The Return of the Frame Pointers

Brendan Gregg

The problem is that this system has a default libc that has been compiled without frame pointers, so any stack walking stops at the libc layer, producing a partial stack that's missing the application frames. But I'd rather the cost be zero, of course! We may get there with future technologies I'll cover later.
