Well the 476 implements ISA 2.05, which I think has added a fair amount over the 440. Not to mention the 476 core that has been released has a FP unit. I'll note that GCC has support for a 476 with and without a FP unit, even though AFAIK, we only ship one with a FP unit. The relevant options are -mcpu=476 (no FP unit) and -mcpu=476fp (with FP unit). Basically, -mcpu=476 is equivalent to -mcpu=476fp -msoft-float. > @@ -53,7 +58,12 @@ > mullw r10,r0,r4 # and get the remainder > add r8,r8,r0 > subf r6,r10,r6 > +#ifdef CONFIG_INVADER > 4: stw r7,0(r3) # return the quotient in *r3 > stw r8,4(r3) > +#else > +4: stw r7,0(r3) # return the quotient in *r3 > + stw r8,4(r3) > +#endif > mr r3,r6 # return the remainder in r3 > blr This looks like a typo, since you didn't actually swap the offsets on the stw's like you did in all of the other patch hunks.
