The C++ committee has confirmed that passing a null pointer to the unary basic_string_view constructor is undefined. This removes the check from our implementation, and adds the nonnull attribute to warn when the compiler can detect undefined input. * include/std/string_view (basic_string_view(const CharT*)): Remove check for null pointer and add nonnull attribute. (compare(const CharT*), compare(size_type, size_type, const CharT*)) (find(const CharT*, size_type), rfind(const CharT*, size_type)) (find_first_of(const CharT*, size_type)) (find_last_of(const CharT*, size_type)) (find_first_not_of(const CharT*, size_type)) (find_last_not_of(const CharT*, size_type)): Add nonnull attribute. * testsuite/21_strings/basic_string_view/cons/char/nonnull.cc: New. * testsuite/21_strings/basic_string_view/operations/compare/char/ nonnull.cc: New. * testsuite/21_strings/basic_string_view/operations/find/char/ nonnull.cc: New. * testsuite/21_strings/basic_string_view/operations/rfind/char/ nonnull.cc: New.
