Hi,
In idle_6xx.S one finds instructions like:
lis r4,[EMAIL PROTECTED]
lwz r4,[EMAIL PROTECTED](r4)
Can someone explain what this is doing? Presumably the first is loading
an address and the second a value. What do the '@ha' and '@l' do?
Also, is there any performance difference between:
lbz rD,d(rA)
lhz rD,d(rA)
lwz rD,d(rA)
While I'm wasting your time, I picked up an ADB infrared wireless
keyboard. I think it works. But not under Linux. Should it?
And is there any reason to prefer one over the other for doing byte
swapping:
lwbrx rD,rA,rB
stwbrx rS,rA,rB
