tberghammer updated the summary for this revision.
tberghammer updated this revision to Diff 33676.
tberghammer added a comment.
[RFC] DO NOT COMMIT!
Update the design based on the discussion for the previous diff.
The current version have ~35 failures with split dwarf (most of them hit an
assertion in clang) and causes a minor regression in non-split dwarf handling.
I am working on these issues, but would like to get a feedback about the
current design because a major change there can shuffle up everything.
