[PATCH] D130516: [Support] compression classes

[David Blaikie via Phabricator via cfe-commits]

dblaikie added inline comments.


================
Comment at: clang/lib/Serialization/ASTWriter.cpp:2003-2004
   // consumers will not want its contents.
+  llvm::compression::CompressionAlgorithm CompressionScheme =
+      llvm::compression::ZlibCompressionAlgorithm();
+
----------------
Doesn't this cause slicing & end up with the base implementation?

(also the base class `CompressionAlgorithm` has no virtual functions, so I'm not sure how this is meant to work - does this code all work? Then I must be missing some things - how does this work?)
