In case of hash collision, can't we just compare function body, byte by byte? Shouldn't be a big performance hit I think.
This is the part where Ian said "without help from the linker". The linker has no reason to do this unless we tell it, and the compiler doesn't see the other function body at the time of generating the hash (since it could be in another .o file).
