2024-09-25libstdc++: #ifdef out #pragma GCC system_headerJason Merrill
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

2023-11-16libstdc++: Only declare feature test macros in standard headersJonathan Wakely
This change moves the definitions of feature test macros (or strictly speaking, the requests for <bits/version.h> to define them) so that only standard headers define them. For example, <bits/shared_ptr.h> will no longer define macros related to std::shared_ptr, only <memory> and <version> will define them. This means that __cpp_lib_shared_ptr_arrays will not be defined by <future> or by other headers that include <bits/shared_ptr.h>. It will only be defined when <memory> has been included. This will discourage users from relying on transitive includes. As a result, internal headers that need to query the macros should use the internal macros like __glibcxx_shared_ptr_arrays instead of __cpp_lib_shared_ptr_arrays, as those internal macros are defined by the internal headers after icluding <bits/version.h>. There are some exceptions to this rule, because __cpp_lib_is_constant_evaluated is defined by bits/c++config.h and so is available everywhere, and __cpp_lib_three_way_comparison is defined by <compare> which several headers are explicitly specified to include, so its macro is guaranteed to be usable too. N.B. not many internal headers actually need an explicit include of <bits/version.h>, because most of them include <type_traits> and so get all the __glibcxx_foo internal macros from there. libstdc++-v3/ChangeLog: * include/bits/algorithmfwd.h: Do not define standard feature test macro here. * include/bits/align.h: Likewise.

2021-07-01libstdc++: Improve Doxygen documentation groups [PR 101258]Jonathan Wakely
This defines some new Doxygen groups for C++17 variable templates and for the contents of <experimental/type_traits>. By documenting the group as a whole and adding each template to a group we don't need to document them individually. Also mark more internals with "@cond undocumented" so that Doxygen ignores them by default. Also make Doxygen process <experimental/simd>. For some reason, many of the class templates in <type_traits> do not appear in the "Metaprogramming" group. For example, add_cv, remove_extent, and all the is_xxx_constructible and is_xxx_assignable traits. For some reason, Doxygen doesn't include them in the group, despite doing it correctly for other traits in the same header.

2020-10-22libstdc++: Reduce header dependencies in and on <memory>Jonathan Wakely
By moving std::make_obj_using_allocator and the related "utility functions for uses-allocator construction" to a new header, we can avoid including the whole of <memory> in <scoped_allocator> and <memory_resource>. In order to simplify the implementation of those utility functions they now use concepts unconditionally. They are no longer defined if __cpp_concepts is not defined. To simplify the code that uses those functions I've introduced a __cpp_lib_make_obj_using_allocator feature test macro (not specified in the standard, which might be an oversight). That allows the code in <memory_resource> and <scoped_allocator> to check the feature test macro to decide whether to use the new utilities, or fall back to the C++17 code. At the same time, this reshuffles some of the headers included by <memory> so that they are (mostly?) self-contained. It should no longer be necessary to include other headers before <bits/shared_ptr.h> when other parts of the library want to use std::shared_ptr without including the whole of <memory>. libstdc++-v3/ChangeLog: * include/Makefile.am: Add new header. * include/Makefile.in: Regenerate. * include/bits/shared_ptr.h: Include <iosfwd>. * include/bits/shared_ptr_base.h: Include required headers here directly, instead of in <memory>. * include/bits/uses_allocator_args.h: New file.
