They are as much trouble as aliases to declarations. They are requiring the code generator to define a symbol with the same value as another symbol, but the second symbol is undefined. If representing this is important for some optimization, we could add support for available_externally aliases. They would be *required* to point to a declaration (or available_externally definition). llvm-svn: 254170
