Hi all,

I have something to ask for the ppc kernel source.

#define LOADADDR(rn,name)           \
   lis     rn,nam...@highest;      \
   ori     rn,rn,nam...@higher;    \
   rldicr  rn,rn,32,31;            \
   oris    rn,rn,nam...@h;         \
   ori     rn,rn,nam...@l

Is ## used for concatenation. I'm not sure because it is just meaningless.
If so what on earth is the result of concatenating ?

And is there a good reference to understand powerpc asm ?
I'm reading Power ISA, but I can't find @highest, @higher and ##.
It would be good to know the reference book.

Thanks in advance.


Regards,
HongWoo.
