dnl GLIBCXX_CONDITIONAL (NAME, SHELL-TEST)

dnl Exactly like AM_CONDITIONAL, but delays evaluation of the test until the
dnl end of configure. This lets tested variables be reassigned, and the
dnl conditional will depend on the final state of the variable. For a simple
dnl example of why this is needed, see GLIBCXX_ENABLE_HOSTED.

used elsewhere in this file.
(GLIBCXX_EVALUATE_CONDITIONALS): New macro...
* configure.ac: ...called here to expand all conditionals.
* Makefile.am: Conditionalize SUBDIRS on GLIBCXX_HOSTED.
* include/Makefile.am: Remove redundant gxx_include_dir assignment.
(install-freestanding-headers): New target, a subset of
install-headers. Conditionalize install-data-local on GLIBCXX_HOSTED.

Commit the vtable verification feature.
Commit the vtable verification feature. This feature is designed to
detect, at run time, if/when the vtable pointer in a C++ object has
been corrupted, before allowing virtual calls through that pointer.
If pointer corruption is detected, execution of the program is halted.

Commit the vtable verification feature.
Commit the vtable verification feature. This feature is designed to
detect, at run time, if/when the vtable pointer in a C++ object has
been corrupted, before allowing virtual calls through that pointer.
If pointer corruption is detected, execution of the program is halted.

Commit the vtable verification feature. This feature is designed to
detect, at run time, if/when the vtable pointer in a C++ object has
been corrupted, before allowing virtual calls through that pointer.
If pointer corruption is detected, execution of the program is halted.

PR libstdc++/67843 set shared_ptr lock policy at build-time
This resolves a longstanding issue where the lock policy for shared_ptr
reference counting depends on compilation options when the header is
included, so that different -march options can cause ABI changes. For
example, objects compiled with -march=armv7 will use atomics to
synchronize reference counts, and objects compiled with -march=armv5t
will use a mutex. That means the shared_ptr control block will have a
different layout in different objects, causing ODR violations and
undefined behaviour. This was the root cause of PR libstdc++/42734 as
well as PR libstdc++/67843.
The solution is to decide on the lock policy at build time, when
libstdc++ is configured. The configure script checks for the
availability of the necessary atomic built-ins for the target and fixes
that choice permanently. Different -march flags used to compile user
code will not cause changes to the lock policy. This results in an ABI
change for certain compilations, but only where there was already an ABI
incompatibility between the libstdc++.so library and objects built with
an incompatible -march option. In general, this means a more stable ABI
that isn't silently altered when -march flags make addition atomic ops
available.
To force a target to use "atomic" or "mutex" the new configure option
--with-libstdcxx-lock-policy can be used.
In order to turn ODR violations into linker errors, the uses of
shared_ptr in filesystem directory iterators have been replaced
with __shared_ptr, and explicit instantiations are declared. This
ensures that object files using those types cannot link to libstdc++
libs unless they use the same lock policy.

# For libtool versioning info, format is CURRENT:REVISION:AGE
libstdc++: Add std::from_chars for floating-point types
This adds the missing std::from_chars overloads for floating-point
types, as required for C++17 conformance.
The implementation is a hack and not intended to be used in the long
term. Rather than parsing the string directly, this determines the
initial portion of the string that matches the pattern determined by the
chars_format parameter, then creates a NTBS to be parsed by strtod (or
strtold or strtof).
Because creating a NTBS requires allocating memory, but std::from_chars
is noexcept, we need to be careful to minimise allocation. Even after
being careful, allocation failure is still possible, and so a
non-conforming std::no_more_memory error code might be returned.
Because strtod et al depend on the current locale, but std::from_chars
does not, we change the current thread's locale to "C" using newlocale
and uselocale before calling strtod, and restore it afterwards.
Because strtod doesn't have the equivalent of a std::chars_format
parameter, it has to examine the input to determine the format in use,
even though the std::from_chars code has already parsed it once (or
twice for large input strings!)
By replacing the use of strtod we could avoid allocation, avoid changing
locale, and use optimised code paths specific to each std::chars_format
case. We would also get more portable behaviour, rather than depending
on the presence of uselocale, and on any bugs or quirks of the target
libc's strtod. Replacing strtod is a project for a later date.

PR libstdc++/86756 Move rest of std::filesystem to libstdc++.so
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
support is present.
