While using gcc, I've noticed that some static functions appear in the symbol table while others do not. What are the conditions that control when a static function's symbol appears? I would have thought all statics would not be included.
At a high level, a static function whose calls in a program are all inlined will not have an entry in the symbol table. A static function that's not completely inlined will. What is and isn't inlined depends on optimizations in effect and on attributes (e.g., function with the always_inline attribute will likely not a have a symbol even at -O0, while a trivial static function that's declared with attribute noinline will even at -O1 and higher).
