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. Signed-off-by: Jonathan Wakely <jwakely@redhat.com> libstdc++-v3/ChangeLog: PR libstdc++/101258 * doc/doxygen/user.cfg.in (INPUT): Add <experimental/simd>. (COLS_IN_ALPHA_INDEX): Remove obsolete tag. (PREDEFINED): Add/fix some more macros that need to be expanded. * include/bits/random.h: Stop Doxygen from documenting internal implementation details. * include/bits/random.tcc: Likewise. * include/bits/this_thread_sleep.h: Fix @file name. * include/experimental/bits/simd.h: Add to Doxygen group. Do not document internal implementation details. * include/experimental/bits/simd_detail.h: Do not document internal implementation details. * include/experimental/simd: Define Doxygen groups. * include/experimental/type_traits: Improve documentation for the header file. Define groups. Use @since commands. * include/std/scoped_allocator (scoped_allocator_adaptor): Move declaration before undocumented region. * include/std/type_traits (true_type, false_type): Use using declaration instead of typedef. (is_invocable_v, is_nothrow_invocable_v, is_invocable_r_v) (is_nothrow_invocable_r_v): Move definitions next to other C++17 variable templates. Do not document internal implementation details. Move misplaced group-end command. Define group for variable templates. * include/std/variant: Do not document internal implementation details. * testsuite/26_numerics/random/pr60037-neg.cc: Adjust dg-error line number.
