Looks perfect to me. So we are not the first architecture needing
such tricks... AVR would need 3 new relocs, used like this:
.word pm16(label)
ldi r30,pm16_lo8(label)
ldi r31,pm16_hi8(label)
and the linker can do the rest of the magic (add jumps in a section
below 64K words if the label is above).
Cc: to Denis, as I may need help actually implementing these changes
(you know binutils internals much better than I do).
Thanks,
Marek
