Unfortunately it's not that simple. The push instruction may cause an

If we just concatenate the C code of the two procedures, won't gcc take care of that for us? Or could scheduling mess this up? Maybe there's a switch to avoid having it reschedule instructions in a way that side effects happen in a different order? (that would still give us the advantage of CSE and peephole optimizations)
