But I digress. This is just to say that gcc shouldn't pull __aeabi_uldivmod in this case because:
There isn't a library call (or instruction) for a straight 'mod' operation, so GCC always has to use 'divmod', no exceptions.
In any case, optimization of a div and a mod into a single call is problematic, at best, so it's unlikely that's happening. See GCC PR43721.
Ah, sorry. So the divmod call is there due to the modulo operation only.
