cc/gcc/egcs kernel compilation options?

[Barrie Spence]

As a PPC newbie, why do we need/use "-msoft-float"? Is this 
to handle some processor implementations that don't have 
floating-point hardware? (and if so, does it have any overhead 
on the 603/604/G3 Macs?). If it does have some cost, could it 
not be enabled in the same way as on Intel?

Next question, is there any advantage to building a kernel
with "-mcpu=604 -mtune=604"? (or whatever is most appropriate).

Thanks,
	Barrie
