Hi, I noticed that since recently UpgradeDebugInfo (Which is called for loading any bitcode from disk/memory) does a full bitcode verification. Is this on purpose or is this a mistake? Seems to have a fair amount of overhead.

Hi all, Sometimes llvm::UpgradeDebugInfo <http://llvm.org/docs/doxygen/html/namespacellvm.html#ad3c29183c5faa7f5a352807af8aca268> drops debug info which is pretty compatible with recent llvm version ( http://stackoverflow.com/questions/27023713/missing-debug-metadata-in-llvm-after-xcode-update ) and sometimes it drops something real...
