Hello Shubham, Thank you for the reply! I see. That's strange, the `f` pointer turns out to be invalid. May I ask when would the corresponding struct be initialized?
And I am attaching the corresponding GIMPLE IR code. As you can see, I am traversing to the following statement: r_9 = foo (a_6, d_2); And trigger the above procedure. Function `foo` has been traversed before this statement which means the corresponding function* should have been created already?
