The size of common symbols is now tracked correctly, so they can be listed in the arange section without needing knowledge of other following symbols. .comm (and .lcomm) do not indicate to the system assembler any particular section to use, so we have to treat them as having no section. Test case update to account for this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191210 91177308-0d34-0410-b5e6-96231b3b80d8
