Subject: [PATCH] tests: Handle zero directory entry in .debug_line DWARF5
|
|
|
55887d |
debugedit.at

|
|
|

We were skipping the zero directory entry, because it was always
|
|
|
55887d |
the same as the directory entry at position one. But that isn't
|
|
|
55887d |
true anymore with gcc 11.2.1. There the zero dir entry is unique.
|
|
|
55887d |
Fix the debugedit.at .debug_line testcases using DWARF5 to also
|
|
|
55887d |
include dir entry zero.
