In GCC4.4 function test presents 2 callees foo() and bar() and the

because callees in cgraph is 0x0. I wonder if this information is not
available anymore at this point and if there's something I can do about it.
After some digging around I noticed GCC4.5 introduces:
NEXT_PASS (pass_remove_cgraph_callee_edges);
I am wondering why this is being done. Are we just freeing resources or
is there any other reason? Is there any other way to find callees
without this information?
