Anyone can suply code or suggest where to look/what to do,
in order to modify gcc to produce a call to a user function
before every source line (or every basic block)?

In essence, I think this could be done by hacking -a to produce
a function call instead of direct counting code. 


Note: I have not, todate, hacked gcc - only gdb.

Thanks!
