--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Guess DECL_UNINLINABLE, maybe DECL_PRESERVE_P, TREE_USED, maybe DECL_USER_ALIGN/DECL_ALIGN, maybe DECL_WEAK, maybe DECL_NO_INSTRUMENT_FUNCTION_ENTRY_EXIT, DECL_NO_LIMIT_STACK. TREE_READONLY, DECL_PURE_P, TREE_THIS_VOLATILE (for const, pure and noreturn attributes) probably makes no sense, DECL_IS_RETURNS_TWICE neither (returns_twice ctor?). What about TREE_NOTHROW? DECL_FUNCTION_SPECIFIC_OPTIMIZATION, DECL_FUNCTION_SPECIFIC_TARGET...
