Hi This patch improves stl_algobase.h copy/copy_backward/fill/fill_n/equal implementations. The improvements are: - activation of algo specialization for __gnu_debug::_Safe_iterator (w/o _GLIBCXX_DEBUG mode) - activation of algo specialization for _Deque_iterator even if mixed with another kind of iterator. - activation of algo specializations __copy_move_a2 for something else than pointers. For example this code: std::vector<char> v { 'a', 'b', .... }; ostreambuf_iterator out(std::cout); std::copy(v.begin(), v.end(), out); is not calling the specialization __copy_move_a2(const char*, const char*, ostreambuf_iterator<>); It also fix a _GLIBCXX_DEBUG issue where the __niter_base specialization was wrongly removing the _Safe_iterator<> layer. The testsuite/25_algorithms/copy/debug/1_neg.cc test case was failing on a debug assertion because _after_ the copy we were trying to increment the vector iterator after past-the-end. Of course the problem is the _after_, Debug mode should detect this _before_ it takes place which it does now. Note that std::fill_n is now making use of std::fill for some optimizations dealing with random access iterators. Performances are very good: Before: copy_backward_deque_iterators.cc deque 2 deque 1084r 1084u 0s 0mem 0pf copy_backward_deque_iterators.cc deque 2 vector 3373r 3372u 0s 0mem 0pf copy_backward_deque_iterators.cc vector 2 deque 3316r 3316u 0s 0mem 0pf copy_backward_deque_iterators.cc int deque 2 char vector 3610r 3609u 0s 0mem 0pf copy_backward_deque_iterators.cc char vector 2 int deque 3552r 3552u 0s 0mem 0pf copy_backward_deque_iterators.cc deque 2 list 10528r 10528u 0s 0mem 0pf copy_backward_deque_iterators.cc list 2 deque 2161r 2162u 0s 0mem 0pf copy_deque_iterators.cc deque 2 deque 752r 751u 0s 0mem 0pf copy_deque_iterators.cc deque 2 vector 3300r 3299u 0s 0mem 0pf copy_deque_iterators.cc vector 2 deque 3144r 3140u 0s 0mem 0pf copy_deque_iterators.cc int deque 2 char vector 3340r 3338u 1s 0mem 0pf copy_deque_iterators.cc char vector 2 int deque 3132r 3132u 0s 0mem 0pf copy_deque_iterators.cc deque 2 list 10013r 10012u 0s 0mem 0pf copy_deque_iterators.cc list 2 deque 2274r 2275u 0s 0mem 0pf equal_deque_iterators.cc deque vs deque 8676r 8675u 0s 0mem 0pf equal_deque_iterators.cc deque vs vector 5870r 5870u 0s 0mem 0pf equal_deque_iterators.cc vector vs deque 3163r 3163u 0s 0mem 0pf equal_deque_iterators.cc int deque vs char vector 5845r 5845u 0s 0mem 0pf equal_deque_iterators.cc char vector vs int deque 3307r 3307u 0s 0mem 0pf After: copy_backward_deque_iterators.cc deque 2 deque 697r 697u 0s 0mem 0pf copy_backward_deque_iterators.cc deque 2 vector 219r 218u 0s 0mem 0pf copy_backward_deque_iterators.cc vector 2 deque 453r 453u 0s 0mem 0pf copy_backward_deque_iterators.cc int deque 2 char vector 1914r 1915u 0s 0mem 0pf copy_backward_deque_iterators.cc char vector 2 int deque 2112r 2111u 0s 0mem 0pf copy_backward_deque_iterators.cc deque 2 list 7770r 7771u 0s 0mem 0pf copy_backward_deque_iterators.cc list 2 deque 2194r 2193u 0s 0mem 0pf copy_deque_iterators.cc deque 2 deque 505r 504u 0s 0mem 0pf copy_deque_iterators.cc deque 2 vector 221r 221u 0s 0mem 0pf copy_deque_iterators.cc vector 2 deque 398r 397u 0s 0mem 0pf copy_deque_iterators.cc int deque 2 char vector 1770r 1767u 0s 0mem 0pf copy_deque_iterators.cc char vector 2 int deque 1995r 1993u 0s 0mem 0pf copy_deque_iterators.cc deque 2 list 7650r 7641u 2s 0mem 0pf copy_deque_iterators.cc list 2 deque 2270r 2270u 0s 0mem 0pf equal_deque_iterators.cc deque vs deque 769r 768u 0s 0mem 0pf equal_deque_iterators.cc deque vs vector 231r 230u 0s 0mem 0pf equal_deque_iterators.cc vector vs deque 397r 397u 0s 0mem 0pf equal_deque_iterators.cc int deque vs char vector 1541r 1541u 0s 0mem 0pf equal_deque_iterators.cc char vector vs int deque 1623r 1623u 0s 0mem 0pf In Debug Mode it is of course even better.

I plan to do a refinement to also cover this use case. In Debug implementations I have duplicated the Debug checks because those algo specialization will also be used when users are directly using <debug/vector> for instance without defining _GLIBCXX_DEBUG. All algos tests passed except the constexpr ones in Debug mode, I've put this on my todo list. Ok to commit once I completed all the other tests ?
