Re: cgraph callees availability

In GCC4.4 function test presents 2 callees foo() and bar() and the
sibcall is not done. In GCC4.5 the sibcall is done (but shouldn't)
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?
