From 7323259de884f4576d78e6492b93fc2455617ef5 Mon Sep 17 00:00:00 2001 From: Jonas Devlieghere Date: Tue, 30 Oct 2018 18:25:28 +0000 Subject: [DebugInfo] Define base function on DWARFDie reverse iterators This defines member function base on the specialization of std::reverse_iterator for DWARFDie::iterator as required by C++ [reverse.iter.conv]. This fixes unit test DWARFDebugInfoTest.cpp under EXPENSIVE_CHECKS which currently can't be built due to GNU C++ Library calling this member function in debug mode.
