Hello, as the title, is there a way can return gimple stmt is a function or not,for example:int a( ){ printf("this is fn a");}int main( ){ a(); return 0;}In the main function line:1, it calls the function a. And when this code turns into gimple stmt, it will be "a();" as the same.So when I read the gimple stmt, how can I determine the stmt "a();" is a function? Thank you.
