[PATCH] D75929: [DebugInfo] Support DWARFv5 index sections.

[Igor Kudrin via Phabricator via llvm-commits]

ikudrin updated this revision to Diff 249939.
ikudrin added a comment.

- Use values for clashing identifiers proposed by @dblaikie.
- Convert all unknown section identifiers into a special value, `DW_SECT_EXT_unknown`; Use an optional parallel array to keep the raw values of unknown identifiers.
- Split the refactoring part in `llvm-dwp.cpp` into a separate patch, D76067 <https://reviews.llvm.org/D76067>.

There are some other changes that can be split into separate patches. I will make the series when the direction of this patch is approved in general.
