2021-05-24libstdc++: Limit allocation on iterator insertion in Hashtable [PR 96088]François Dumont7-22/+782
When inserting into unordered_multiset or unordered_multimap first instantiate the node to store and compute the hash code from it to avoid a potential intermediate key_type instantiation. When inserting into unordered_set or unordered_map check if invoking the hash functor with container key_type is noexcept and invoking the same hash functor with key part of the iterator value_type can throw. In this case create a temporary key_type instance at Hashtable level and use it to compute the hash code. This temporary instance is moved to the final storage location if needed. libstdc++-v3/ChangeLog: PR libstdc++/96088 * include/bits/hashtable_policy.h (_Select2nd): New. (_NodeBuilder<>): New.

2021-05-24libstdc++: Fix iterator caching inside range adaptors [PR100479]Patrick Palka2-67/+201
This fixes two issues with our iterator caching as described in detail in the PR. Since we recently added the __non_propagating_cache class template as part of r12-336 for P2328, this patch just rewrites the problematic _CachedPosition partial specialization in terms of this class template. For the offset partial specialization, it's safe to propagate the cached offset on copy/move, but we should still invalidate the cached offset in the source object on move. libstdc++-v3/ChangeLog: PR libstdc++/100479 * include/std/ranges (__detail::__non_propagating_cache): Move definition up to before that of _CachedPosition. Make base class _Optional_base protected instead of private. Add const overload for operator*. (__detail::_CachedPosition): Rewrite the partial specialization for forward ranges as a derived class of __non_propagating_cache. Remove the size constraint on the partial specialization for random access ranges. Add copy/move/copy-assignment/move-assignment members to the offset partial specialization for random access ranges that propagate the cached value but additionally invalidate it in the source object on move. * testsuite/std/ranges/adaptors/100479.cc: New test.

2021-05-20libstdc++: Use __builtin_unreachable for constexpr assertions [PR 100676]Jonathan Wakely11-33/+29
The current implementation of compile-time precondition checks causes compilation to fail by calling a non-constexpr function declared at block scope. This breaks the CUDA compiler, which wraps some libstdc++ headers in a pragma that declares everything as a __host__ __device__ function, but others are not wrapped and so everything is a __host__ function. The local declaration thus gets redeclared as two different types of function, which doesn't work. Just use __builtin_unreachable to make constant evaluation fail, instead of the local function declaration. Also simplify the assertion macros, which has the side effect of giving simpler compilation errors when using Clang. libstdc++-v3/ChangeLog: PR libstdc++/100676 * include/bits/c++config (__glibcxx_assert_1): Rename to ...

2021-05-17libstdc++: Fix filesystem::path constraints for volatile [PR 100630]Jonathan Wakely3-1/+29
The constraint check for filesystem::path construction uses decltype(__is_path_src(declval<Source>())) which mean it considers conversion from an rvalue. When Source is a volatile-qualified type it cannot use is_path_src(const Unknown&) because a const lvalue reference can only bind to a non-volatile rvalue. Since the relevant path members all have a const Source& parameter, the constraint should be defined in terms of declval<const Source&>(), not declval<Source>(). This avoids the problem of volatile-qualified rvalues, because we no longer use an rvalue at all. libstdc++-v3/ChangeLog: PR libstdc++/100630 * include/experimental/bits/fs_path.h (__is_constructible_from): Test construction from a const lvalue, not an rvalue. * testsuite/27_io/filesystem/path/construct/100630.cc: New test. * testsuite/experimental/filesystem/path/construct/100630.cc: New test.

2021-05-17libstdc++: Allow lualatex to be used for Doxygen PDFJonathan Wakely4-59/+78
This allows the Doxygen PDF to be built using lualatex instead of pdflatex, which solves a problem with pdflatex running out of memory sometimes. This is done by adding a --latex_cmd option to the run_doxygen script, which then sets the specified command in the generated user.cfg file used by Doxygen. The makefile is adjusted to pass --latex_cmd=$(LATEX_CMD) to the script, so using running make with LATEX_CMD=lualatex will override the default. Additionally, this does some refactoring of the doc/Makefile.am rules and the run_doxygen script. libstdc++-v3/ChangeLog: * doc/Makefile.am: Simplify doxygen recipes and use --latex_cmd. * doc/Makefile.in: Regenerate. * doc/doxygen/user.cfg.in (LATEX_CMD_NAME): Add placeholder value. * scripts/run_doxygen (print_usage): Always print to stdout and do not exit.

floating_to_chars.cc includes the Ryu sources into an anonymous namespace as a convenient way to give all its symbols internal linkage. But an entity declared extern "C" always has external linkage even from within an anonymous namespace, so this trick doesn't work in the presence of extern "C", and it causes the Ryu function generic_to_chars to be visible from libstdc++.a.

This has been tentatively approved by LWG. The deleter from a unique_ptr can be moved into the shared_ptr (at least, since LWG 2802). This uses std::forward<_Del>(__r.get_deleter()) not std::move(__r.get_deleter()) because we don't want to convert the deleter to an rvalue when _Del is an lvalue reference type. This also adds a missing is_move_constructible_v<D> constraint to the shared_ptr(unique_ptr<Y, D>&&) constructor, which is inherited from the shared_ptr(Y*, D) constructor due to the use of "equivalent to" in the specified effects. libstdc++-v3/ChangeLog: * include/bits/shared_ptr_base.h (__shared_count(unique_ptr&&)): Initialize a non-reference deleter from an rvalue, as per LWG 3548.

GCC defaults to -std=gnu++17 now anyway, and using it explicitly in the dg-options directive prevents running these tests with different modes such as -std=c++17 or -std=gnu++20. libstdc++-v3/ChangeLog: * testsuite/20_util/specialized_algorithms/pstl/uninitialized_construct.cc: Remove -std=gnu++17 from dg-options. * testsuite/20_util/specialized_algorithms/pstl/uninitialized_copy_move.cc: Likewise. * testsuite/20_util/specialized_algorithms/pstl/uninitialized_fill_destroy.cc: Likewise. * testsuite/25_algorithms/pstl/alg_merge/inplace_merge.cc: Likewise. * testsuite/25_algorithms/pstl/alg_merge/merge.cc: Likewise. * testsuite/25_algorithms/pstl/alg_modifying_operations/copy_if.cc: Likewise. * testsuite/25_algorithms/pstl/alg_modifying_operations/copy_move.cc: Likewise. * testsuite/25_algorithms/pstl/alg_modifying_operations/fill.cc: Likewise. * testsuite/25_algorithms/pstl/alg_modifying_operations/generate.cc: Likewise. * testsuite/25_algorithms/pstl/alg_modifying_operations/is_partitioned.cc: Likewise. * testsuite/25_algorithms/pstl/alg_modifying_operations/partition.cc: Likewise. * testsuite/25_algorithms/pstl/alg_modifying_operations/partition_copy.cc: Likewise. * testsuite/25_algorithms/pstl/alg_modifying_operations/remove.cc: Likewise. * testsuite/25_algorithms/pstl/alg_modifying_operations/remove_copy.cc: Likewise. * testsuite/25_algorithms/pstl/alg_modifying_operations/replace.cc: Likewise. * testsuite/25_algorithms/pstl/alg_modifying_operations/replace_copy.cc: Likewise. * testsuite/25_algorithms/pstl/alg_modifying_operations/rotate.cc: Likewise. * testsuite/25_algorithms/pstl/alg_modifying_operations/rotate_copy.cc: Likewise. * testsuite/25_algorithms/pstl/alg_modifying_operations/swap_ranges.cc: Likewise. * testsuite/25_algorithms/pstl/alg_modifying_operations/transform_binary.cc: Likewise. * testsuite/25_algorithms/pstl/alg_modifying_operations/transform_unary.cc: Likewise. * testsuite/25_algorithms/pstl/alg_modifying_operations/unique.cc: Likewise. * testsuite/25_algorithms/pstl/alg_modifying_operations/unique_copy_equal.cc: Likewise. * testsuite/25_algorithms/pstl/alg_nonmodifying/adjacent_find.cc: Likewise. * testsuite/25_algorithms/pstl/alg_nonmodifying/all_of.cc: Likewise. * testsuite/25_algorithms/pstl/alg_nonmodifying/any_of.cc: Likewise. * testsuite/25_algorithms/pstl/alg_nonmodifying/count.cc: Likewise. * testsuite/25_algorithms/pstl/alg_nonmodifying/equal.cc: Likewise. * testsuite/25_algorithms/pstl/alg_nonmodifying/find.cc: Likewise. * testsuite/25_algorithms/pstl/alg_nonmodifying/find_end.cc: Likewise. * testsuite/25_algorithms/pstl/alg_nonmodifying/find_first_of.cc: Likewise. * testsuite/25_algorithms/pstl/alg_nonmodifying/find_if.cc: Likewise. * testsuite/25_algorithms/pstl/alg_nonmodifying/for_each.cc: Likewise. * testsuite/25_algorithms/pstl/alg_nonmodifying/mismatch.cc: Likewise. * testsuite/25_algorithms/pstl/alg_nonmodifying/none_of.cc: Likewise. * testsuite/25_algorithms/pstl/alg_nonmodifying/nth_element.cc: Likewise. * testsuite/25_algorithms/pstl/alg_nonmodifying/reverse.cc: Likewise. * testsuite/25_algorithms/pstl/alg_nonmodifying/reverse_copy.cc: Likewise. * testsuite/25_algorithms/pstl/alg_nonmodifying/search_n.cc: Likewise. * testsuite/25_algorithms/pstl/alg_sorting/includes.cc: Likewise. * testsuite/25_algorithms/pstl/alg_sorting/is_heap.cc: Likewise. * testsuite/25_algorithms/pstl/alg_sorting/is_sorted.cc: Likewise. * testsuite/25_algorithms/pstl/alg_sorting/lexicographical_compare.cc: Likewise. * testsuite/25_algorithms/pstl/alg_sorting/minmax_element.cc: Likewise. * testsuite/25_algorithms/pstl/alg_sorting/partial_sort.cc: Likewise. * testsuite/25_algorithms/pstl/alg_sorting/partial_sort_copy.cc: Likewise. * testsuite/25_algorithms/pstl/alg_sorting/set.cc: Likewise. * testsuite/25_algorithms/pstl/alg_sorting/sort.cc: Likewise. * testsuite/25_algorithms/pstl/feature_test-2.cc: Likewise. * testsuite/25_algorithms/pstl/feature_test-3.cc: Likewise. * testsuite/25_algorithms/pstl/feature_test-4.cc: Likewise. * testsuite/25_algorithms/pstl/feature_test-5.cc: Likewise. * testsuite/25_algorithms/pstl/feature_test.cc: Likewise. * testsuite/26_numerics/pstl/numeric_ops/adjacent_difference.cc: Likewise. * testsuite/26_numerics/pstl/numeric_ops/reduce.cc: Likewise. * testsuite/26_numerics/pstl/numeric_ops/scan.cc: Likewise. * testsuite/26_numerics/pstl/numeric_ops/transform_reduce.cc: Likewise. * testsuite/26_numerics/pstl/numeric_ops/transform_scan.cc: Likewise.

2021-05-10libstdc++: Rename test type to avoid clashing with std::anyJonathan Wakely1-4/+4
When PCH are enabled this test file includes <any> and so the using-directive brings std::any into the global scope. It isn't currently a problem, because the -std option in the dg-options means that PCH is not used. If that option is removed, the test fails with PCH and passes without. This just renames the type to avoid the name classh (and also the 'none' type for consistency). libstdc++-v3/ChangeLog: * testsuite/20_util/variant/compile.cc: Rename 'any' to avoid clash with std::any.

2021-05-07libstdc++: Fix constraints for rvalue stream insertion/extractionJonathan Wakely8-28/+64
The __rval_streamable() function was an attempt to test for convertibility cheaply and without confusing diagnostics. It doesn't work with Clang though, and is probably ill-formed. Replace that helper function with a check for derivation from ios_base, and use that in the alias templates __rvalue_stream_insertion_t and __rvalue_stream_extraction_t. Use concepts for the constraints when available. libstdc++-v3/ChangeLog: * include/std/istream (__rvalue_stream_extraction_t): Replace use of __rval_streamable. * include/std/ostream (__rvalue_stream_insertion_t): Likewise. (__rval_streamable): Remove. (_Require_derived_from_ios_base, __derived_from_ios_base): New helper for checking constraints. * testsuite/27_io/basic_istream/extractors_other/char/4.cc: Fix reference to the wrong subclause of the standard. * testsuite/27_io/basic_istream/extractors_other/wchar_t/4.cc: Likewise. * testsuite/27_io/basic_ostream/inserters_other/char/6.cc: Likewise. * testsuite/27_io/basic_ostream/inserters_other/wchar_t/6.cc: Likewise. * testsuite/27_io/basic_ostream/inserters_other/char/99692.cc: New test. * testsuite/27_io/filesystem/path/io/dr2989.cc: Adjust pruned errors.

2021-05-06libstdc++: Improve static assert messagesJonathan Wakely3-4/+4
The message used for static assertions should be phrased so that it's unambiguous whether the condition should be true or false. The message should definitely not state the negative condition. libstdc++-v3/ChangeLog: * include/bits/stl_algobase.h (__copy_move, __copy_move_backward): Improve static_assert messages. * testsuite/25_algorithms/copy/58982.cc: Adjust expected output. * testsuite/25_algorithms/copy_n/58982.cc: Likewise.

2021-05-06libstdc++: Fix definition of std::remove_cvref_tJonathan Wakely2-4/+20
I originally defined std::remove_cvref_t in terms of the internal __remove_cvref_t trait, to avoid instantiating the remove_cvref class template. However, as described in P1715R0 that is observable by users and is thus non-conforming. This defines remove_cvref_t as specified in the standard. libstdc++-v3/ChangeLog: * include/std/type_traits (remove_cvref_t): Define in terms of remove_cvref. * testsuite/20_util/remove_cvref/value.cc: Check alias.
