This changes the gdbserver build to use the gdbsupport that was built
for gdb.
gdbserver and gdbreplay now must use WIN32APILIBS (aka -lws2_32).
Before this change, gdbserver did not define USE_WIN32API when
building gdbsupport, but now this is always done.

This changes gdbsupport so that it no longer relies on BFD. This is a
precursor to making gdbserver use the already-built gdbsupport,
because building gdbserver should not require BFD to be built.
The most notable change here is that CORE_ADDR is always a 64-bit
type. This makes it so that gdb acts as if it were always built in
64-bit mode.

gdbserver uses gdb's alloc.c, and this in turn can include headers
from intl via gdbsupport/gdb_locale.h. This can cause build failures
in some situations, for example if you build gdb and gdbserver on
mingw.
This patch restores the gdbsupport dependency on intl, and changes
gdbserver to use ZW_GNU_GETTEXT_SISTER_DIR. This fixes this build
problem.

An earlier patch changed gdbserver to use the already-built top-level
gnulib and gdbsupport. However, if one did a build that did not
include gdb, then gdbserver would fail to build.
The problem is that configure.ac only adds gnulib and gdbsupport to
the build when gdb is being built. This patch fixes the problem by
arranging for this to happen when gdbserver is built.

This changes gdbserver so that it no longer builds its own gnulib and

This patch moves gdbserver to the top level.
This patch is as close to a pure move as possible -- gdbserver still
builds its own variant of gnulib and gdbsupport. Changing this will
be done in a separate patch.
[v2] Note that, per Simon's review comment, this patch changes the
tree so that gdbserver is not built for or1k or score. This makes
sense, because there is apparently not actually a gdbserver port here.
[v3] This version of the patch also splits out some configury into a
new file, gdbserver/configure.host, so that the top-level configure
script can simply rely on it in order to decide whether gdbserver
should be built.
[v4] This version adds documentation and removes some unnecessary
top-level dependencies.
[v5] Update docs to mention "make all-gdbserver" and change how
top-level configure decides whether to build gdbserver, switching to a
single, shared script.
Tested by the buildbot.

The move of gdbsupport to the top level directory requires a small
change to src-release.sh's "getver" function, which is responsible for
determining the version string that will be appended to the release
tarball: now the create-version.sh script lives under ./gdbsupport,
and not under gdb/gdbsupport anymore.
This patch unbreaks the snapshot generation, which hasn't been working
since January 14th.

When running a program with the simulator target, I get:
/home/simark/src/binutils-gdb/gdb/inferior.c:279: internal-error: inferior* find_inferior_pid(process_stratum_target*, int): Assertion `pid != 0' failed.
This can be reproduced by building a GDB for --target=arm-none-gnueabi,
and running with
$ ./gdb -nx --data-directory=data-directory a.out -ex "target sim" -ex load -ex "b main" -ex r
Where a.out is any program with a main.
The problem is that gdbsim_target::wait assumes that inferior_ptid has
the value of the thread it wants to report an event for.
Actually, it's the target's responsibility to come up with the ptid of
the thread the event is for. In the sim target, that ptid is stored in
sim_inferior_data::remote_sim_ptid, so return that instead of
inferior_ptid.
ChangeLog:
* remote-sim.c (gdbsim_target::wait): Return
sim_data->remote_sim_ptid instead of inferior_ptid.

This patch moves the gdbsupport directory to the top level. This is
the next step in the ongoing project to move gdbserver to the top
level.
The bulk of this patch was created by "git mv gdb/gdbsupport gdbsupport".
This patch then adds a build system to gdbsupport and wires it into
the top level. Then it changes gdb to use the top-level build.
gdbserver, on the other hand, is not yet changed. It still does its
own build of gdbsupport.

* src-release.sh (getver): Replace "head -1" with "head -n 1".
This lets other programs read and write CTF-format data.
Two versioned shared libraries are created: libctf.so and
libctf-nobfd.so. They contain identical content except that
libctf-nobfd.so contains no references to libbfd and does not implement
ctf_open, ctf_fdopen, ctf_bfdopen or ctf_bfdopen_ctfsect, so it can be
used by programs that cannot use BFD, like readelf.
The soname major version is presently .0 until the linker API
stabilizes, when it will flip to .1 and hopefully never change again.

This is quite complicated because the CTF section's contents depend on
the final contents of the symtab and strtab, because it has two sections
whose contents are shuffled to be in 1:1 correspondence with the symtab,
and an internal strtab that gets deduplicated against the ELF strtab
(with offsets adjusted to point into the ELF strtab instead). It is
also compressed if large enough, so its size depends on its contents!
So we cannot construct it as early as most sections: we cannot even
*begin* construction until after the symtab and strtab are finalized.
Thankfully there is already one section treated similarly: compressed
debugging sections: the only differences are that compressed debugging
sections have extra handling to deal with their changing name if
compressed (CTF sections are always called ".ctf" for now, though we
have reserved ".ctf.*" against future use), and that compressed
debugging sections have previously-uncompressed content which has to be
stashed away for later compression, while CTF sections have no content
at all until we generate it (very late).
BFD also cannot do the link itself: libctf knows how to do it, and BFD
cannot call libctf directly because libctf already depends on bfd for
file I/O. So we have to use a pair of callbacks, one, examine_strtab,
which allows a caller to examine the symtab and strtab after
finalization (called from elf_link_swap_symbols_out(), right before the
symtabs are written, and after the strtab has been finalized), and one
which actually does the emission (called emit_ctf simply because it is
grouped with a bunch of section-specific late-emission function calls at
the bottom of bfd_elf_final_link, and a section-specific name seems best
for that). emit_ctf is actually called *twice*: once from lang_process
if the emulation suggests that this bfd target does not examine the
symtab or strtab, and once via a bfd callback if it does. (This means
that non-ELF targets still get CTF emitted, even though the late CTF
emission stage is never called for them).
v2: merged with non-ELF support patch: slight commit message
adjustments.
v3: do not spend time merging CTF, or crash, if the CTF section is
explicitly discarded. Do not try to merge or compress CTF unless
linking.
v4: add CTF_COMPRESSION_THRESHOLD. Annul the freed input ctf_file_t's
after writeout: set SEC_IN_MEMORY on the output contents so a future
bfd enhancement knows it could free it. Add SEC_LINKER_CREATED |
SEC_KEEP to avoid having to add .ctf to the linker script. Drop
now-unnecessary ldlang.h-level elf-bfd.h include and hackery around
it. Adapt to elf32.em->elf.em and elf-generic.em->ldelf*.c
changes.
v5: fix tabdamage. Drop #inclusions in .h files: include in .c files,

gdb should normally not be linked with -static-libstdc++. Currently
this has not caused problems, but it's incompatible with catching an
exception thrown from a shared library -- and a subsequent patch
changes gdb to do just this.
This patch adds a new --with-static-standard-libraries flag to the
top-level configure. It defaults to "auto", which means enabled if
gcc is being built, and disabled otherwise.
ChangeLog
2019-08-19 Tom Tromey <tom@tromey.com>
* configure: Rebuild.
* configure.ac: Add --with-static-standard-libraries.
A recent change renamed the common/ directory into gdbsupport/ in gdb.
This causes problems in the getver function in the src-release script
which doesn't find the create-version.sh script anymore. As a result,
it falls back on using the version.in file verbatim, meaning that
the "DATE" placeholder doesn't get replaced with the snapshot date,
and the "-git" suffix doesn't get stripped. More precisely, we get
snapshots called "gdb-8.3.50-DATE-git.tar" instead of (e.g.)
"gdb-8.3-20190712.tar".
This commit fixes the issue by adding support for this situation.
I left the support for $tool/common/create-version.sh, because
the sim still uses that directory structure.
ChangeLog:
* src-release (getver): If $tool/gdbsupport/create-version.sh
exists, use that to determine the version number.
This patch moves the gdb/gnulib subdirectory to the top level.
It adjusts the top-level build system to build gnulib when necessary,
and changes gdb to use this. However, gdbserver still builds its own
copy of gnulib, just from the new source location.
A small hack was needed to ensure that gnulib is only built when gdb
is enabled. The Makefile only provides an ordering -- the directory
must be mentioned in configdirs to actually be compiled at all.
Most of the patch is just a "git mv" of gnulib, though a few minor
path adjustments were needed in some files there.
Tested by the buildbot.

Update dg-extract-results.* from gcc
dg-extract-results.sh was moved from the "gdb/contrib/" directory to
the toplevel "contrib/" directory. However, src-release.sh was not
updated in order to include "contrib/" in the tarball release of GDB.
This makes it very inconvenient to run and analyze the GDB testsuite
results. This commit adds "contrib/" to the list of support
directories that are included in each GDB release.

* src-release.sh (GDB_SUPPORT_DIRS): Add "contrib".
This patch turns dependencies of non-bootstrap targets on bootstrap
targets for bootstrap builds into dependencies on stage_last. This
arrangement gets stage1-bubble to run from stage_last if we haven't
started a bootstrap yet, and to use the current stage otherwise. This
was already the case of target libs, just not of non-bootstrapped host
modules.
In order to retain preexisting dependencies in non-bootstrap builds,
or in gcc-less builds, this introduces support for @unless/@endunless
pairs in Makefile.in.
There is a remaining possibility of problem if activating, in a tree
configured for bootstrap, a parallel build of two or more modules, at
least one bootstrapped and one not. In this case, make might decide
to build stage_current and stage_last in parallel, the latter will
start a submake to build stage1 while the initial make, having
satisfied stage_current, proceeds to build the bootstrapped module in
non-bootstrapped configurations. The two builds will overlap and will
likely conflict. This situation does NOT arise in normal settings,
however: a post-bootstrap build of all-host all-target will indeed
activate such targets concurrently, but only after building all
bootstrapped modules successfully, and it will have both stage_last
and stage_current targets already satisfied, so the potential race
between builds will not arise.
Another remaining problem, that is slightly expanded with this patch,
is that of an interrupted build in a tree configured for bootstrap,
continued with a non-bootstrapped target. Target modules that were
not bootstrapped would already fail to complete the current stage when
activated explicitly in the command line for a retry; host modules,
however, would attempt to build their bootstrapped dependencies, which
is what led to the problem of concurrent builds addressed with this
patch. An interrupted or failed build might still recover correctly,
if the non-bootstrapped target is activated in both builds, because
then make will remove stage_last when its build command is
interrupted, so that it will attempt to recreate it with stage1-bubble
in the second try. A bootstrap build, however, will not be attempting
to build stage_last, so the file will remain and the retry won't go
through stage1-bubble. We have lived with that for target modules, so
we can probably live with that for host modules too.
Another undesirable consequence of this change is that non-boostrapped
host modules, in a tree configured for bootstrap, when activated as
make all-<module>, will build all of stage1 instead of only the
module's usual dependencies. This is intentional and necessary to fix
the parallel-build problem. If it's not desirable, disabling the
unnecessary bootstrap configuration will suffice to restore the
original set of dependencies.
