[PATCH] D124287: [modules][ODRHash] Compare ODR hashes to detect mismatches in duplicate ObjCInterfaceDecl.

[Volodymyr Sapsai via Phabricator via cfe-commits]

vsapsai added a comment.

As a proof of concept how ODR hash comparison can be used during  deserialization, please see D124289 <https://reviews.llvm.org/D124289>. My point is to highlight the amount of reuse we gain from using ODR hash (I particularly enjoy the test case reuse). I agree the error messages aren't particularly useful yet and it will take some work to make code in `ASTReader::diagnoseOdrViolations` usable from parser. But I believe that should be doable.
