With this patch only the name is set. I will set the other fields shortly. For now the table doesn't include local symbols. This is equivalent to using --discard-all with gnu ld. This is OK for now since the symbols are not needed for execution and for testing symbol resolution we only need the global symbols. llvm-svn: 245044
