These follow the conversion conventions of std::reverse_iterator, which are off-by-one: the newly-constructed "reverse" iterator dereferences to the previous node of the one sent in. This has the benefit of converting reverse ranges in place: - If [I, E) is a valid range, - then [reverse(E), reverse(I)) gives the same range in reverse order. ilist_iterator::getReverse() is unchanged: it returns a reverse iterator to the *same* node. ------------------------------------------------------------------------ ------------------------------------------------------------------------ r294357 | dblaikie | 2017-02-07 13:31:03 -0800 (Tue, 07 Feb 2017) | 1 line Fix some missing negations in the traits checking from r294349 ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_40@294477 91177308-0d34-0410-b5e6-96231b3b80d8
