+From ae27211cbbfb63a0ad3c141cd1310d7f583ec40e Mon Sep 17 00:00:00 2001

+Subject: [PATCH] tests: Handle zero directory entry in .debug_line DWARF5
+ debugedit.at
+
+We were skipping the zero directory entry, because it was always
+the same as the directory entry at position one. But that isn't
+true anymore with gcc 11.2.1. There the zero dir entry is unique.
+Fix the debugedit.at .debug_line testcases using DWARF5 to also
+include dir entry zero.
+
