--- Comment #8 from Ian Lance Taylor <ian at airs dot com> --- The naming is confusing and but the idea seems sound. It doesn't make sense for a static symbol to be DECL_ONE_ONLY. But currently DECL_ONE_ONLY just means that the symbol has a comdat group. So given that, I guess it makes sense to speak about DECL_ONE_ONLY && !TREE_PUBLIC meaning a static symbol in a comdat group, where the signature for the comdat group must obviously be some other symbol.
