This allows iterators to assert when they are dereferencedoutside of their bounds.As a fly-by change, this commit removes the _LIBCPP_ABI_SPAN_POINTER_ITERATORSknob. Indeed, not using a raw pointer as the iterator type is useful toavoid users depending on properties of raw pointers in their code.This is an alternative to D127401.Differential Revision: https://reviews.llvm.org/D127418 List of files: /llvm-project-15.0.7/libcxx/test/std/containers/views/views.span/span.sub/first.verify.cpp Mon, 06 Jun 2022 18:01:38 +0000 Louis Dionne <ldionne.2@gmail.com>
