. For now, the corresponding output
automake: object file(s) will be placed in the top-level directory. However,
automake: this behaviour will change in future Automake versions: they will
automake: unconditionally cause object files to be placed in the same subdirectory
automake: of the corresponding sources.
automake: You are advised to start using 'subdir-objects' option throughout your
automake: project, to avoid future incompatibilities.
Solution 8:
Use subdir-objects, that means adjusting references to some .o that will now
be in config/.
Problem 9:

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.
