68c2e9e923 libstdc++: Fix and simplify freestanding configuration [PR103866]
This fixes the --disable-hosted-libstdcxx build so that it works with
--without-headers. Currently you need to also use --with-newlib, which
is confusing for users who aren't actually using newlib.

The AM_PROG_LIBTOOL checks are currently skipped for --with-newlib and
--with-avrlibc builds, with this change they are also skipped when using
--without-headers.  It would be nice if using --disable-hosted-libstdcxx
automatically skipped those checks, but GLIBCXX_ENABLE_HOSTED comes too
late to make the AM_PROG_LIBTOOL checks depend on $is_hosted.

The checks for EOF, SEEK_CUR etc. cause the build to fail if there is no
<stdio.h> available.  Unlike most headers, which get a HAVE_FOO_H macro,
<stdio.h> is in autoconf's default includes, so every check tries to
include it unconditionally. This change skips those checks for
freestanding builds.

Similarly, the checks for <stdint.h> types done by GCC_HEADER_STDINT try
to include <stdio.h> and fail for --without-headers builds. This change
skips the use of GCC_HEADER_STDINT for freestanding. We can probably
stop using GCC_HEADER_STDINT entirely, since only one file uses the
gstdint.h header that is generated, and that could easily be changed to
use <stdint.h> instead. That can wait for stage 1.

We also need to skip the GLIBCXX_CROSSCONFIG stage if --without-headers
was used, since we don't have any of the functions it deals with.

The end result of the changes above is that it should not be necessary
for a --disable-hosted-libstdcxx --without-headers build to also use
--with-newlib.

Finally, compile libsupc++ with -ffreestanding when --without-headers is
used, so that <stdint.h> will use <gcc-stdint.h> instead of expecting it
to come from libc.

a634928f5c libstdc++: Fix pretty printing of std::unique_ptr [PR103086]
Since std::tuple started using [[no_unique_address]] the tuple<T*, D>
member of std::unique_ptr<T, D> has two _M_head_impl subobjects, in
different base classes. That means this printer code is ambiguous:

    tuple_head_type = tuple_impl_type.fields()[1].type   # _Head_base
    head_field = tuple_head_type.fields()[0]
    if head_field.name == '_M_head_impl':
        self.pointer = tuple_member['_M_head_impl']

In older versions of GDB it happened to work by chance, because GDB
returned the last _M_head_impl member and std::tuple's base classes are
stored in reverse order, so the last one was the T* element of the
tuple. Since GDB 11 it returns the first _M_head_impl, which is the
deleter element.

The fix is for the printer to stop using an ambiguous field name and
cast the tuple to the correct base class before accessing the
_M_head_impl member.

Instead of fixing this in both UniquePointerPrinter and StdPathPrinter a
new unique_ptr_get function is defined to do it correctly. That is
defined in terms of new tuple_get and _tuple_impl_get functions.

It would be possible to reuse _tuple_impl_get to access each element in
StdTuplePrinter._iterator.__next__, but that already does the correct
casting, and wouldn't be much simpler anyway.

libstdc++-v3/ChangeLog:

	PR libstdc++/103086
	* python/libstdcxx/v6/printers.py (_tuple_impl_get): New helper
	for accessing the tuple element stored in a _Tuple_impl node.
	(tuple_get): New function for accessing a tuple element.
	(unique_ptr_get): New function for accessing a unique_ptr.
	(UniquePointerPrinter, StdPathPrinter): Use unique_ptr_get.
	* python/libstdcxx/v6/xmethods.py (UniquePtrGetWorker): Cast
	tuple to its base class before accessing _M_head_impl.

c883d1dcde libstdc++: Fix vector<bool> printer tests to work in debug mode
This fixes a compilation error in debug mode, due to std::_Bit_reference
not being defined, because it's in namespace std::__cxx1998 instead. We
can refer to it as vector<bool>::reference instead, which always works.

That fixes some compilation errors in debug mode, but the tests fail at
run-time instead because the printers for vector<bool> helpers are only
registered for the std namespace, not std::__cxx1998. That is fixed by
using add_container to register the printers instead of add_version, as
the former registers them in the std and std::__cxx1998 namespaces.

db853ff78a libstdc++: Install GDB pretty printers for debug library
The additional libraries installed by --enable-libstdcxx-debug are built
without optimization to aid debugging, but the Python pretty printers
are not installed alongside them. This means that you can step through
the unoptimized library code, but at the expense of pretty printing the
library types.

This remedies the situation by installing another copy of the GDB hooks
alongside the debug version of libstdc++.so.

c2fc1702cb libstdc++: Install libstdc++*-gdb.py more robustly [PR 99453]
In order for GDB to auto-load the pretty printers, they must be installed
as "libstdc++.$ext-gdb.py", where 'libstdc++.$ext' is the name of the
object file that is loaded by GDB [1], i.e. the libstdc++ shared library.

The approach taken in libstdc++-v3/python/Makefile.am is to loop over
files matching 'libstdc++*' in $(DESTDIR)$(toolexeclibdir) and choose
the last file matching that glob that is not a symlink, the Libtool
'*.la' file or a Python file.

That works fine for ELF targets where the matching names are:

  libstdc++.a
  libstdc++.so
  libstdc++.so.6
  libstdc++.so.6.0.29

But not for macOS with:

  libstdc++.6.dylib
  libstdc++.a

Or MinGW with:

  libstdc++-6.dll
  libstdc++.dll.a

Try to make a better job at installing the pretty printers with the
correct name by copying the approach taken by isl [2], that is, using
a sed invocation on the Libtool-generated 'libstdc++.la' to read the
correct name for the current platform.

9dacc828bf libstdc++: Fix find_type helper to work consistently
The find_type helper function sometimes results in "class X::name" and
lookup for that fails. For more details see "Problem 1" in
https://gcc.gnu.org/pipermail/libstdc++/2021-March/052132.html and the
example at https://sourceware.org/bugzilla/show_bug.cgi?id=27510#c2

This patch replaces typ.unqualified() with typ.tag, which is never
qualified, and will never include the 'class' or 'struct' keywords.
Using the .tag attribute should be safe here because we know we are
looking at a class type and we've already used strip_typedefs().

libstdc++-v3/ChangeLog:

	* python/libstdcxx/v6/printers.py (find_type): Use tag attribute
	instead of unqualified() method.

7c1e7eed89 libstdc++: Add C++ runtime support for new 128-bit long double format
This adds support for the new __ieee128 long double format on
powerpc64le targets.

Most of the complexity comes from wanting a single libstdc++.so library
that contains the symbols needed by code compiled with both
-mabi=ibmlongdouble and -mabi=ieeelongdouble (and not forgetting
-mlong-double-64 as well!)

In a few places this just requires an extra overload, for example
std::from_chars has to be overloaded for both forms of long double.
That can be done in a single translation unit that defines overloads
for 'long double' and also '__ieee128', so that user code including
<charconv> will be able to link to a definition for either type of long
double. Those are the easy cases.

The difficult parts are (as for the std::string ABI transition) the I/O
and locale facets. In order to be able to write either form of long
double to an ostream such as std::cout we need the locale to contain a
std::num_put facet that can handle both forms. The same approach is
taken as was already done for supporting 64-bit long double and 128-bit
long double: adding extra overloads of do_put to the facet class. On
targets where the new long double code is enabled, the facets that are
registered in the locale at program startup have additional overloads so
that they can work with any long double type. Where this fails to work
is if user code installs its own facet, which will probably not have the
additional overloads and so will only be able to output one or the other
type. In practice the number of users expecting to be able to use their
own locale facets in code using a mix of -mabi=ibmlongdouble and
-mabi=ieeelongdouble is probably close to zero.

Provide means, in the form of a `--with-toolexeclibdir=' configuration
option, to override the default installation directory for target
libraries, otherwise known as $toolexeclibdir.  This is so that it is
possible to get newly-built libraries, particularly the shared ones,
installed in a common place, so that they can be readily used by the
target system as their host libraries, possibly over NFS, without a need
to manually copy them over from the currently hardcoded location they
would otherwise be installed in.

In the presence of the `--enable-version-specific-runtime-libs' option
and for configurations building native GCC the option is ignored.

9d50a6a785 libstdc++:: improve how pretty printers find node types (PR 91997)
This fixes two related problems.

The iterators for node-based containers use nested typedefs such as
std::list<T>::iterator::_Node to denote their node types. As reported in
https://bugzilla.redhat.com/show_bug.cgi?id=1053438 those typedefs are
not always present in the debug info. That means the pretty printers
cannot find them using gdb.lookup_type (via the find_type helper).
Instead of looking up the nested typedefs this patch makes the printers
look up the actual class templates directly.

A related problem (and the original topic of PR 91997) is that GDB fails
to find types via gdb.lookup_type when printing a backtrace from a
non-C++ functiion: https://sourceware.org/bugzilla/show_bug.cgi?id=25234
That is also solved by not looking up the nested typedef.

a4395a846a PR libstdc++/89466 avoid slow xsltproc command in configure
Certain broken versions of xsltproc ignore the --nonet option and will
attempt to fetch the docbook stylesheet from the WWW when it isn't in
the local XML catalog.

This patch checks for the local stylesheet directory first, and doesn't
use xsltproc if no local stylesheets are found. Checking for the local
directory is done using xmlcatalog if available, only checking the
hardcoded list of directories if xmlcatalog fails. The right directory
for Suse is added to the hardcoded list.

This should avoid doing an xsltproc check that would need to download
the stylesheet, so no network connection is made even if a broken
xsltproc is present.

d942bc80e4 PR libstdc++/87855 fix optional for types with non-trivial copy/move
When the contained value is not trivially copy (or move) constructible
the union's copy (or move) constructor will be deleted, and so the
_Optional_payload delegating constructors are invalid. G++ fails to
diagnose this because it incorrectly performs copy elision in the
delegating constructors. Clang does diagnose it (llvm.org/PR40245).

The solution is to avoid performing any copy (or move) when the
contained value's copy (or move) constructor isn't trivial. Instead the
contained value can be constructed by calling _M_construct. This is OK,
because the relevant constructor doesn't need to be constexpr when the
contained value isn't trivially copy (or move) constructible.

Additionally, this patch removes a lot of code duplication in the
_Optional_payload partial specializations and the _Optional_base partial
specialization, by hoisting it into common base classes.

The Python pretty printer for std::optional needs to be adjusted to
support the new layout. Retain support for the old layout, and add a
test to verify that the support still works.

4f87bb8d6e PR libstdc++/71044 optimize std::filesystem::path construction
This new implementation has a smaller footprint than the previous
implementation, due to replacing std::vector<_Cmpt> with a custom pimpl
type that only needs a single pointer. The _M_type enumeration is also
combined with the pimpl type, by using a tagged pointer, reducing
sizeof(path) further still.

Construction and modification of paths is now done more efficiently, by
splitting the input into a stack-based buffer of string_view objects
instead of a dynamically-allocated vector containing strings. Once the
final size is known only a single allocation is needed to reserve space
for it.  The append and concat operations no longer require constructing
temporary path objects, nor re-parsing the entire native pathname.

This results in algorithmic improvements to path construction, and
working with large paths is much faster.

11aa881f98 PR libstdc++/87308 adjust regex used in std::any pretty printer
The pretty printer for std::any fails when the contained value is a
locally-defined type, because the name in the debuginfo has
cv-qualifiers and ptr-declarators in different positions. The unexpected
format confuses the printer. This makes the printer's regex handle
either format.

This isn't a complete fix because looking up the contained type fails
when there are two types with the same name (defined in different local
scopes). This applies to all closure types defined in a given function,
as they all appear as "func()::lambda" in the debuginfo names.

22e0527251 Update GCC to autoconf 2.69, automake 1.15.1 (PR bootstrap/82856).
This patch updates GCC to use autoconf 2.69 and automake 1.15.1.
(That's not the latest automake version, but it's the one used by
binutils-gdb, with which consistency is desirable, and in any case
seems a useful incremental update that should make a future update to
1.16.1 easier.)

The changes are generally similar to the binutils-gdb ones, and are
copied from there where shared files and directories are involved
(there are some further changes to such shared directories, however,
which I'd expect to apply to binutils-gdb once this patch is in GCC).
Largely, obsolete AC_PREREQ calls are removed, while many
AC_LANG_SOURCE calls are added to avoid warnings from aclocal and
autoconf.  Multilib support is no longer included in core automake,
meaning that multilib.am needs copying from automake's contrib
directory into the GCC source tree.  Autoconf 2.69 has Go support, so
local copies of that support are removed.  I hope the D support will
soon be submitted to upstream autoconf so the local copy of that can
be removed in a future update.  Changes to how automake generates
runtest calls mean quotes are removed from RUNTEST definitions in five
lib*/testsuite/Makefile.am files (libatomic, libgomp, libitm,
libphobos, libvtv; some others have RUNTEST definitions without
quotes, which are still OK); libgo and libphobos also get
-Wno-override added to AM_INIT_AUTOMAKE so those overrides of RUNTEST
do not generate automake warnings.

Note that the regeneration did not include regeneration of
fixincludes/config.h.in (attempting such regeneration resulted in all
the USED_FOR_TARGET conditionals disappearing; and I don't see
anything in the fixincludes/ directory that would result in such
conditionals being generated, unlike in the gcc/ directory).  Also
note that libvtv/testsuite/other-tests/Makefile.in was not
regenerated; that directory is not listed as a subdirectory for which
Makefile.in gets regenerated by calling "automake" in libvtv/, so I'm
not sure how it's meant to be regenerated.

While I mostly fixed warnings should running aclocal / automake /
autoconf, there were various such warnings from automake in the
libgfortran, libgo, libgomp, liboffloadmic, libsanitizer, libphobos
directories that I did not fix, preferring to leave those to the
relevant subsystem maintainers.  Specifically, most of those warnings
were of the following form (example from libgfortran):

Makefile.am:48: warning: source file 'caf/single.c' is in a subdirectory,
Makefile.am:48: but option 'subdir-objects' is disabled
automake: warning: possible forward-incompatibility.
automake: At least a source file is in a subdirectory, but the 'subdir-objects'
automake: automake option hasn't been enabled.  For now, the corresponding output
automake: object file(s) will be placed in the top-level directory.  However,
automake: this behaviour will change in future Automake versions: they
will
automake: unconditionally cause object files to be placed in the same subdirectory
automake: of the corresponding sources.
automake: You are advised to start using 'subdir-objects' option throughout your
automake: project, to avoid future incompatibilities.

I think it's best for the relevant maintainers to add subdir-objects
and do any other associated Makefile.am changes needed.  In some cases
the paths in the warnings involved ../; I don't know if that adds any
extra complications to the use of subdir-objects.

I've tested this with native, cross and Canadian cross builds.  The
risk of any OS-specific issues should I hope be rather lower than if a
libtool upgrade were included (we *should* do such an upgrade at some
point, but it's more complicated - it involves identifying all our
local libtool changes to see if any aren't included in the upstream
version we update to, and reverting an upstream libtool patch that's
inappropriate for use in GCC); I think it would be better to get this
update into GCC so that people can test in different configurations
and we can fix any issues found, rather than to try to get more and
more testing done before it goes in.

33b43b0d8c Define std::string and related typedefs outside __cxx11 namespace
The typedefs for common specializations of std::__cxx11::basic_string do
not need to be in the std::__cxx11 namespace. Those typedefs are never
used for linkage purposes so don't appear in mangled names, and so don't
need to be distinct from the equivalent typedefs for the COW
std::basic_string specializations. It is OK for the same typedef to
refer to different types in different translation units.

Defining them directly in namespace std improves diagnostics that use
those typedefs. For example:

error: could not convert '1' from 'int' to 'std::__cxx11::string' {aka 'std::__cxx11::basic_string<char>'}

will now be printed as:

error: could not convert '1' from 'int' to 'std::string' {aka 'std::__cxx11::basic_string<char>'}

The precise type is still shown, but the typedef is not obfuscated with
the inline namespace.

Use -Wabi=2 to fix warnings about -Wabi having no effect on its own.
This requires suppressing two warnings in src/c++11/debug.cc which do
not affect the library ABI.

Previously libstdc++ defaulted to --enable-werror but the -Werror flag
was not actually added unless --enable-maintainer-mode was used. This is
not documented and not the expected behaviour. This removes any special

	(add_one_type_printer): Prepend namespace to match argument.
	(register_type_printers): Add type printers for char16_t and char32_t
	string types and for types using cxx11 ABI. Update calls to
	add_one_template_type_printer to provide default argument dicts.
	* testsuite/libstdc++-prettyprinters/80276.cc: New test.
	* testsuite/libstdc++-prettyprinters/whatis.cc: Remove tests for
	basic_string<unsigned char> and basic_string<signed char>.
	* testsuite/libstdc++-prettyprinters/whatis2.cc: Duplicate whatis.cc
	to test local variables, without overriding _GLIBCXX_USE_CXX11_ABI.
