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.

Move std::filesystem directory iterators and operations from
libstdc++fs.a to main libstdc++ library. These components have many
dependencies on OS support, which is not available on all targets. Some
additional autoconf checks and conditional compilation is needed to
ensure the files will build for all targets. Previously this code was
not compiled without --enable-libstdcxx-filesystem-ts but the C++17
components should be available for all hosted builds.
The tests for these components no longer need to link to libstdc++fs.a,
but are not expected to pass on all targets. To avoid numerous failures
on targets which are not expected to pass the tests (due to missing OS
functionality) leave the dg-require-filesystem-ts directives in place
for now. This will ensure the tests only run for builds where the
filesystem-ts library is built, which presumably means some level of OS

The previous patch for PR 87431 assumed that initialing a scalar type
could not throw, but it can obtain its value via a conversion operator,
which could throw. This meant the variant could get into a valueless
state, but the valueless_by_exception() member function would always
return false.
This patch fixes it by changing the emplace members to have strong
exception safety when initializing a contained value of trivially
copyable type. The _M_valid() member gets a corresponding change to
always return true for trivially copyable types, not just scalar types.
Strong exception safety (i.e. never becoming valueless) is achieved by
only replacing the current contained value once any potentially throwing
operations have completed. If constructing the new contained value can
throw then a new std::variant object is constructed to hold it, and then
move-assigned to *this (which won't throw).

Using path::_List::erase(const_iterator) to remove a non-final component
in path::lexically_normal() is a bug, because it leaves the following
component with an incorrect _M_pos value.
Instead of providing erase members that allow removing components from
the middle, replace them with pop_back() and
_M_erase_from(const_iterator) which only allow removing elements at the
end. Most uses of erase are unaffected, because they only remove
elements from the end anyway. The one use of erasure from the middle in
lexically_normal() is replaced by calls to pop_back() and/or clearing
the last component to leave it as an empty final filename.

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.

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.

Make the munge_options function round the largest_required_pool_block
value to a multiple of the smallest pool size (currently 8 bytes) to
avoid pools with odd sizes.
Ensure there is a pool large enough for blocks of the requested size.
Previously when largest_required_pool_block was exactly equal to one of
the pool_sizes[] values there would be no pool of that size. This patch
increases _M_npools by one, so there is a pool at least as large as the
requested value. It also reduces the size of the largest pool to be no

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.

The introduction of the empty __pair_base base class for PR 86751
changed the layout of std::pair<std::pair<...>, ...>. The outer pair and
its first member both have a base class of the same type, which cannot
exist at the same address. This causes the first member to be at a
non-zero offset.
The solution is to make the base class depend on the template
parameters, so that each pair type has a different base class type,
which allows the base classes of the outer pair and its first member to
have the same address.

Previously the _M_Nb member was incremented before calling
_M_unchecked_set which meant that the bit being set was out of bounds.
It either set the wrong bit in an allocated word, or accessed beyond the
end of the allocated memory in the _M_w vector. The fix for the bug is
to update the _M_Nb member after using it as an index.
As an optimisation, when a new block needs to be appended the call to
_M_unchecked_set can be avoided by appending a block with the least
significant bit already set to the desired value.

In the C++ FE, after emitting various errors about unrecognized names,
the parser can call
suggest_alternatives_for
and/or
suggest_alternative_in_explicit_scope.
These can issue zero or more suggestions for the unrecognized name,
or various other "note" diagnostics suggesting how to fix the problem.
For example, currently g++ emits:
t.cc:12:3: error: 'gtk_widget_showall' was not declared in this scope
12 | gtk_widget_showall (w);
| ^~~~~~~~~~~~~~~~~~
t.cc:12:3: note: suggested alternative: 'gtk_widget_show_all'
12 | gtk_widget_showall (w);
| ^~~~~~~~~~~~~~~~~~
| gtk_widget_show_all
This patch consolidates the common case when there is a single
candidate, so that the error can issue a fix-it hint directly.
This simplifies the above to:
t.cc:12:3: error: 'gtk_widget_showall' was not declared in this scope;
did you mean 'gtk_widget_show_all'?
12 | gtk_widget_showall (w);
| ^~~~~~~~~~~~~~~~~~
| gtk_widget_show_all
omitting the second "note" diagnostic.
Doing so requires changing the above "suggest_" functions so that
rather than being called after "error" and emitting a note directly,
they are called before the "error", and return a name_hint, which
can contain a suggestion and/or a deferred diagnostic. The "single
candidate" case is handled via a suggestion, and the "multiple
candidates" case via a new subclass of deferred_diagnostic.
There was some complication due to the fact that we don't always have
enough location information to issue a fix-it hint. Specifically,
for the case in qualified_name_lookup_error, the location is that of
the name, but the location of the qualifier prefix isn't reliably
available. For some hints, e.g. spell-corrections, the replacement
is of the name, and for others, e.g. parent namespaces, it's for the
qualified name. The patch addresses this by splitting this case out
into a new "suggest_alternatives_in_other_namespaces" function, for
which fix-it hints aren't issued.
Another complication is that of emitting a note when
--param cxx-max-namespaces-for-diagnostic-help
is reached. The patch emulates the existing behavior by emitting
the note from a deferred_diagnostic. This potentially needs to
co-exist with another deferred_diagnostic, so it works as a decorator
around any other such deferred_diagnostic. Doing so requires slightly
extending class name_hint.
On adding test coverage for the various cases, I discovered that
after emitting a "FOO is not a namespace-name" error, we also emit
a "expected namespace-name before" error. The patch removes this
second error for the case where it's redundant, simplifying this case
from e.g.:
spellcheck-ns.C:10:24: error: 'inner_ms' is not a namespace-name
10 | using namespace outer::inner_ms;
| ^~~~~~~~
spellcheck-ns.C:10:24: note: suggested alternative: 'inner_ns'
10 | using namespace outer::inner_ms;
| ^~~~~~~~
| inner_ns
spellcheck-ns.C:10:32: error: expected namespace-name before ';' token
10 | using namespace outer::inner_ms;
| ^
to:
spellcheck-ns.C:10:24: error: 'inner_ms' is not a namespace-name;
did you mean 'inner_ns'?
10 | using namespace outer::inner_ms;
| ^~~~~~~~
| inner_ns

The move constructor for the SSO string uses assign(const basic_string&)
when either:
(1) the source string is "local" and so the contents of the small string
buffer need to be copied, or
(2) the allocator does not propagate and is_always_equal is false.
Case (1) is suboptimal, because the assign member is not noexcept and
the compiler isn't smart enough to see it won't actually throw in this
case. This causes extra code in the move assignment operator so that any
exception will be turned into a call to std::terminate. This can be
fixed by copying small strings inline instead of calling assign.
Case (2) is a bug, because the specific instances of the allocators
could be equal even if is_always_equal is false. This can result in an
unnecessary deep copy (and potentially-throwing allocation) when the
storage should be moved. This can be fixed by simply checking if the
allocators are equal.

As a GNU extension we allow containers to be instantiated with

automatically rebind the allocator to the correct type. This extension
is disabled in strict modes (when __STRICT_ANSI__ is defined, i.e.

extension and so fail for strict modes.

Use the value of the first element as the initial value of the
__valarray_sum accumulator. Value-initialization might not create the
additive identity for the value type.
Make a similar change to __valarray_product even though it's only ever
used internally with a value_type of size_t.
