[PATCH] D124082: [Debuginfo][llvm-dwarfdump][dsymutil] Add dsymutil compatibility dump.

[Jonas Devlieghere via Phabricator via llvm-commits]

JDevlieghere added a comment.

When you used this to compare the output of dsymutil changes, what was the input binary? Does this generate meaningful output for bigger programs like dsymutil itself?

In my experience, when you change the dsymutil algorithm that marks dies as kept, they end up in different subtrees. Is that something this tool can deal with? My original assumption was that it can't, but then I don't understand how this was useful for the other two patches.

+1 if that tool is actually coming. @CarlosAlbertoEnciso or @probinson do you have a rough timeline in mind?
