I notice that this discussion seems focused around ARM-mode
instructions. Is that intentional? In my experience everyone that
actually cares about code size is using Thumb mode (mostly because
they're on M-class CPUs).

It might be intentional, but I just wanted to make sure before a lot
of effort was spent on marginal cases.
