No, I just know that some targets like to align functions to
cache-lines. This is a useful speed optimization, but does lead to lots
of "blank" gaps in the code. I have no real idea if ARM does this kind
of thing, or if the ABI has anything to say about it.
I just suggest that we should check it out - or at least ask an ARM
expert if I'm talking nonsense. :)
