If you mean you just want to see how a particular binary was built, the
easiest way is "objdump --disassemble foo | grep ldrh" or some such.

That's correct. But you won't save much that way -- halfword operations don't
dominate the kernel by any means, and you only save a couple of words per
instance. What were the relative sizes of the two vmlinux files?
