--- Comment #7 from qinzhao at gcc dot gnu.org --- (In reply to Jakub Jelinek from comment #6) > That is a bad example, __builtin_call_with_static_chain is not a builtin > function, but a keyword. A little confused here, this function is clearly listed as a built_in function provided by gcc, why it's not a builtin function? can you explain a little bit here? is it convenient for you to provide a good example for reference? thanks.
