    [testsuite] conditionalize dg-additional-sources on target and type

added two additional args to dg-additional-files-options.
Unfortunately, this completely broke several testsuites like

ERROR: tcl error sourcing /vol/gcc/src/hg/master/local/libatomic/testsuite/../../gcc/testsuite/lib/gcc-dg.exp.
wrong # args: should be "dg-additional-files-options options source dest type"

since the patch forgot to adjust some of the callers.

This patch fixes that.

Tested on i386-pc-solaris2.11, sparc-sun-solaris2.11, and
x86_64-pc-linux-gnu.

Like in r12-7519-g027e30414492d50feb2854aff38227b14300dc4b, I've done
git grep -v 'long long\|optab optab\|template template\|double double' | grep ' \([a-zA-Z]\+\) \1 '

This is just part of the changes, mostly for non-gcc directories.
I'll try to get to the rest soon.  Obviously, the above command also
finds cases which are correct as is and shouldn't be changed, so one
needs to manually inspect everything.

I'd hope most of it is pretty obvious, but the config/ and libstdc++-v3/
hunks include a tweak in a license wording, though other copies of the
similar license have the wording right.

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).

ChangeLog:

	* configure: Regenerate.
	* configure.ac: Do not add default runpaths to GCC exes
	when we are building -static-libstdc++/-static-libgcc (the
	default).
	* libtool.m4: Add 'enable-darwin-at-runpath'.  Act  on the
	enable flag to alter Darwin libraries to use @rpath names.

My previous nm patch handled all cases but one -- if the user set NM in
the environment to a path which contained an option, libtool's nm
detection tries to run nm against a copy of nm with the options in it:
e.g. if NM was set to "nm --blargle", and nm was found in /usr/bin, the
test would try to run "/usr/bin/nm --blargle /usr/bin/nm --blargle".
This is unlikely to be desirable: in this case we should run
"/usr/bin/nm --blargle /usr/bin/nm".

Furthermore, as part of this nm has to detect when the passed-in $NM
contains a path, and in that case avoid doing a path search itself.
This too was thrown off if an option contained something that looked
like a path, e.g. NM="nm -B../prev-gcc"; libtool then tries to run
"nm -B../prev-gcc nm" which rarely works well (and indeed it looks
to see whether that nm exists, finds it doesn't, and wrongly concludes
that nm -p or whatever does not work).

Fix all of these by clipping all options (defined as everything
including and after the first " -") before deciding whether nm
contains a path (but not using the clipped value for anything else),
and then removing all options from the path-modified nm before
looking to see whether that nm existed.

NM=my-nm now does a path search and runs e.g.
  /usr/bin/my-nm -B /usr/bin/my-nm

NM=/usr/bin/my-nm now avoids a path search and runs e.g.
  /usr/bin/my-nm -B /usr/bin/my-nm

NM="my-nm -p../wombat" now does a path search and runs e.g.
  /usr/bin/my-nm -p../wombat -B /usr/bin/my-nm

NM="../prev-binutils/new-nm -B../prev-gcc" now avoids a path search:
  ../prev-binutils/my-nm -B../prev-gcc -B ../prev-binutils/my-nm

This seems to be all combinations, including those used by GCC bootstrap
(which, before this commit, fails to bootstrap when configured
--with-build-config=bootstrap-lto, because the lto plugin is now using
--export-symbols-regex, which requires libtool to find a working nm,
while also using -B../prev-gcc to point at the lto plugin associated
with the GCC just built.)

Regenerate all affected configure scripts.

Libtool needs to get BSD-format (or MS-format) output out of the system
nm, so that it can scan generated object files for symbol names for
-export-symbols-regex support.  Some nms need specific flags to turn on
BSD-formatted output, so libtool checks for this in its AC_PATH_NM.
Unfortunately the code to do this has a pair of interlocking flaws:

 - it runs the test by doing an nm of /dev/null.  Some platforms
   reasonably refuse to do an nm on a device file, but before now this
   has only been worked around by assuming that the error message has a
   specific textual form emitted by Tru64 nm, and that getting this
   error means this is Tru64 nm and that nm -B would work to produce
   BSD-format output, even though the test never actually got anything
   but an error message out of nm -B.  This is fixable by nm'ing *nm
   itself* (since we necessarily have a path to it).

 - the test is entirely skipped if NM is set in the environment, on the
   grounds that the user has overridden the test: but the user cannot
   reasonably be expected to know that libtool wants not only nm but
   also flags forcing BSD-format output.  Worse yet, one such "user" is
   the top-level Cygnus configure script, which neither tests for
   nor specifies any BSD-format flags.  So platforms needing BSD-format
   flags always fail to set them when run in a Cygnus tree, breaking
   -export-symbols-regex on such platforms.  Libtool also needs to
   augment $LD on some platforms, but this is done unconditionally,
   augmenting whatever the user specified: the nm check should do the
   same.

   One wrinkle: if the user has overridden $NM, a path might have been
   provided: so we use the user-specified path if there was one, and
   otherwise do the path search as usual.  (If the nm specified doesn't
   work, this might lead to a few extra pointless path searches -- but
   the test is going to fail anyway, so that's not a problem.)

(Tested with NM unset, and set to nm, /usr/bin/nm, my-nm where my-nm is a
symlink to /usr/bin/nm on the PATH, and /not-on-the-path/my-nm where
*that* is a symlink to /usr/bin/nm.)

ChangeLog:

	* libtool.m4 (LT_PATH_NM): Try BSDization flags with a user-provided
	NM, if there is one.  Run nm on itself, not on /dev/null, to avoid
	errors from nms that refuse to work on non-regular files.  Remove
	other workarounds for this problem.  Strip out blank lines from the
	nm output.

Recently, mingw-w64 has got updated <msxml.h> from Wine which is included
indirectly by <windows.h> if `WIN32_LEAN_AND_MEAN` is not defined. The
`IXMLDOMDocument` class has a member function named `abort()`, which gets
affected by our `abort()` macro in "system.h".

`WIN32_LEAN_AND_MEAN` should, nevertheless, always be defined. This
can exclude 'APIs such as Cryptography, DDE, RPC, Shell, and Windows
Sockets' [1], and speed up compilation of these files a bit.

This change adds the configury bits to activate the build of
shared libs on VxWorks ports configured with --enable-shared,
for libraries variants where this is generally supported (rtp,
code model !large - currently not compatible with -fPIC).

Set lt_cv_deplibs_check_method in libtool.m4, so the build of
libraries know how to establish dependencies.  This is useful in
configurations such as aarch64 where proper support of LSE relies
on accurate dependency information between libstdc++ and libgcc_s
to begin with.

Regenerate configure scripts to reflect libtool.m4 change.

2022-10-09  Olivier Hainque  <hainque@adacore.com>

	* libtool.m4 (*vxworks*): When enable_shared, set dynamic_linker
	and friends for rtp !large. Assume the linker has the required
	abilities and set lt_cv_deplibs_check_method.

gcc/
	* config.gcc (*vxworks*): Add t-slibgcc fragment
	if enable_shared.

libgcc/
	* config.host (*vxworks*): When enable_shared, add
	libgcc and crtstuff "shared" fragments for rtp except
	large code model.
	(aarch64*-wrs-vxworks7*): Remove t-slibgcc-libgcc from
	the list of fragments.

The change in major version (and the increment from Darwin19 to 20)
caused libtool tests to fail which resulted in incorrect build settings
for shared libraries.

We take this opportunity to sort out the shared undefined symbols state
rather than propagating the current unsound behaviour into a new rev.

This change means that we default to the case that missing symbols are
considered an error, and if one wants to allow this intentionally, the
confiuration for that case should be set appropriately.

Three existing cases need undefined dynamic lookup:
 libitm, where there is already a configuration mechanism to add the
         flags.
 libcc1, where we add simple configuration to add the flags for Darwin.
 libsanitizer, where we can add to the existing extra flags.

	PR target/97865
