Remove __cplusplus > 201703L checks that are redundant when used alongside __glibcxx_concepts checks, because <version> already guarantees that __glibcxx_concepts is only defined for C++20 and later. Prefer to check __glibcxx_ranges for features such as move_sentinel that were added by the One Ranges proposal (P0896R4), or for features which depend on other components introduced by that proposal. But prefer to check __glibcxx_concepts for constraints that only depend on requires-clauses and concepts defined in <concepts>, even if those constraints were added by the Ranges proposal (e.g. the constraints on non-member operators for move_iterator). Prefer #ifdef to #if when just testing for the presence of __glibcxx_foo macros with caring about their value. Also add/tweak some Doxygen comments. libstdc++-v3/ChangeLog: * include/bits/stl_iterator.h: Make use of feature test macros more consistent. Improve doxygen comments. |
