Sounds like what a lot of other tools out there do during development
work. Sounds like you want something for production however. Not
something I'd advocate. However...
Have a global variable, and (re-)hash it every time at the start of a
function call (or wherever in your code you want a path to be noted)
with either a fixed number or the current line number in that file.
The eventual hash should give you some sort of indication of the path
taken.
static hash_val;
void rehash(long l_val){
// your hash function here to change hash_val with l_val)
}
int foo(...){
rehash(__LINE__);
// body of foo();
}
float bar(...){
rehash(__LINE__);
// body of bar();
}
... etc.
Generating the lookup table will not be fun however.
