2094. duration conversion overflow shouldn't participate in overload resolution
This wording is relative to the FDIS.
Change the following paragraphs of 20.11.5.1 [time.duration.cons] p4 indicated:
template <class Rep2, class Period2> constexpr duration(const duration<Rep2, Period2>& d);Remarks: This constructor shall not participate in overload resolution unless no overflow is induced in the conversion and treat_as_floating_point<rep>::value is true or both ratio_divide<Period2, period>::den is 1 and treat_as_floating_point<Rep2>::value is false. [ Note: This requirement prevents implicit truncation error when converting between integral-based duration types. Such a construction could easily lead to confusion about the value of the duration. - end note ]
2122. merge() stability for lists versus forward lists
This wording is relative to the N3485.
Change 17.6.5.7 [algorithm.stable]/1 as indicated:
When the requirements for an algorithm state that it is "stable" without further elaboration, it means:
[.]
- For the merge algorithms, for equivalent elements in the original two ranges, the elements from the first range (preserving their original order) precede the elements from the second range (preserving their original order).
Change 23.3.4.6 [forwardlist.ops] as indicated:
void remove(const T& value); template <class Predicate> void remove_if(Predicate pred);-12- Effects: Erases all the elements in the list referred by a list iterator i for which the following conditions hold: *i == value (for remove()), pred(*i) is true (for remove_if()).
This operation shall be stable: the relative order of the elements that are not removed is the same as their relative order in the original list.Invalidates only the iterators and references to the erased elements.-13- Throws: Nothing unless an exception is thrown by the equality comparison or the predicate.
-??- Remarks: Stable (17.6.5.7 [algorithm.stable]).
[.]
void merge(forward_list& x); void merge(forward_list&& x); template <class Compare> void merge(forward_list& x, Compare comp) template <class Compare> void merge(forward_list&& x, Compare comp)[.]
-19- Effects: Merges
x into *thisthe two sorted ranges [begin(), end()) and [x.begin(), x.end()).This operation shall be stable: for equivalent elements in the two lists, the elements from *this shall always precede the elements from x.x is empty after the merge. If an exception is thrown other than by a comparison there are no effects. Pointers and references to the moved elements of x now refer to those same elements but as members of *this. Iterators referring to the moved elements will continue to refer to their elements, but they now behave as iterators into *this, not into x.-20- Remarks: Stable (17.6.5.7 [algorithm.stable]). The behavior is undefined if this->get_allocator() != x.get_allocator().
[.]
void sort(); template <class Compare> void sort(Compare comp);[.]
-23- Effects: Sorts the list according to the operator< or the comp function object.
This operation shall be stable: the relative order of the equivalent elements is preserved.If an exception is thrown the order of the elements in *this is unspecified. Does not affect the validity of iterators and references.-??- Remarks: Stable (17.6.5.7 [algorithm.stable]).
[.]
Change 23.3.5.5 [list.ops] as indicated:
void remove(const T& value); template <class Predicate> void remove_if(Predicate pred);[.]
-17- Remarks: Stable (17.6.5.7 [algorithm.stable]).
[.]
void merge(list& x); void merge(list&& x); template <class Compare> void merge(list& x, Compare comp) template <class Compare> void merge(list&& x, Compare comp)[.]
-24- Remarks: Stable (17.6.5.7 [algorithm.stable]). [.]
[.]
void sort(); template <class Compare> void sort(Compare comp);[.]
-30- Remarks: Stable (17.6.5.7 [algorithm.stable]).
[.]
Change 25.3.1 [alg.copy]/12 as indicated:
template<class InputIterator, class OutputIterator, class Predicate> OutputIterator copy_if(InputIterator first, InputIterator last, OutputIterator result, Predicate pred);[.]
-12- Remarks: Stable (17.6.5.7 [algorithm.stable]).
Change 25.3.8 [alg.remove] as indicated:
template<class ForwardIterator, class T> ForwardIterator remove(ForwardIterator first, ForwardIterator last, const T& value); template<class ForwardIterator, class Predicate> ForwardIterator remove_if(ForwardIterator first, ForwardIterator last, Predicate pred);[.]
-4- Remarks: Stable (17.6.5.7 [algorithm.stable]).
[.]
template<class InputIterator, class OutputIterator, class T> OutputIterator remove_copy(InputIterator first, InputIterator last, OutputIterator result, const T& value); template<class InputIterator, class OutputIterator, class Predicate> OutputIterator remove_copy_if(InputIterator first, InputIterator last, OutputIterator result, Predicate pred);[.]
-11- Remarks: Stable (17.6.5.7 [algorithm.stable]).
Change 25.4.1.2 [stable.sort]/4 as indicated:
template<class RandomAccessIterator> void stable_sort(RandomAccessIterator first, RandomAccessIterator last); template<class RandomAccessIterator, class Compare> void stable_sort(RandomAccessIterator first, RandomAccessIterator last, Compare comp);[.]
-4- Remarks: Stable (17.6.5.7 [algorithm.stable]).
Change 25.4.4 [alg.merge] as indicated:
template<class InputIterator1, class InputIterator2, class OutputIterator> OutputIterator merge(InputIterator1 first1, InputIterator1 last1, InputIterator2 first2, InputIterator2 last2, OutputIterator result); template<class InputIterator1, class InputIterator2, class OutputIterator, class Compare> OutputIterator merge(InputIterator1 first1, InputIterator1 last1, InputIterator2 first2, InputIterator2 last2, OutputIterator result, Compare comp);[.]
-5- Remarks: Stable (17.6.5.7 [algorithm.stable]).
[.]
template<class BidirectionalIterator> void inplace_merge(BidirectionalIterator first, BidirectionalIterator middle, BidirectionalIterator last); template<class BidirectionalIterator, class Compare> void inplace_merge(BidirectionalIterator first, BidirectionalIterator middle, BidirectionalIterator last, Compare comp);[.]
-9- Remarks: Stable (17.6.5.7 [algorithm.stable]).
2128. Absence of global functions cbegin/cend

2148. Hashing enums should be supported directly by std::hash

2149. Concerns about 20.8/5
This wording is relative to N3485.
Edit 20.8 [function.objects] p5:

Otherwise, if uses_allocator<T1, inner_allocator_type>::value is true and is_constructible<T1, allocator_arg_t, inner_allocator_type, Args1...>::value is true, then xprime is tuple_cat(tuple<allocator_arg_t, inner_allocator_type&>( allocator_arg, inner_allocator

Change 21.4.2 [string.cons]/6 as indicated:
basic_string(const charT* s, size_type n, const Allocator& a = Allocator());-6- Requires: s

shall not be a null pointerpoints to an array of at least traits::length(s) + 1 elements of charT.
