--- Comment #4 from Jeffrey A. Law <law at redhat dot com> --- Certainly possible. We ought to be able to see the problem at the assembly level with a cross compiler, which will help greatly with debugging :-) I wonder if the ICF framework unified the gate function with something else. That ought to show up in the .icf dump.
