[PATCH] D22030: [PGO] Change the ProfileSummary metadata merge behavior

[Easwaran Raman via llvm-commits]

eraman added a comment.

All the modules are expected to have the same profile summary and changing the behavior to a warning is not the right thing to do. If we want to support a use case where we LTO files with different profile data, perhaps we should have a way to disable profile summary for those builds? That seems better than picking the first summary we see (as would be the case with a warning)
