Hi all,
I was reading kernel level source and found this macro.
#define SET_REG_TO_LABEL(reg, label) \
lis reg,(label)@highest; \
ori reg,reg,(label)@higher; \
rldicr reg,reg,32,31; \
oris reg,reg,(label)@h; \
ori reg,reg,(label)@l;
But, I couldn't find any clue related with @highest, @higher, @h, @l.
If anybody know about this directives(?), please explain it.
Or just let me know the keyword, so I can search with those keyword.
Thanks in advance.
HongWoo.
