libstdc++: Use gnu_inline attribute on constexpr exception methods [PR123183]
As mentioned in https://gcc.gnu.org/pipermail/gcc-patches/2026-January/704712.html in the gnu::constexpr_only thread, gnu::gnu_inline attribute actually seems to work for most of what we need for C++26 constexpr exceptions (i.e. when we want out of line bodies for C++ < 26 and need to use constexpr for C++26, yet don't want for reasons mentioned in those two PRs the bodies of those constexpr methods to be emitted inline). Unfortunately clang++ doesn't handle it 100% properly and requires the redundant inline keyword to make it work (even when the methods are constexpr and thus implicilty inline), g++ doesn't require that, so the patch adds also the redundant inline keywords and not just the [[__gnu__::__gnu_inline__]] attribute. This way if something wants to inline those functions it can, but if their address is taken, we just rely on libstdc++.{so,a} to provide those (which it does as before because those TUs are compiled with older -std= modes). The earlier r16-6477-gd5743234731 commit made sure gnu::gnu_inline constexpr virtual methods can be key methods, so vtables and rtti can be emitted only in the TU defining non-gnu_inline versions of those. 2026-01-07 Jakub Jelinek <jakub@redhat.com> PR libstdc++/123183 PR libstdc++/123326 * libsupc++/exception (std::bad_exception::~bad_exception(), std::bad_exception::what()): Add inline keyword and [[__gnu__::__gnu_inline__]] attribute to the C++26 constexpr exceptions definitions. * libsupc++/exception.h (std::exception::~exception(), std::exception::what()): Likewise. * libsupc++/exception_ptr.h (std::exception_ptr::exception_ptr(void*)): Likewise. * libsupc++/nested_exception.h (std::nested_exception::~nested_exception()): Likewise. * libsupc++/typeinfo (std::bad_cast::~bad_cast(), std::bad_cast::what(), std::bad_typeid::~bad_typeid(), std::bad_typeid::what()): Likewise. * include/bits/new_except.h (std::bad_alloc::~bad_alloc(), std::bad_alloc::what(), std::bad_array_new_length::~bad_array_new_length(), std::bad_array_new_length::what()): Likewise. * include/bits/stdexcept_except.h (std::logic_error::logic_error(const string&), std::logic_error::logic_error(const char*), std::logic_error::~logic_error(), std::logic_error::what(), std::domain_error::domain_error(const string&), std::domain_error::domain_error(const char*), std::invalid_argument::invalid_argument(const string&), std::invalid_argument::invalid_argument(const char*), std::length_error::length_error(const string&), std::length_error::length_error(const char*), std::out_of_range::out_of_range(const string&), std::out_of_range::out_of_range(const char*), std::runtime_error::runtime_error(const string&), std::runtime_error::runtime_error(const char*), std::runtime_error::~runtime_error(), std::runtime_error::what(), std::overflow_error::overflow_error(const string&), std::overflow_error::overflow_error(const char*), std::overflow_error::~overflow_error(), std::underflow_error::underflow_error(const string&), std::underflow_error::underflow_error(const char*), std::underflow_error::~underflow_error()): Likewise.

libstdc++: Correct value of __cpp_lib_constexpr_exceptions [PR117785]
Only P3068R6 (Allowing exception throwing in constant-evaluation) is implemented in the library so far, so the value of the constexpr_exceptions feature test macro should be 202411L. Once we support the library changes in P3378R2 (constexpr exception types) then we can set the value to 202502L again. libstdc++-v3/ChangeLog: PR libstdc++/117785 * include/bits/version.def (constexpr_exceptions): Define correct value. * include/bits/version.h: Regenerate. * libsupc++/exception: Check correct value. * testsuite/18_support/exception/version.cc: New test. |

c++, libstdc++: Implement C++26 P3068R5 - constexpr exceptions [PR117785]
The following patch implements the C++26 P3068R5 - constexpr exceptions
paper.
As the IL cxx_eval_constant* functions process already contains the low
level calls like __cxa_{allocate,free}_exception, __cxa_{,re}throw etc.,
the patch just makes 10 extern "C" __cxa_* functions magic builtins which
during constant evaluation pretend to be constexpr even when not declared
so and handle them directly, plus does the same for 3 std namespace
functions - std::uncaught_exceptions, std::current_exception and
std::rethrow_exception and adds one new FE builtin -
__builtin_eh_ptr_adjust_ref which the library can use instead of the
_M_addref and _M_release out of line methods (this one instead of
recognizing _M_* as magic too because those are clearly specific to
libstdc++ and e.g. libc++ could use something else).
The patch uses magic VAR_DECLs with heap_{uninit_,,deleted_}identifier
DECL_NAME like for operator new/delete for objects allocated with
__cxa_allocate_exception, just sets their DECL_LANG_SPECIFIC so that
we can track their reference count as well (with std::exception_ptr
the same exception object can be referenced multiple times and we want
to destruct and free only when it reaches zero refcount).
For uncaught exceptions being propagated, the patch uses new kind of
*jump_target, which is that magic VAR_DECL described above.
The largest change in the patch is making jump_target argument non-optional
in cxa_eval_constant_exception and all functions it calls that need it.
This is because exceptions can be thrown from pretty much everywhere, e.g.
binary expression can throw in either operand. And the patch also adds
if (*jump_target) return NULL_TREE; or similar in many spots, so that we
don't crash because cxx_eval_constant_expression returned NULL_TREE
somewhere before actually trying to use it and so that we don't uselessly
dive into other operands etc.
Note, with statement expressions actually this was something we just didn't
handle correctly before, one can validly have:
a = ({ if (x) return 42; 12; }) + b;
or in the other operand, or break/continue instead of return if it is
somewhere in a loop/switch; and it isn't ok to branch from one operand to
another one through some kind of goto.
On the potential_constant_expression_1 side, important change was to
set *jump_target conservatively on calls that could throw for C++26 (the
patch uses magic void_node for potential_constant_expression* instead of
VAR_DECL, so that we don't have to create new VAR_DECLs there uselessly).
Without that change, several methods in libstdc++ wouldn't work correctly.
I'm not sure what exactly potential_constant_expression_1 maps to in the
C++26 standard wording now and whether doing that is ok, because basically
after the first call to non-noexcept function it stops checking stuff.
And, in some spots where I know potential_constant_expression_1 didn't
check some subexpressions (e.g. the EH only cleanups or TRY_BLOCK handlers)
I've added *potential_constant_expression* calls during cxx_eval_constant*,
not sure if I need to do that because potential_constant_expression_1 is
very conservative and just doesn't recurse on subexpressions in many cases.

libstdc++: #ifdef out #pragma GCC system_header
In r15-3714-gd3a7302ec5985a I added -Wsystem-headers to the libstdc++ build flags to help catch problems in the library. This patch takes a different approach, of disabling the #pragma system_header unless _GLIBCXX_SYSHDR is defined. As a result, the testsuites will treat them as non-system-headers to get better warning coverage during regression testing of both gcc and libstdc++, not just when building the library. My rationale for the #ifdef instead of just removing the #pragma is the three G++ tests that want to test libstdc++ system header behavior, so we need a way to select it. This doesn't affect installed libraries, as they get their system-header status from the lookup path. But testsuite_flags --build-includes gives -I directives rather than -isystem. This patch doesn't change the headers in config/ because I'm not compiling with most of them, so won't see any warnings that need fixing. Adjusting them could happen later, or we can not bother. libstdc++-v3/ChangeLog: * acinclude.m4 (WARN_FLAGS): Remove -Wsystem-headers. * configure: Regenerate. * include/bits/algorithmfwd.h: #ifdef

libstdc++: Deprecate std::unexpected and handler functions
These functions have been deprecated since C++11, and were removed in C++17. The proposal P0323 wants to reuse the name std::unexpected for a class template, so we will need to stop defining the current function for C++23 anyway. This marks them as deprecated for C++11 and up, to warn users they won't continue to be available. It disables them for C++17 and up, unless the _GLIBCXX_USE_DEPRECATED macro is defined. The <unwind-cxx.h> header uses std::unexpected_handler in the public API, but since that type is the same as std::terminate_handler we can just use that instead, to avoid warnings about it being deprecated. libstdc++-v3/ChangeLog: * doc/xml/manual/evolution.xml: Document deprecations. * doc/html/*: Regenerate. * libsupc++/exception (unexpected_handler, unexpected) (get_unexpected, set_unexpected): Add deprecated attribute.

libstdc++: Improvements to Doxygen markup
This attempst to improve the doxygen output to work around what seems to be some bugs in doxygen (issues 8635 and 8638). The @addtogroup command doesn't work for entities inside a nested namespace (see 8635) so we need to close and reopen groups on entering and elaving nested namespaces. This fixes the problem that chrono::duration and chrono::time_point were not documented in the "Time" documentation group. I am unable to make the path classes appear as part of their relevant groups (File System and Filesystem TS), nor the contents of <exception> or <system_error>. I have made some minor improvements to the docs for those types, including starting to address PR 97001 by adding @since to the doxygen comments. This change also excludes the <experimental/bits/net.h> header from Doxygen processing, so we don't get an unwanted "Networking-ts" group in the documentation. Signed-off-by: Jonathan Wakely <jwakely@redhat.com> libstdc++-v3/ChangeLog: * doc/doxygen/doxygroups.cc: Fix docs for std::literals. * doc/doxygen/user.cfg.in: Exclude the Networking TS header. Add some more predefined macros. * include/bits/fs_fwd.h: Move @addtogroup commands inside namespaces.
