From: Jonathan Wakely Date: Tue, 2 Jun 2020 17:13:08 +0000 (+0100) Subject: libstdc++: Make debug containers prefer copy ctor to base ctor (PR 90102) X-Git-Tag: upstream/12.2.0~16122 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=eca833b81289438ec5ae3ed4c77ffb49cfb65f34;p=platform%2Fupstream%2Fgcc.git libstdc++: Make debug containers prefer copy ctor to base ctor (PR 90102) When given a type which can convert to any container-like type, the C(const C&) copy constructor and C(const C::_Base&) converting constructor are ambiguous. This change replaces the converting constructor's parameter with a reference_wrapper-like type so that calling that constructor requires an additional user-defined conversion. This gives it a lower rank than the copy constructor, avoiding the ambiguity. While testing this change I discovered that __gnu_debug::forward_list doesn't have a convering constructor from the std::forward_list base, so this adds it. We should probably consider whether the converting constructors should be 'explicit' but I'm not changing that now. libstdc++-v3/ChangeLog: PR libstdc++/90102 * include/debug/deque (deque(const _Base&)): Replace parameter with a struct that wraps a const _Base&. * include/debug/forward_list (forward_list(_Base_ref)): New constructor. * include/debug/list (list(const _Base&)): Replace parameter with a struct that wraps a const _Base&. * include/debug/map.h (map(const _Base&)): Likewise. * include/debug/multimap.h (multimap(const _Base&)): Likewise. * include/debug/multiset.h (multiset(const _Base&)): Likewise. * include/debug/set.h (set(const _Base&)): Likewise. * include/debug/unordered_map (unordered_map(const _Base&)) (unordered_multimap(const _Base&)): Likewise. * include/debug/unordered_set (unordered_set(const _Base&)) (unordered_multiset(const _Base&)): Likewise. * testsuite/23_containers/vector/cons/destructible_debug_neg.cc: Adjust dg-error line number. * include/debug/vector (vector(const _Base&)): Likewise. * testsuite/23_containers/deque/debug/90102.cc: New test. * testsuite/23_containers/forward_list/debug/90102.cc: New test. * testsuite/23_containers/list/debug/90102.cc: New test. * testsuite/23_containers/map/debug/90102.cc: New test. * testsuite/23_containers/multimap/debug/90102.cc: New test. * testsuite/23_containers/multiset/debug/90102.cc: New test. * testsuite/23_containers/set/debug/90102.cc: New test. * testsuite/23_containers/unordered_map/debug/90102.cc: New test. * testsuite/23_containers/unordered_multimap/debug/90102.cc: New test. * testsuite/23_containers/unordered_multiset/debug/90102.cc: New test. * testsuite/23_containers/unordered_set/debug/90102.cc: New test. * testsuite/23_containers/vector/debug/90102.cc: New test. --- diff --git a/libstdc++-v3/include/debug/deque b/libstdc++-v3/include/debug/deque index 4d525bf..2bb9902 100644 --- a/libstdc++-v3/include/debug/deque +++ b/libstdc++-v3/include/debug/deque @@ -64,6 +64,16 @@ namespace __debug template friend class ::__gnu_debug::_Safe_iterator; + // Reference wrapper for base class.
