I think you're looking at !AEABI case.

The AEABI case is worse. It ends up getting the code from
include/asm-generic/div64.h after defining a few helper inline asm
functions.

It's probably best if you start taking some recreational drugs
_before_ looking at that code.  It might make you go "Ooh, kewl!"
instead of trying to dig out your eyeballs with a rusty spoon.
