* Add getSymbolAlignment to the ObjectFile interface.Rafael Espindola2013-04-291-0/+6
| | | | | | | | | | | | | For regular object files this is only meaningful for common symbols. An object file format with direct support for atoms should be able to provide alignment information for all symbols. This replaces getCommonSymbolAlignment and fixes test-common-symbols-alignment.ll on darwin. This also includes a fix to MachOObjectFile::getSymbolFlags. It was marking undefined symbols as common (already tested by existing mcjit tests now that it is used). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180736 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | politely report it instead of running into llvm_unreachable. Also patch llvm-dwarfdump to actually check whether the file it's attempting to dump is a valid object file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173489 91177308-0d34-0410-b5e6-96231b3b80d8
