2022-10-10libstdc++: Revert addition of constraints to make_signed/make_unsignedJonathan Wakely6-12/+19
Constraining the primary template makes it unusable in uninstantiated contexts. libstdc++-v3/ChangeLog: * include/std/type_traits (make_signed, make_unsigned): Remove constraints on primary template. * testsuite/20_util/make_signed/requirements/typedefs_neg.cc: Undo changes to expected error in C++20 mode. * testsuite/20_util/make_unsigned/requirements/typedefs_neg.cc: Likewise. * testsuite/24_iterators/range_access/range_access_cpp20_neg.cc: Likewise. * testsuite/20_util/make_signed/requirements/uninstantiated.cc: New test. * testsuite/20_util/make_unsigned/requirements/uninstantiated.cc: New test.
2022-10-10libstdc++: std::make_signed_t<cv bool> should be ill-formedJonathan Wakely5-34/+40
Currently we only reject std::make_signed_t<bool> but not cv bool. Similarly for std::make_unsigned_t<cv bool>. As well as making those ill-formed, this adds a requires-clause to the make_signed and make_unsigned primary templates. This makes non-integral, non-enum cases fail immediately with a clear error, rather than giving an error about __make_signed_selector<T, false, false> being incomplete. libstdc++-v3/ChangeLog: * include/std/type_traits (make_signed, make_unsigned): Add specializations for cv bool. Add requires-clause for C++20 to improve diagnostics for non-integral, non-enum cases. * testsuite/20_util/make_signed/requirements/typedefs_neg.cc: Check cv bool. * testsuite/20_util/make_unsigned/requirements/typedefs_neg.cc: Likewise. * testsuite/24_iterators/range_access/range_access_cpp20_neg.cc: Adjust expected errors for C++20 and later. * testsuite/lib/prune.exp: Prune "in requirements [with ...]" lines from diagnostics.

2022-10-07libstdc++: Add --disable-libstdcxx-hosted as an alias for hosted-libstdcxxJonathan Wakely2-10/+49
Most libstdc++ configure args are of the form --enable-libstdcxx-xxx but the option to build freestanding is --disable-hosted-libstdcxx. If you accidentally type --disable-libstdcxx-hosted then it will be ignored. This adds --disable-libstdcxx-hosted as an alias for the existing arg, so it works whichever way you say it. If both args are used explicitly and their values do not agree, configure fails with an error. libstdc++-v3/ChangeLog: * acinclude.m4 (GLIBCXX_ENABLE_HOSTED): Add libstdcxx-hosted enable arg as an alias for hosted-libstdcxx enable arg. * configure: Regenerate.
2022-10-07libstdc++: Shuffle header dependencies of <functional>Jonathan Wakely2-9/+8
The <new> header is needed by std::function to use placement new, so include it in <bits/std_function.h> instead of in <functional>. libstdc++-v3/ChangeLog: * include/bits/std_function.h: Include <new> but do not include <bits/stl_function.h>. * include/std/functional: Do not include <new>.
2022-10-07libstdc++: Use bold style for DR titles in the manualJonathan Wakely2-397/+390
This matches how the issues are styled in the LWG issues list, and also allows us to use italics for "cv" (e.g. in issue 2487). libstdc++-v3/ChangeLog: * doc/xml/manual/intro.xml: Add role="bold" attribute to emphasis elements for issue titles. * doc/html/manual/bugs.html: Regenerate.

2022-10-05libstdc++: Guard use of new built-in with __has_builtinJonathan Wakely1-0/+2
Another case where I forgot that non-GCC compilers don't have this built-in yet. libstdc++-v3/ChangeLog: * include/bits/invoke.h (__invoke_r): Check __has_builtin(__reference_converts_from_temporary) before using built-in.

2022-10-04libstdc++: Fix test FAIL for old std::string ABIJonathan Wakely1-3/+9
libstdc++-v3/ChangeLog: * testsuite/std/ranges/adaptors/join_with/1.cc: Remove unused <sstream header. (test04): Remove constexpr for old std::string ABI and test at runtime.
2022-10-04libstdc++: Use new built-ins __remove_cv, __remove_reference etc.Jonathan Wakely1-9/+24
libstdc++-v3/ChangeLog: * include/std/type_traits (remove_cv): Use __remove_cv built-in. (remove_reference): Use __remove_reference built-in. (remove_cvref): Use __remove_cvref built-in. Remove inheritance for fallback implementation.
2022-10-04libstdc++: Refactor seed sequence constraints in <random>Jonathan Wakely2-18/+27
Every use of _If_seed_seq in <random> and <ext/random> uses it with enable_if. We can just move the enable_if into the helper alias instead of repeating it everywhere. libstdc++-v3/ChangeLog: * include/bits/random.h (__is_seed_seq): Replace with ... (_If_seed_seq_for): ... this. * include/ext/random: Adjust to use _If_seed_seq_for.

2022-10-04libstdc++: Disable test for freestandingJonathan Wakely1-0/+2
This test checks the exception-safety of std::stable_sort if copying a value throws. For freestanding we don't allocate in std::stable_sort anyway, and the exception thrown via __throw_runtime_error terminates, so disable the test. libstdc++-v3/ChangeLog: * testsuite/25_algorithms/stable_sort/mem_check.cc: Do nto run for freestanding.
2022-10-04libstdc++: Enable std::hash<coroutine_handle<P>> [PR107139]Jonathan Wakely1-8/+2
Everything that <coroutine> depends on is available for freestanding now. libstdc++-v3/ChangeLog: PR libstdc++/107139 * include/std/coroutine: Remove all _GLIBCXXHOSTED preprocessor conditionals.
2022-10-04libstdc++: Make <cstdint> work freestanding [PR107134]Jonathan Wakely1-2/+57
When gcc/config.gcc defines use_gcc_stdin=wrap, GCC's <stdint.h> tries to use libc's <stdint.h> unless -ffreestanding is used. When libstdc++ is configured --disable-hosted-libstdcxx we want <cstdint> to work even without -ffreestanding being given. This is a kluge to make it include GCC's <stdint-gcc.h> directly even without -ffreestanding. libstdc++-v3/ChangeLog: PR libstdc++/107134 * include/c_global/cstdint [!_GLIBCXX_HOSTED]: Include <stdint-gcc.h> directly.
2022-10-04libstdc++: Define <bits/functexcept.h> functions for freestanding [PR107135]Jonathan Wakely2-7/+26
We don't compile src/c++11/functexcept.cc for freestanding, so just define the functions used by freestanding entities as inline calls to std::terminate. libstdc++-v3/ChangeLog: PR libstdc++/107135 * include/bits/functexcept.h [!_GLIBCXX_HOSTED] (__throw_invalid_argument, __throw_out_of_range) (__throw_out_of_range_fmt, __throw_runtime_error) (__throw_overflow_error): Define inline. * include/std/bitset (_M_copy_from_ptr) [!_GLIBCXX_HOSTED]: Replace __builtin_abort with __throw_invalid_argument.

2022-10-03libstdc++: Filter out unconditional <stdio.h> default includeArsen Arsenović2-8/+26
_AC_INCLUDES_DEFAULT_REQUIREMENTS including <stdio.h> when checking for stdint.h has prevented proper detection of whether stdint.h is present, since it'd poison the cache variables with test results failing due to <stdio.h> failing to include. As a solution, for autoconf versions under 2.70, we filter out that bit of code from ac_includes_default. This issue was fixed in autoconf-2.70. This also applies to various other headers, but was noticed when looking into why HAVE_STDINT_H was misdefined. libstdc++-v3/ChangeLog: * configure.ac: Remove any lines that unconditionally include <stdio.h> from ac_includes_default, when running Autoconf <2.70. * configure: Regenerate.

In C++23 mode these tests started to FAIL because an rvalue reference parameter can no longer be bound to an lvalue reference return type. As confirmed by Ville (who added these tests) the problem overloads are not intended to be called, and only exist to verify that they don't interfere with the intended behaviour.

2022-09-30libstdc++: Optimize operator>> for std::bitsetJonathan Wakely1-9/+27
We can improve performance by using a char buffer instead of basic_string. The loop bound already means we can't overflow the buffer, and we don't need to keep writing a null character after every character written to the buffer. We could just use basic_string::resize(N) to zero-init the whole string, then overwrite those chars. But that zero-init of all N chars would be wasted in the case where we are writing to a bitset<N> with large N, but only end up extracting one or two chars from the stream. With this change we just use buffer of uninitialized chars. For a small-ish bitset (currently <= 256) we can improve performance further by using alloca instead of the heap. libstdc++-v3/ChangeLog: * include/std/bitset (operator>>): Use a simple buffer instead of std::basic_string.
2022-09-30libstdc++: Remove non-standard public members in std::bitsetJonathan Wakely1-36/+33

Also remove the historical _M_copy_from_string and _M_copy_to_string overloads. Those were used before DR 396 was implemented but are not needed now. There are no tests or docs describing them, so I don't think we intend to support them as extensions. libstdc++-v3/ChangeLog: * include/std/bitset (_M_copy_from_ptr, _M_copy_from_string) (_M_copy_to_string): Change access to private.

This implements that change. libstdc++-v3/ChangeLog: * doc/xml/manual/evolution.xml: Document std::bind API changes. * doc/xml/manual/intro.xml: Document LWG 2487 status. * doc/xml/manual/using.xml: Clarify default value of _GLIBCXX_USE_DEPRECATED. * doc/html/*: Regenerate. * include/std/functional (_Bind::operator()(Args&&...) volatile) (_Bind::operator()(Args&&...) const volatile) (_Bind_result::operator()(Args&&...) volatile) (_Bind_result::operator()(Args&&...) const volatile): Replace with deleted overload for C++20 and later. * testsuite/20_util/bind/cv_quals.cc: Check for deprecated warnings in C++17. * testsuite/20_util/bind/cv_quals_2.cc: Likewise, and check for ill-formed in C++20.
2022-09-29libstdc++: Make INVOKE<R> refuse to create dangling references [PR70692]Jonathan Wakely7-28/+80
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. (__is_invocable_impl::_S_test): Remove _Check_noex template parameter and use deduced noexcept value in its place. Add bool parameter to detect dangling references. (__is_invocable_impl::type): Adjust call to _S_test to avoid deducing unnecessary noexcept property.. (__is_invocable_impl::__nothrow_type): Rename to ...
