Summary: MetadataAsValue uses a canonical format that strips the MDNode if it contains only a single constant value. This triggers an assertion when trying to cast the value to a MDNode. Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D7165 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@227319 91177308-0d34-0410-b5e6-96231b3b80d8
