I think you need to explain why this change is desirable/necessary for LTO, this would be a good starting point. As for setting TREE_ADDRESSABLE on every single global symbol in every single front-end, why not, but this seems more complicated than treating global symbols as so by default (in non-LTO mode). -- Eric Botcazou
