Common symbols are not undefined, at least for ObjectFile. They are implemented like that in some object formats, but for the interface provided by lib/Object, SF_Undefined and SF_Common are different things. This matches the ELF and COFF implementation and fixes llvm-nm for MachO. llvm-svn: 241587 2015-07-07 22:26:39 +08:00			`// RUN: llvm-mc %s -o %t -filetype=obj -triple=x86_64-apple-darwin`
