I see.  As far as I know, these linkage types make a symbol visible to external code, so their DSNodes should be marked External.

But running internalize as preprocessing helps.

I guess that is the correct solution.

Yes, you have to run the internalize pass when doing whole program analysis in order to get any good optimization or analysis results out of any properly written LLVM pass.  Even LLVM's libLTO results would be pessimized if it didn't run internalize first.

DSA checks whether or not a function has InternalLinkage to mark it external. Do we not care about all the other linkage types? Arent there others that could be considered non-external?

Which other linkage types do you think should be internal?
