I see it handy to debug cgraph_edge and I've dumped it manually many times.
Maybe it's time to come up with the function? Example output:
(gdb) p e->debug()
ag/9 -> h/3 (1 (adjusted),0.25 per call)
ag/9 (ag) @0x7ffff773eca8
Type: function definition analyzed
Visibility: public
next sharing asm name: 7
References: table/5 (addr)
Referring:
Function ag/9 is inline copy in ap/4
Clone of ag/7

Ready to be installed?
Thanks,
