Eric Fiselier 706e2c7374 Diagnose when reverse_iterator is used on path::iterator. path::iterator isn't a strictly conforming iterator. Specifically it stashes the current element inside the iterator. This leads to UB when used with reverse_iterator since it requires the element to outlive the lifetime of the iterator. This patch adds a static_assert inside reverse_iterator to disallow "stashing iterator types", and it tags path::iterator as such a type. Additionally this patch removes all uses of reverse_iterator<path::iterator> within the tests. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@300164 91177308-0d34-0410-b5e6-96231b3b80d8	9 years ago

Eric Fiselier 706e2c7374 Diagnose when reverse_iterator is used on path::iterator.

path::iterator isn't a strictly conforming iterator. Specifically
it stashes the current element inside the iterator. This leads to
UB when used with reverse_iterator since it requires the element
to outlive the lifetime of the iterator.

This patch adds a static_assert inside reverse_iterator to disallow
"stashing iterator types", and it tags path::iterator as such a type.

Additionally this patch removes all uses of reverse_iterator<path::iterator>
within the tests.
