Patrick Palka	ac1a399bf6	libstdc++: Implement C++23 std::bind_back from P2387R3 [PR108827] ... The implementation is based off of std::bind_front. Since this is a C++23 feature we use deducing this unconditionally. PR libstdc++/108827 PR libstdc++/111327 libstdc++-v3/ChangeLog: * include/bits/version.def (bind_back): Define. * include/bits/version.h: Regenerate. * include/std/functional (_Bind_back): Define for C++23. (bind_back): Likewise. * testsuite/20_util/function_objects/bind_back/1.cc: New test (adapted from corresponding bind_front test). * testsuite/20_util/function_objects/bind_back/111327.cc: Likewise.	2024-01-12 23:02:12 -05:00
Patrick Palka	3e1ffa7dd1	libstdc++: Use C++23 deducing this in std::bind_front ... This simplifies the operator() of _Bind_front using C++23 deducing this, allowing us to condense multiple operator() overloads into one. In passing I think we can remove _Bind_front's defaulted special member declarations and just let the compiler implicitly generate them for us. libstdc++-v3/ChangeLog: * include/std/functional (_Bind_front): Remove =default special member function declarations. (_Bind_front::operator()): Implement using C++23 deducing this when available. * testsuite/20_util/function_objects/bind_front/111327.cc: Adjust testcase to expect better errors in C++23 mode.	2024-01-12 22:55:43 -05:00

Jonathan Wakely	f4ab68469c	libstdc++: Test for feature test macros more accurately ... Tests which check for feature test macros should use the no_pch option, so that we're really testing for the definition being in the intended header, and not just testing that it's present in <bits/stdc++.h> (which includes all the standard headers and so defines all the macros). libstdc++-v3/ChangeLog: * testsuite/18_support/byte/requirements.cc: Disable PCH. * testsuite/18_support/destroying_delete.cc: Likewise. * testsuite/18_support/source_location/1.cc: Likewise. * testsuite/18_support/source_location/version.cc: Likewise. * testsuite/18_support/type_info/constexpr.cc: Likewise. * testsuite/18_support/uncaught_exceptions/uncaught_exceptions.cc: Likewise. * testsuite/19_diagnostics/stacktrace/output.cc: Likewise. * testsuite/19_diagnostics/stacktrace/synopsis.cc: Likewise. * testsuite/19_diagnostics/stacktrace/version.cc: Likewise. * testsuite/20_util/addressof/requirements/constexpr.cc: Likewise. * testsuite/20_util/allocator_traits/header-2.cc: Likewise. * testsuite/20_util/allocator_traits/header.cc: Likewise. * testsuite/20_util/as_const/1.cc: Likewise.

Patrick Palka	4289f6ceef	libstdc++: Fix std::bind_front perfect forwarding [PR111327] ... In order to properly implement a perfect forwarding call wrapper (without C++23 deducing 'this') we need a total of 8 operator() overloads, 4 enabled ones and 4 deleted ones, i.e. two for each const/ref qual pair, as described in section 5.5 of P0847R6. Otherwise the wrapper may not do the right thing if the underlying function object has a deleted const/ref-qualified operator() overload. This patch fixes this issue in std::bind_front.

Jonathan Wakely	fa9bda3ea4	libstdc++: Make INVOKE<R> refuse to create dangling references [PR70692] ... This is the next part of the library changes from P2255R2. This makes INVOKE<R> ill-formed if converting the INVOKE expression to R would bind a reference to a temporary object. The is_invocable_r trait is now false if the invocation would create a dangling reference. This is done by adding the dangling check to the __is_invocable_impl partial specialization used for INVOKE<R> expressions. This change also slightly simplifies the nothrow checking recently added to that partial specialization. This change also removes the is_invocable_r checks from the pre-C++17 implementation of std::__invoke_r, because there is no need for it to be SFINAE-friendly. None of our C++11 and C++14 uses of INVOKE<R> require those constraints. The std::function constructor needs to check is_invocable_r, but that's already done explicitly, so we don't need to recheck when calling __is_invoke_r in std::function::operator(). The other uses of std::__is_invoke_r do not need to be constrained and can just be ill-formed if the INVOKE<R> expression is ill-formed. libstdc++-v3/ChangeLog: PR libstdc++/70692 * include/bits/invoke.h [__cplusplus < 201703] (__invoke_r): Remove is_invocable and is_convertible constraints. * include/std/type_traits (__is_invocable_impl::_S_conv): Use non-deduced context for parameter.

A change I was working on made constexpr_searcher.cc start to fail, and when I looked at it I wondered why it had been accepted before.

Jonathan Wakely	de196e5dd8	libstdc++: Add attribute to features deprecated in C++17 [PR91260] ... There are a lot of things in the C++ standard library which were deprecated in C++11, and more in C++17. Some of them were removed after deprecation and are no longer present in the standard at all. We have not removed these from libstdc++ because keeping them as non-standard extensions is conforming, and avoids gratuitously breaking user code, and in some cases we need to keep using them to avoid ABI changes. But we should at least give a warning for using them. That has not been done previously because of the library's own uses of them (e.g. the std::iterator class template used as a base class). This adds deprecated attributes to the relevant components, and then goes through the whole library to add diagnostic pragmas where needed to suppress warnings about our internal uses of them. The tests are updated to either expect the additional warnings, or to suppress them where we aren't interested in them. libstdc++-v3/ChangeLog: PR libstdc++/91260 PR libstdc++/91383 PR libstdc++/95065 * include/backward/binders.h (bind1st, bind2nd): Add deprecated attribute. * include/bits/refwrap.h (_Maybe_unary_or_binary_function): Disable deprecated warnings for base classes.

Jonathan Wakely	dcda050e6c	libstdc++: Fix BUILTIN-PTR-CMP helpers ... The helpers that implement BUILTIN-PTR-CMP do not currently check if the arguments are actually comparable, so the concept is true when it shouldn't be. Since we're trying to test for an unambiguous conversion to pointers, we can also require that it returns bool, because the built-in comparisons for pointers do return bool. * include/bits/range_cmp.h (__detail::__eq_builtin_ptr_cmp): Require equality comparison to be valid and return bool.

Split out the C++17 parts to a new file that always runs with -std=gnu++17, so those checks are always done.
