part of the error message. As the caller is the one that needs to add the name of where the "object file" comes from to the error message as the object file could be in an archive, or coming from a slice of a Mach-O universal file or a buffer created by a JIT. In the cases of a Mach-O universal file the architecture name may or may not also need to be printed which is up to the tool code. For example if the tool code is only selecting the host architecture slice then that architecture name is never printed. This patch is the change to the libObject code and there will be follow on commits for changes to the code for each tool. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@268789 91177308-0d34-0410-b5e6-96231b3b80d8
