2011-07-19 François Dumont <francois.cppdevs@free.fr> * include/debug/safe_unordered_base.h, safe_unordered_sequence.h, safe_unordered_sequence.tcc, safe_local_iterator.h, safe_local_iterator.tcc: New, support for unordered sequence safe local iterators. * include/Makefile.am: Add previous files. * include/Makefile.in: Regenerate. * include/debug/unordered_map, unordered_set: Implement _Safe_unordered_sequence and expose _Safe_local_iterator. * include/debug/safe_iterator.h, safe_iterator.tcc: Refactor _Safe_iterator::_M_get_distance static method to expose it as __get_distance function and use it in _Safe_local_iterator type. * include/debug/formatter.h: Add __msg_local_iter_compare_bad _Debug_msg_id enum entry to notify invalid comparison between local iterators from different buckets. Add _Parameter constructor from _Safe_local_iterator. * include/debug/functions.h: Add __valid_range overload for _Safe_local_iterator. * src/debug.cc: Add _Safe_unordered_sequence_base and _Safe_local_iterator_base methods implementations. * config/abi/pre/gnu.ver: Add export of some _Safe_unordered_sequence_base and _Safe_local_iterator_base methods. * testsuite/util/debug/checks.h: Add use_invalid_iterator function to simulate use of a singular iterator. * testsuite/util/debug/unordered_checks.h: New, several functions to simulate classic invalid usage of unordered sequence local iterators. * testsuite/23_containers/unordered_map/debug/ use_erased_local_iterator_neg.cc, invalid_local_iterator_range_neg.cc, use_invalid_local_iterator_neg.cc, use_invalid_iterator_neg.cc, invalid_local_iterator_compare_neg.cc: New. * testsuite/23_containers/unordered_multimap/debug/ use_erased_local_iterator_neg.cc, invalid_local_iterator_range_neg.cc, use_invalid_local_iterator_neg.cc, use_invalid_iterator_neg.cc, invalid_local_iterator_compare_neg.cc: New. * testsuite/23_containers/unordered_set/debug/ use_erased_local_iterator_neg.cc, invalid_local_iterator_range_neg.cc, use_invalid_local_iterator_neg.cc, use_invalid_iterator_neg.cc, invalid_local_iterator_compare_neg.cc: New. * testsuite/23_containers/unordered_multiset/debug/ use_erased_local_iterator_neg.cc, invalid_local_iterator_range_neg.cc, use_invalid_local_iterator_neg.cc, use_invalid_iterator_neg.cc, invalid_local_iterator_compare_neg.cc: New.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*.
