From fe6bd21a0bda55abf859223648f31710772eb1eb Mon Sep 17 00:00:00 2001 From: =?utf8?q?Fran=C3=A7ois=20Dumont?= Date: Thu, 8 Mar 2018 06:26:15 +0000 Subject: [PATCH] printers.py (NodeIteratorPrinter): New. MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 2018-03-08 François Dumont * python/libstdcxx/v6/printers.py (NodeIteratorPrinter): New. (StdListIteratorPrinter): Inherit from latter. (StdFwdListIteratorPrinter): New, inherit from latter. (StdDebugIteratorPrinter.to_string): Use non-debug iterator printer when iterator has no associated container. (build_libstdcxx_dictionary): Add __gnu_cxx::_Fwd_list_iterator and __gnu_cxx::_Fwd_list_const_iterator printers. Remove __norm namespace registrations. * testsuite/libstdc++-prettyprinters/debug.cc: Adapt. * testsuite/libstdc++-prettyprinters/debug_cxx11.cc: Adapt.
