[PATCH] D71582: llvm-diff: Perform structural comparison on GlobalVariables, if possible

[Dominic Chen via Phabricator via llvm-commits]

ddcc added a comment.

Which linkage types specifically? `hasUniqueInitializer()` checks `!isExternallyInitialized()` and `isStrongDefinitionForLinker(`), which expands to `!isDeclarationForLinker()` (`!hasAvailableExternallyLinkage() && !isDeclaration()`) and `!isWeakForLinker()`), which I believe limits the variable to private and internal linkages.
