Good enough?


For PPC, a inner loop of mgrid (I don't know if this is a major inner loop or
not because I was just looking at the asm), we improve a lot.
We go from:
lfd f0,0(r2)
lfd f13,8(r2)
addi r2,r2,8
To:
fmr f0,f12
lfdu f12,8(r9)


So we changed one load to a move so SMS actually worked in this case with
your patch which is cool.
