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

See -finstrument-functions in the GCC documentation. You may want to use dladdr() in the debugging function, which may also require linking with -Wl,-export-dynamic.
