[PATCH] configure: Always add pre-installed header directories to search path
configure script was adding the target directory flags, including the
'-B' flags for the executable prefix and the '-isystem' flags for the
pre-installed header directories, to the target flags only for
non-Canadian builds under the premise that the host binaries under the
executable prefix will not be able to execute on the build system for
Canadian builds.
While that is true for the '-B' flags specifying the executable prefix,
the '-isystem' flags specifying the pre-installed header directories are
not affected by this and do not need special handling.
This patch updates the configure script to always add the 'include' and
'sys-include' pre-installed header directories to the target search
path, in order to ensure that the availability of the pre-installed
header directories in the search path is consistent across non-Canadian
and Canadian builds.
When '--with-headers' flag is specified, this effectively ensures that
the libc headers, that are copied from the specified header directory to
the sys-include directory, are used by libstdc++.

config, toplevel, Darwin: Pass -B instead of -L to C++ commands.
Darwin from 10.11 needs embedded rpaths to find the correct libraries at
runtime. Recent increases in hardening have made it such that the dynamic
loader will no longer fall back to using an installed libstdc++ when the
(new) linked one is not found. This means we fail configure tests (that
should pass) for runtimes that use C++.
We can resolve this by passing '-B' to the C++ command lines instead of '-L'
(-B implies -L on Darwin, but also causes a corresponding embedded rpath).

GCN, nvptx: Don't default-disable libstdc++ build
In addition to making libstdc++ itself available, this, via enabling
'build-gcc/*/libstdc++-v3/scripts/testsuite_flags', in particular also makes
the standard C++ headers available to 'make check-gcc-c++'. With that, there
are a lot of FAIL/UNRESOLVED -> PASS progressions, where we previously ran
into, for example:
FAIL: g++.dg/coroutines/co-await-syntax-00-needs-expr.C (test for errors, line 6)
FAIL: g++.dg/coroutines/co-await-syntax-00-needs-expr.C (test for excess errors)
Excess errors:
[...]/gcc/testsuite/g++.dg/coroutines/coro.h:132:10: fatal error: cstdlib: No such file or directory
Similarly, there are a lot of FAIL/UNRESOLVED -> UNSUPPORTED "progressions" due
to 'sorry, unimplemented: exception handling not supported'.
The 'make check-target-libstdc++-v3' results don't look too bad, either.
This also reverts Subversion r221362
(Git commit d94fae044da071381b73a2ee8afa874b14fa3820) "No libstdc++ for nvptx",
and commit 2f4f3c0e9345805160ecacd6de527b519a8c9206 "No libstdc++ for GCN".
With libstdc++ now available, libgrust gets enabled, which we in turn again
have to disable, for 'sorry, unimplemented: exception handling not supported'
reasons.

cobol: Fix up libgcobol configure [PR119216]
Sorry, seems I've screwed up the earlier libgcobol/configure.tgt change.
Looking in more detail, the way e.g. libsanitizer/configure.tgt works is
that it is sourced twice, once at toplevel and there it just sets
UNSUPPORTED=1 for fully unsupported triplets, and then inside of
libsanitizer/configure where it decides to include or not include the
various sublibraries depending on the *_SUPPORTED flags.
So, the following patch attempts to do the same for libgcobol as well.
The BIULD_LIBGCOBOL automake conditional was unused, this patch guards it
on LIBGCOBOL_SUPPORTED as well and guards with it
toolexeclib_LTLIBRARIES = libgcobol.la
Also, AM_CFLAGS has been changed to AM_CXXFLAGS as there are just C++
sources in the library.

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).

[Sending to binutils, gdb-patches and gcc-patches, since it touches the

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.

Support the PGO build for binutils+gdb
"autogen Makefile.def" showed no changes in Makefile.in.
PR binutils/26766
* Makefile.tpl (PGO_BUILD_TRAINING_FLAGS_TO_PASS): Add
PGO_BUILD_TRAINING=yes.
(PGO_BUILD_TRAINING_MFLAGS): New.
(all): Pass $(PGO_BUILD_TRAINING_MFLAGS) to the PGO build.
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.

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.
