This option has been present since the very early days of the
development of libctf as part of binutils, and it shows. Back in the
earliest days, I thought we might handle ambiguous types by introducing
new ELF sections on the fly named things like .ctf.foo.c for ambiguous
types found only in foo.c, etc. This turned out to be a terrible idea,
so we moved to using a CTF archive in the .ctf section which contained
all the CTF dictionaries -- but the --ctf-parent option in objdump and
readelf was never adjusted, and lingered as a mechanism to specify CTF
parent dictionaries in sections other than .ctf, even though the linker
has no way to produce parent dictionaries in different sections from
their children, libctf's ctf_open can't handle such split-up
parent/child dicts, and they are never found in the wild, emitted by GNU
ld or by any known third-party linking tool.
Meanwhile, the actually-useful ctf_link feature (albeit not used by ld)
which lets you remap the names of CTF archive members (so you can end up
with a parent archive member named something other than ".ctf", still
contained with all its children in a single .ctf section) had no support
in objdump or readelf: there was no way to tell them that these members
were parents, so all the types in the associated child dicts always
appeared corrupted, referencing nonexistent types from a parent objdump
couldn't find.
So adjust --ctf-parent so that rather than taking a section name it
takes a member name instead (if not specified, the name is ".ctf", which
is what GNU ld emits). Because the option was always useless before
now, this is expected to have no backward-compatibility implications.
As part of this, we have to slightly adjust the code which skips the
archive member name if redundant: right now it skips it if it's ".ctf",
on the assumption that this name will almost always be at the start
of the objdump output and thus we'll end up with a shared dump
and then smaller, headed dumps for the per-TU child dicts; but if
the parent name has been changed, that won't be true any more.
So change the rules to "members named .ctf which appear first in the
first have their member name skipped". Since we now need to count
members, move from ctf_archive_iter (for which passing in extra
parameters requires defining a new struct and is clumsy) to
ctf_archive_next, allowing us to just *call* dump_ctf_archive_member and
maintain a member count in the obvious way. In the process we fix a
tiny difference between readelf and objdump: if a ctf_dump ever failed,
readelf skipped every later member, while objdump tried to keep going as
much as it could. For a dumping tool the former is clearly preferable.

2021-10-25 Nick Alcock <nick.alcock@oracle.com>
* objdump.c (usage): --ctf-parent now takes a name, not a section.
(dump_ctf): Don't open a separate section; use the parent_name in
ctf_dict_open instead. Use ctf_archive_next, not ctf_archive_iter,
so we can pass down a member count.
(dump_ctf_archive_member): Add the member count; don't return
anything. Import parents into children no matter what the
parent's name, while still avoiding displaying the header for the
common parent name of ".ctf".
* readelf.c (usage): Adjust similarly.
(dump_section_as_ctf): Likewise.
(dump_ctf_archive_member): Likewise. Never stop iterating over
archive members, even if ctf_dump of one member fails.

* windres.c (quot): Revert previous delta. Do not use double
quotes when spaces are detected in options.
* doc/binutils.texi (windres): Remove suggestion that the
--preprocessor option can take arguments.
Use the pattern from other projects where we generate the html pages
in a dir named the same as the project. So now we have:
gas/doc/gas.html - single html page
gas/doc/gas/ - multiple html pages
This works for projects that have a doc/ subdir already, but gprof &
ld require a little tweaking since they generate their docs in their
respective toplevels.
This better matches other GNU projects like autoconf/automake where
the html manual is the single page form. We'll support the multi-page
form in a follow up change.

GDB currently doesn't build on 32-bit Solaris:
* On Solaris 11.4/x86:
In file included from /usr/include/sys/procfs.h:26,
from /vol/src/gnu/gdb/hg/master/dist/gdb/i386-sol2-nat.c:24:
/usr/include/sys/old_procfs.h:31:2: error: #error "Cannot use procfs in the large file compilation environment"
#error "Cannot use procfs in the large file compilation environment"
^~~~~
* On Solaris 11.3/x86 there are several more instances of this.
The interaction between procfs and large-file support historically has
been a royal mess on Solaris:
* There are two versions of the procfs interface:
** The old ioctl-based /proc, deprecated and not used any longer in
either gdb or binutils.
** The `new' (introduced in Solaris 2.6, 1997) structured /proc.
* There are two headers one can possibly include:
** <procfs.h> which only provides the structured /proc, definining
_STRUCTURED_PROC=1 and then including ...
** <sys/procfs.h> which defaults to _STRUCTURED_PROC=0, the ioctl-based
/proc, but provides structured /proc if _STRUCTURED_PROC == 1.
* procfs and the large-file environment didn't go well together:
** Until Solaris 11.3, <sys/procfs.h> would always #error in 32-bit
compilations when the large-file environment was active
(_FILE_OFFSET_BITS == 64).
** In both Solaris 11.4 and Illumos, this restriction was lifted for
structured /proc.
So one has to be careful always to define _STRUCTURED_PROC=1 when
testing for or using <sys/procfs.h> on Solaris. As the errors above
show, this isn't always the case in binutils-gdb right now.
Also one may need to disable large-file support for 32-bit compilations
on Solaris. config/largefile.m4 meant to do this by wrapping the
AC_SYS_LARGEFILE autoconf macro with appropriate checks, yielding
ACX_LARGEFILE. Unfortunately the macro doesn't always succeed because
it neglects the _STRUCTURED_PROC part.
To make things even worse, since GCC 9 g++ predefines
_FILE_OFFSET_BITS=64 on Solaris. So even if largefile.m4 deciced not to
enable large-file support, this has no effect, breaking the gdb build.
This patch addresses all this as follows:
* All tests for the <sys/procfs.h> header are made with
_STRUCTURED_PROC=1, the definition going into the various config.h
files instead of having to make them (and sometimes failing) in the
affected sources.
* To cope with the g++ predefine of _FILE_OFFSET_BITS=64,
-U_FILE_OFFSET_BITS is added to various *_CPPFLAGS variables. It had
been far easier to have just
#undef _FILE_OFFSET_BITS
in config.h, but unfortunately such a construct in config.in is
commented by config.status irrespective of indentation and whitespace
if large-file support is disabled. I found no way around this and
putting the #undef in several global headers for bfd, binutils, ld,
and gdb seemed way more invasive.
* Last, the applicability check in largefile.m4 was modified only to
disable largefile support if really needed. To do so, it checks if
<sys/procfs.h> compiles with _FILE_OFFSET_BITS=64 defined. If it
doesn't, the disabling only happens if gdb exists in-tree and isn't
disabled, otherwise (building binutils from a tarball), there's no
conflict.
What initially confused me was the check for $plugins here, which
originally caused the disabling not to take place. Since AC_PLUGINGS
does enable plugin support if <dlfcn.h> exists (which it does on
Solaris), the disabling never happened.
I could find no explanation why the linker plugin needs large-file
support but thought it would be enough if gld and GCC's lto-plugin
agreed on the _FILE_OFFSET_BITS value. Unfortunately, that's not
enough: lto-plugin uses the simple-object interface from libiberty,
which includes off_t arguments. So to fully disable large-file
support would mean also disabling it in libiberty and its users: gcc
and libstdc++-v3. This seems highly undesirable, so I decided to
disable the linker plugin instead if large-file support won't work.
The patch allows binutils+gdb to build on i386-pc-solaris2.11 (both
Solaris 11.3 and 11.4, using GCC 9.3.0 which is the worst case due to
predefined _FILE_OFFSET_BITS=64). Also regtested on
amd64-pc-solaris2.11 (again on Solaris 11.3 and 11.4),
x86_64-pc-linux-gnu and i686-pc-linux-gnu.

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.)

up the manual and searched for 'entry', which found no hits.

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.
