As emutos supports 68060, maybe they could add such fpu soft emulation
in emutos too ?
The Motorola Floating Point Support Package (FPSP) is quite large in
size, over 50 kB compiled, even without the required OS hooks:
https://github.com/torvalds/linux/blob/master/arch/m68k/ifpsp060/fpsp.sa
Since EmuTOS is always limited by ROM space (even in the 512k versions),
personally, I don't see that we would include FPU emulation for the
68060 into EmuTOS. I'd rather suggest making an AUTO folder program out
of the FPSP, if that doesn't already exist.

PS: The one instruction that EmuTOS does emulate on the 68060 is MOVEP.
I presume that is because afaik it's used in PureC startup code and,
therefore, in many applications.
