How to tell gcc to instrument the code with calls to my own function each _line_ of code?

Question

For example, there is the source:

void my_special_debugging_function(const char* function_name, const char* file_name, int line_number);

void func1() {
             


        

Answer 1

As stated in the other answer, I don't think that there is any way to tell GCC to do that, without preprocessor tricks and edits to the source code. – nategoose
