Summary: That way llvm-objdump can rely on it without adding an extra dependency on CodeGen. This change duplicates the FaultKind enum and the code that serializes it to a string. I could not figure out a way to get around this without adding a new dependency to Object Reviewers: rafael, ab Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D10619 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@240364 91177308-0d34-0410-b5e6-96231b3b80d8
