The ARM simulator is no longer able to simulator modern ARM cores, so it
is being deprecated. Once this change has been active for a while - and
assuming that no problems have been found - the ARm simulator codebase
will be removed.

Commit e5f2f7d901ee ("Disable year 2038 support on 32-bit hosts by
default") fixed a mismatch between 64-bit time_t in GDB and system headers
and 32-bit time_t in BFD.
However, since commit 862776f26a59 ("Finalized intl-update patches")
gnulib's year 2038 support has been accidentally re-enabled — causing
problems for 32-bit hosts again. The commit split baseargs into
{h,b}baseargs, but this hasn't been done for the code that handles
--disable-year2038.
This patch restores the intended behaviour. With this change, the number
of unexpected core files goes from 18 to 4.
Tested on armv8l-linux-gnueabihf.

Pass GUILE down to subdirectories
When I enable cgen rebuilding in the binutils-gdb tree, the default is
to run cgen using 'guile'. However, on my host, guile is guile 2.2,
which doesn't work for me -- I have to use guile3.0.
This patch arranges to pass "GUILE" down to subdirectories, so I can
use 'make GUILE=guile3.0'.

Makefile.tpl: Avoid race condition in generating site.exp from the top level
A command like "make -j 2 check-gcc-c check-gcc-c++" run in the top level of
a fresh build directory does not work reliably. That will spawn two
independent make processes inside the "gcc" directory, and each of those
will attempt to create site.exp if it doesn't exist and will interfere with
each other, producing often a corrupted or empty site.exp. Resolve that by
making these targets depend on a new phony target which makes sure site.exp
is created first before starting the recursive makes.

Config,Darwin: Allow for configuring Darwin to use embedded runpath.
Recent Darwin versions place contraints on the use of run paths
specified in environment variables. This breaks some assumptions
in the GCC build.
This change allows the user to configure a Darwin build to use
'@rpath/libraryname.dylib' in library names and then to add an
embedded runpath to executables (and libraries with dependents).
The embedded runpath is added by default unless the user adds
'-nodefaultrpaths' to the link line.
For an installed compiler, it means that any executable built with
that compiler will reference the runtimes installed with the
compiler (equivalent to hard-coding the library path into the name
of the library).
During build-time configurations any "-B" entries will be added to
the runpath thus the newly-built libraries will be found by exes.
Since the install name is set in libtool, that decision needs to be
available here (but might also cause dependent ones in Makefiles,
so we need to export a conditional).
This facility is not available for Darwin 8 or earlier, however the
existing environment variable runpath does work there.
We default this on for systems where the external DYLD_LIBRARY_PATH
does not work and off for Darwin 8 or earlier. For systems that can
use either method, if the value is unset, we use the default (which
is currently DYLD_LIBRARY_PATH).

that we need to have $srcdir in the generated #line reference back to

Since 991180627851801f1999d1ebbc0e569a17e47c74, the configure checks
about GMP and MPFR for gdb builds have been moved to the toplevel
configure.
However, it doesn't take into account the --disable-gdb option. Meaning
that a build without gdb will require these libraries even if not
needed.
ChangeLog:
* configure.ac: Skip GMP and MPFR when --disable-gdb is
provided.
* configure: Regenerate.
|

This patch uses the toplevel configure parts for GMP/MPFR for
gdb. The only thing is that gdb now requires MPFR for building.
Before it was a recommended but not required library.
Also this allows building of GMP and MPFR with the toplevel
directory just like how it is done for GCC.
We now error out in the toplevel configure of the version
of GMP and MPFR that is wrong.
OK after GDB 13 branches? Build gdb 3 ways:
with GMP and MPFR in the toplevel (static library used at that point for both)
With only MPFR in the toplevel (GMP distro library used and MPFR built from source)
With neither GMP and MPFR in the toplevel (distro libraries used)

libsframe is a library that allows you to:
- decode a .sframe section
- probe and inspect a .sframe section
- encode (and eventually write) a .sframe section.
This library is currently being used by the linker, readelf, objdump.
This library will also be used by the SFrame unwinder which is still
to be upstream'd.
The file include/sframe-api.h defines the user-facing APIs for decoding,
encoding and probing .sframe sections. A set of error codes together
with their error message strings are also defined.
Endian flipping is performed automatically at read and write time, if
cross-endianness is detected.

If zstd is not supported, ELFCOMPRESS_ZSTD input triggers an error. We
can avoid HAVE_ZSTD if binutils-gdb imports zstd/ like zlib/, but this
is too heavyweight, so don't do it for now.

Because CPPFLAGS_FOR_BUILD is used in some subdirectories (through
bfd/warning.m4), not AC_SUBSTing the variable causes minor issues.
Fortunately, it didn't cause severe errors but error messages related to
@CPPFLAGS_FOR_BUILD@ (not AC_SUBSTed CPPFLAGS_FOR_BUILD variable passed
to subdirectories through Makefile) remain in config.log.
To avoid invalid invocation of preprocessor for build environment, we
need to set proper CPPFLAGS_FOR_BUILD (may be empty) and pass it to
subdirectories that need it. This is what this commit does.
ChangeLog:
* configure.ac: Pass CPPFLAGS_FOR_BUILD to subdirectories.

With a recent import of gnulib, code has been pulled that tests and enables
64-bit time_t by default on 32-bit hosts that support it.
Although gdb can use the gnulib support, bfd doesn't use gnulib and currently
doesn't do these checks.
As a consequence, if we have a 32-bit host that supports 64-bit time_t, we'll
have a mismatch between gdb's notion of time_t and bfd's notion of time_t.
This will lead to mismatches in the struct stat size, leading to memory
corruption and crashes.
This patch disables the year 2038 check for now, which makes things work
reliably again.
I'd consider this a temporary fix until we have proper bfd checks for the year
2038, if it makes sense. 64-bit hosts seems to be more common these days, so
I'm not sure how important it is to have this support enabled and how soon
we want to enable it.
Thoughts?

This is a regression since commit a08bdb159bb ("[gdb/build] Fix gdbserver
build with -fsanitize=thread").
The problem is that a single case statement in configure is shared to handle
special requirements for both the host libiberty and host zlib, which has the
effect that only one is handled.
Fix this by handling libiberty and zlib each in its own case statement.
Build on x86_64-linux, with and without --enable-shared.

which looks similar to what is described in commit 78e49486944 ("[gdb/build]
Fix gdbserver build with -fsanitize=address").
The gdbserver component builds a shared library libinproctrace.so, which uses
libiberty and therefore requires the pic variant. The gdbserver Makefile is
setup to use this variant, if available, but it's not there.
Fix this by listing gdbserver in the toplevel configure alongside libcc1, as a
component that needs the libiberty pic variant, setting:

extra_host_libiberty_configure_flags=--enable-shared

[Sending to binutils, gdb-patches and gcc-patches, since it touches the
top-level Makefile/configure]
I have my debuginfod library installed in a non-standard location
(/opt/debuginfod), which requires me to set
PKG_CONFIG_PATH=/opt/debuginfod/lib/pkg-config. If I just set it during
configure:
$ PKG_CONFIG_PATH=/opt/debuginfod/lib/pkg-config ./configure --with-debuginfod
$ make
or
$ ./configure --with-debuginfod PKG_CONFIG_PATH=/opt/debuginfod/lib/pkg-config
$ make
Then PKG_CONFIG_PATH is only present (and ignored) during the top-level
configure. When running make (which runs gdb's and binutils'
configure), PKG_CONFIG_PATH is not set, which results in their configure
script not finding the library:
checking for libdebuginfod >= 0.179... no
configure: error: "--with-debuginfod was given, but libdebuginfod is missing or unusable."
Change the top-level configure/Makefile system to capture the value
passed when configuring the top-level and pass it down to
subdirectories (similar to CFLAGS, LDFLAGS, etc).
I don't know much about the top-level build system, so I really don't
know if I did this correctly. The changes are:
- Use AC_SUBST(PKG_CONFIG_PATH) in configure.ac, so that
@PKG_CONFIG_PATH@ gets replaced with the actual PKG_CONFIG_PATH value
in config files (i.e. Makefile)
- Add a PKG_CONFIG_PATH Makefile variable in Makefile.tpl, initialized
to @PKG_CONFIG_PATH@
- Add PKG_CONFIG_PATH to HOST_EXPORTS in Makefile.tpl, which are the
variables set when running the sub-configures
I initially added PKG_CONFIG_PATH to flags_to_pass, in Makefile.def, but
I don't think it's needed. AFAIU, this defines the flags to pass down
when calling "make" in subdirectories. We only need PKG_CONFIG_PATH to
be passed down during configure. After that, it's captured in
gdb/config.status, so even if a "make" causes a re-configure later
(because gdb/configure has changed, for example), the PKG_CONFIG_PATH
value will be remembered.
ChangeLog:
* configure.ac: Add AC_SUBST(PKG_CONFIG_PATH).
* configure: Re-generate.
* Makefile.tpl (HOST_EXPORTS): Pass PKG_CONFIG_PATH.
(PKG_CONFIG_PATH): New.
* Makefile.in: Re-generate.

Some components, e.g. zlib, are built as both host and target
libraries.
This causes problems for binutils-gdb. If we run 'make all' in the
binutils-gdb repository we end up trying to build a target version of
the zlib library, which requires the target compiler be available.
Often the target compiler isn't immediately available, and so the
build fails.
The problem with zlib impacted a previous attempt to synchronise the
top-level configure scripts from gcc to binutils-gdb, see this thread:
https://sourceware.org/pipermail/binutils/2019-May/107094.html
And I'm in the process of importing libbacktrace in to binutils-gdb,
which is also a host and target library, and triggers the same issues.
I believe that for binutils-gdb, at least at the moment, there are no
target libraries that we need to build.
In the configure script we build three lists of things we want to
build, $configdirs, $build_configdirs, and $target_configdirs, we also
build two lists of things we don't want to build, $skipdirs and
$noconfigdirs. We then remove anything that is in the lists of things
not to build, from the list of things that should be built.
My proposal is to add everything in target_configdirs into skipdirs,
if the source tree doesn't contain a gcc/ sub-directory. The result
is that for binutils-gdb no target tools or libraries will be built,
while for the gcc repository, nothing should change.
If a user builds a unified source tree, then the target tools and
libraries should still be built as the gcc/ directory will be present.
I've tested a build of gcc on x86-64, and the same set of target
libraries still seem to get built. On binutils-gdb this change
resolves the issues with 'make all'.
ChangeLog:

* configure.ac (skipdirs): Add the contents of target_configdirs if

Add the --enable-pgo-build[=lto] configure option. When binutils+gdb
is not built together with GCC, --enable-pgo-build enables the PGO build:
1. First build with -fprofile-generate.
2. Use "make maybe-check-*" to generate profiling data and pass -i to make
to ignore errors when generating profiling data.
3. Use "make clean" to remove the previous build.
4. Rebuild with -fprofile-use.
With --enable-pgo-build=lto, -flto=jobserver -ffat-lto-objects are used
together with -fprofile-generate and -fprofile-use. Add '+' to the command
line for recursive make to support -flto=jobserver -ffat-lto-objects.
NB: --enable-pgo-build=lto enables the PGO build with LTO while
--enable-lto enables LTO support in toolchain.

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 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.

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.

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/.

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.

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.
