I agree completely: -mcall-prologues is still desired if it produces smaller

OK, you may be right it still makes sense on the very small devices
(I don't have a strong opinion, just a suggestion), though it's still
possible to use the old toolchain with the old devices. I certainly
don't see much point in supporting it on the large (3-byte PC) devices.
In fact, this brings up the question as to why it is not the default?
It's a tradeoff: smaller, but slower.

Can the default be made dependant on the core? Certainly 3-byte PC
cores will have enough program space, but the for the smaller cores, you
normally want to save space.
Alternatively, can the setting follow the optimisation flags? -Os gives
call prologues, -O2 gives inline prologues?
