llvm-dsymutil was misinterpreting the value of common symbols as their address when it actually contains their size. This didn't impact llvm-dsymutil's ability to link the debug information for common symbols because these are always found by name and not by address. Things could however go wrong when the size of a common object matched the object file address of another symbol. Depending on the link order of the symbols the common object might incorrectly evict this other object from the address to symbol mapping, and then link the evicted symbol with a wrong binary address. Use the new ability to have symbols without an object file address to fix this. llvm-svn: 259318
